I did not expect much given the price but I did not expect this one to be this bad. In fact, this is so bad that the sequential read and write speeds are only twice the speed of my old Toshiba 1TB Hard Drive benchmarked for comparison. The only saving grace for this are the 4k read and write speeds. They're 8-10x the speed of my HDD, which explains why it boots up faster than my HDD but this is still bad for this type of Solid State Drive. Other brands like Samsung and Corsair have 80-90MB/s read and write speeds at 4k tests and blows competition at the Sequential Read and Write Speeds. If you don't believe me, just look at benchmarks online for those products or look at my laptop SSD for reference/comparison. I should've saved more for other better SSDs like ... MoreI did not expect much given the price but I did not expect this one to be this bad.

I know this one is cheap but you could at least advertise the right read and write speeds so us consumers will know what we're getting into.EDIT: Lazada is removing pics of benchmark

A little less than perfect.

I bought this drive, as an exact match to my existing drive, so I could clone my current drive and be ready to go with my new one for several years. However, the new one came with a "bad sector", so my software would not clone the drive.I returned the drive and purchased another. They were in transit at the same time, so I know I received a different drive, but the second drive also had a "bad sector". I was not able to use this one either.I have always thought of SanDisk as a top-notch company, until now. It appears either they have a design issue or poor quality control now.I no longer recommend SanDisk and will look for another brand that I can trust.Also, SanDisk stopped supporting their own cloning software, or I could no longer find it. Another disappointment.

SSD from Sandisk was my first SSD. I bought this on sale in 2018 and still use it today. The build quality is similar to all other SSDs, plastic and light. Which is not meant negatively. I was initially skeptical about SanDisk's SSDs because the USB sticks didn't last long. The SSD has now been running for 6 years without any problems. Whether during commissioning, reinstalling Windows or the speeds. It runs 1A. Higher rates are guaranteed to be achieved with some competing models, but the measured values ​​are satisfactory.My expectations at that time were completely fulfilled and even more. The SSD had to go through several moves. She also had to suffer from high temperatures due to her apartment.

The SanDisk Extreme Portable SSD V2 is SanDisks newest model of small, portable, highcapacity Solid State Drives SSD, with a notable improvement in data transfer speed capabilities over its predecessor the SanDisk Extreme Portable SSD V1. SanDisk and its parent company since 2016, Western Digital have long been a highly respected and popular manufacturer of computer storage including hard disk drives, flash memory products and SSD devices.

SanDisk and its parent company since 2016, Western Digital have long been a highly respected and popular manufacturer of computer storage including hard disk drives, flash memory products and SSD devices. I rely on Western Digital and SanDisk for many of my own storage products because they have always proven to be very reliable products with excellent performance. SanDisk has cultivated an outstanding reputation for their flash memory cards and drives and for their solid state drives. The new Extreme Portable SSD V2 excels in several important waysThe Extreme Portable V2 is available in 500 GB, 1 TB and 2 TB models. The black enclosure appears to be constructed of nonmetallic composite which is clad on five sides by a silicone rubber material which from appearances should prove to be both rugged and durable. This is a mostly sealed device which is IP 55 rated for dust and water resistance. The IP 55 rating does not certify that a device is waterproof or submersible. An IP 55 rating indicates that a device is protected from limited dust ingress and from low pressure water jets. The USBC port does not have a sealing cover however. The dimensions of the Extreme Portable V2 are 4 78 in length x 2 in width x 716 in thickness. It is both light weight, and compact.Portable SSDs are extraordinarily convenient and useful for many purposes. Video content producers find them to be essential. Given their large capacity and high data transfer rates they are ideal for those purposes as well as data backup and storage, and notably, for use as a portable file store when using multiple computers, and particularly when travelling away from home or primary workplace.The SanDisk Extreme Portable SSD V2 is generally well suited to working when away from a primary computer. When travelling light, the SanDisk Extreme SSD is a good accompaniment to an extremely portable 13.3 Chromebook, as long as the SanDisk Extreme is not utilizing password protection data encryption security with the included, SanDisk Security Software. That compact, lightweight pair obviously cant run AutoCAD, but they easily accommodate working with Microsoft Office files, Adobe Acrobat files and other functionality not requiring hauling around a large, heavy and powerful laptop. However, if SanDisk Security Software is utilized, only Windows and Mac OS computers are supported.Most users will probably choose to utilize password protection and data encryption, and therein lie additional minor nuisance issues that I encountered, beyond the inability to utilize the SanDisk Security protected SSD with a Chromebook.The SanDIsk Security Software installation exe file for Windows computers and a zip file for Macs is located on the drive. The SanDisk Security Software installs on a host computer via that executable file on the SSD. The installed software is required in order to create, change or remove password protection and AES 256 Bit encryption on the SanDisk Extreme Portable V2 SSD. Unlocking the SSD can be accomplished with the SanDisk Security software application. However, the SanDisk Security software is not required to unlock the SSD. The SSD can also be unlocked on any Windows or Mac computer, without the SanDisk Security Software, via the SanDisk Drive Unlock Utility, which creates a Virtual CD Drive on the attached computer. Unfortunately, neither the SanDisk Security Software application, nor the SanDisk Unlock Utility work with Chrome OS.The SanDisk Security Software offers the option to AutoUnlock, on an attached computer with the full SanDisk Security Software installed. A convenient option, but antithetical to maximum access restriction security for the data on the SSD.When using the SanDisk Security Software I found that the time for the mounted SSD to be recognized by the Security Software averaged approximately 33 41 seconds. After entering the password, there was an average wait of approximately 8 10 seconds for the SSD to unlock. This period of roughly 50 seconds seems like a long delay when you are attempting to access your files. I am compelled to remark that when utilizing a competitors 1 TB SSD, which similarly provides AES 256 Bit encryption and password protection, and also includes a biometric security feature, that drive is recognized immediately, and unlocks instantly.Furnished in the box with the SanDisk Extreme Portable SSD V2 is one, 6 USB 3.2 Gen 2 cable, terminated at both ends with USB Type C connectors. Also included, is a USB Type C to USB Type A adaptor. A 6 USB cable is absurdly short and is an impediment. Additionally, the small adaptor may easily be misplaced. Another SSD that I own included two, 17.5 long USB cables both a USB TypeA to USB TypeC cable and a USB TypeC to USB TypeC cable. The SanDisk Extreme Portable SSD should have two cables of decent, practical length, as well. There is a printed SSD Safety and Warranty Guide included, which includes a URL httpwww.downloads.sandisk.comdownloadsumssdinstallguide.pdf for downloading the PDF User Manual from the SanDisk website. Unfortunately, the URL printed in the guide is nonfunctional, and I could not locate a User Manual for this model anywhere on the SanDisk Support site. Perhaps the User Manual should have been included on the SSD.While exploring the SanDisk Support site, I downloaded and installed the SanDisk Dashboard, Version 3.1.2.5.. I was disappointed to discover that the SanDisk Dashboard software did not interact properly with this SSD. It did not display Drive Health, Temperature or S.M.A.R.T. passthrough data, etc. Nor did the diagnostics work with this SSD. Perhaps you will have better results with the Dashboard application I ultimately uninstalled it.The SanDisk Extreme SSD is preformatted in exFAT, with 512 byte sector size. There is no visual indicator for drive activity or power on the SanDisk Extreme SSD. I believe that an LED power drive activity annunciator would be beneficial.The high transfer rate specifications for the SanDisk Extreme SSD V2 are a very impressive 1050 Mbps for Sequential Reads and 1000 Mbps for Sequential Writes. Those fast data transfer rates are attributable to the PCIe Peripheral Component Interconnect Express bus, NVMe NonVolatile Memory Express memory and USB 3.2 Gen2 connectivity. However, those data transfer rates are only achievable when the host computer is similarly equipped with USB 3.2 Gen2 ports. The SanDisk Extreme PRO model SSD is rated at 2000 Mbps transfer speeds. My test speeds were limited by the USB 3.0 ports on both of the laptops available for testing. USB 3.0, data transfer rates were measured with Crystal DiskMark 7.0 at 458 Mbs Sequential Reads and 449 MBs Sequential Writes. Nevertheless, based on anecdotal observation, the SanDisk Extreme Portable SSD V2 was extremely fast. Very large file transfers were very fast. Data transfer rates did not appear to be affected at all by AES 256 Bit software encryption.The SanDisk Extreme Portable SSD V2 does become palpably warm when attached to a computer, even when idle, and generates heat in proportion to activity when it is actively in use. Large data transfers generate a lot of heat. I would presume that SanDisk employs a single layer PCM Phase Change Material to somewhat mitigate the heat generated by use presumably encapsulated paraffin wax. Nevertheless, the SanDisk Extreme SSD runs hot, and perhaps it may retain heat, rather than dissipate it effectively, as a consequence of the silicone rubber cladding which is likely insulative.Overall, the SanDisk Extreme Portable SSD V2 is a very good portable SSD. It offers large capacity and very fast data transfer rates. The IP 55 rating is a valuable asset for portable SSD drives particularly when travelling. SanDisk provides a five year warranty on the SanDisk Extreme Portable SSD V2, which certainly bests the typical three year warranties. The SanDisk Extreme Portable SSD V2 is certainly worthy of consideration and I am comfortable recommending it

In practical file transfer tests between this and another NVMe SSD drive connected to the same computer via M.2 where the other drive benchmarks faster in all regards, I was getting about 700 MBs read speeds and 465 MBs write speeds consistently fromto the SanDisk drive. For stability testing, I recorded many hours of highresolution, highbandwidth gameplay videos directly to the drive which went very smoothly with no hiccups. Design The rubberized body feels very sturdy, and I suspect could endure some significant punishment while protecting the internals from harm. The IP55 rated dust and water resistance, while not amazing, provides enough protection against mishaps to confidently take the unit on the go. Theres no plugcap for the USB port on the drive, which detracts somewhat from its otherwise rugged design. The carabiner loop is a nice touch for some added utility. One of the most unfortunateand arguably bizarredesign choices is the incredibly short USBC cable included. While barely sufficient for plugging this drive into a laptop or other small device tablet, phone, camera, etc., plugging this drive into a PC with a tower case is almost certainly going to require a much longer cable to avoid unintentional disconnects. Theres no power or activity light, and while not necessarily unusual, it is a feature that some may miss.

I bought one of these drives 8 months ago, feeling very confident from the reviews and especially that it was made by SanDisk, a very established company in this business. This was my very first SSD drive and it was on sale so I went ahead and bought one so I can use it mainly for my RAW photography photos and Lightroom catalogs. I felt if I was going to trust any drive to keep all this stuff in one place, it would be an SSD drive like this one.For the past 7 months Ive stored thousands of RAW photos on it which has been for my business and it has been a great drive, other than my small complaint of the cable disconnecting the drive from my computer which would happen sometimes just by simply moving or bumping the drive.

I felt if I was going to trust any drive to keep all this stuff in one place, it would be an SSD drive like this one.For the past 7 months Ive stored thousands of RAW photos on it which has been for my business and it has been a great drive, other than my small complaint of the cable disconnecting the drive from my computer which would happen sometimes just by simply moving or bumping the drive. But that was ok because its been a fast little drive and convenient to take on the go to do work on my laptop when needed so I was content enough with that.I use this drive pretty consistently since part of my work is shooting models, so I use it almost everyday to edit my photos through Lightroom.Today I was on my desktop computer iMac 27inch 2015 editing some photos in Lightroom when Lightroom froze up on me. I had to manually shut down my computer because the frozen Lightroom also prevented other things from working properly. Yes, frustrating....... but who hasnt had to do that before So whatever.Well when I booted my computer back up, the drive didnt mount. I figured it wasnt much of a problem. Id just reboot my computer again and Im sure itll mount. It didnt mount again. I rebooted one more time with no results. So I tried the drive on my laptop to see if it would mount there. Nothing. I tried another cable to make sure its not the cable. I still got nothing.Fortunately I back up all my RAW photos on another drive in case something like this happens, although I hadnt backed up my last shoot which is killing me right now.Needless to say I am incredibly frustrated and am now scanning the drive with a file recovery program hoping ill be able to recover at least these last photos that werent backed up. The data recovery program can see that the drive is connected to my computer even though the drive doesnt show as mounted.Coincidentally enough, a few days ago I just purchased another one of these exact drives my second one due to Black Friday deals. Now I dont know what to think or what to trust anymore I guess even an SSD drive isnt perfect. This one certainly isnt, and I was stupid enough to think this could be since I hear so many good things about SSD drives.I havent contacted SanDisk yet and I dont expect BH to take care of this since I bought it awhile back. Right now Im just hoping, hoping, HOPING to recover this last photoshoot I did which wasnt backed up yet. Ill just be happy for that at this point.As good as this drive may be in different areas, purchase with caution

I am a bit of a data backup junkie. I have been using a variety of desktop and portable hard drives for years and am never without a flash drive in my pocket.

With a smaller footprint and more rugged than traditional portable hard drives, this drive is super easy to pop in the pocket when going out the door.

I often use a tablet as a displaycontroller when shooting with a tripod mounted camera and with this drive I can create a local backup or completely offload the images and videos as I go without the need for an internet connection, a nice feature when photographing outdoors. This drive has made it very simple and faster than cloud based solutions when moving data between my PC, android tablet, and Chromebook laptop. Where it really shines for me is the ability to use it with my android tablet, which I could not do with my old portable HDD.I tested the drives speed against a portable HDD I have been using for a year or two with my laptop. I transferred a 21 gb photo and video file from my PC to each and the Sandisk SSD was about a minute faster. Not huge. However, on the other side, reading files especially the videos was noticeably faster on the Sandisk, with HD videos loading and playing right from the drive with no jitter at all.The design feels light but solid and it has a nice non slip coating on the back. I doubt I would ever clip it onto a pack or anything with the built in hole in one corner, but it speaks to the intent that this would be a goeverywhere device. It says that it is dust proof and water resistant, but there is no integral plug or cover for the USBC port which would seal up the internals nice a tight. If I were to take it into an environment where I might be expecting extra dusty or wet conditions were a possibility I would try to cover this exposed area.Al in all I am very happy with this drive as a really handy way to lug around a lot of data in a relatively rugged package, and its already been quite useful to me.

I am very impressed with this external SSD. When I read that it was NVMe NonVolatile Memory Express, I knew transfer speeds would be very good, but how NVMe drives are usually reserved for PCs with an M.2 slot on a motherboard, and that translates to extreme speeds. Turns out that when you pair an NMVe with the latest USB3.2 gen 2 standard, its not a bad combinationJust to get the nerdy stuff out of the way, USB3.2 gen 2 is rated for 10Gbps, which translates to around 1000MBs. That has got to be the fastest thing Ive ever had the pleasure of using out of an external drive. To give you context, you can move a 20 gigabyte file to and fro in 20 seconds There are some caveatsThe host that youre connecting to must support USB3.2 gen 2 as well.

Typically USB TypeC is associated with these speeds, but some hosts will only support USB3.1, which will not get you those top speeds. Perfect examples of this are my test cases a Samsung Galaxy Chromebook, a Samsung Galaxy Note 20 Ultra, and a custom PC. Each device was able to easily detect and use the Sandisk Extreme.The Chromebook supports USB3.2 with a USBC port, and I was able to see file transfers go balls to the walls. The Samsung Galaxy Note 20 Ultra, although a USBC port, only supported USB3.1 and I was getting half the speeds. Finally, my custom PC did not have a USBC port, so I had to use the included adapter to USBA in order to connect. Moving to USBA obviously brought the speeds down to USB3.1 specs.I know SanDisk makes a nonNVMe variant of the Extreme and pricing could possibly be lower, so its really up to you to either figure out what devices you currently have and if they support the latest USB3.2 gen 2 standard and go from there. You can also approach this from a futureproofing standpoint in the event that you end up buying new hardware that can achieve those transfer speeds.The drive itself is on the compact side with a rubbery back and a textured front, and the unit feels very solid to me. It has a loop to allow you to hook to carabiner or a safety tether, but you can get creative with it. SanDisk claims some level of water and dust resistance, and thats actually a very great feature to have if youre out and about. I think SanDisk hit it out of the park with this allinwonder of an external drive for the speeds and the tech that we can attain today.

The drive is backed by a nice 5 year manufacturers warranty. Seeing as how the Extreme NVMe drive is a USBC device, SanDisk is kind enough to throw in a female USBC to male USBA read old school square shaped adapter in the box in addition to the single mandatory USBC cable. I was a little disappointed in the length of the included USBC cable, and I estimate its about 68inches in length way to short in my eyes. If you plan on connecting this to a traditional tower or taller PCdevice it will be potentially dangling by the cable however if you use a laptop or have a top case mounted USBCUSBA port you should be fine. I cant help but feel this is one of those areas where a little more thought could have been placed by SanDisk to better suit a wider swath consumer devices even if I have to pay a dollar or two more to get a little more cable length as a result.As soon as you hold the SanDisk Extreme in your hand though, it just feels so cool literallyI guess that in large part due to the soft touch siliconerubberized coating that wraps around almost three quarters of the device. Only the topside facing portion of the drive is made of what feels like dimpledtextured plastic. The drive has a decent sized carabiner loop on the upper right side of the device, and only has a single female USBC port along the lower right corner. The whole unit feels light, yet satisfyingly well built at the same time to me. Sadly, I worry that as nice as the rubberized surface may appear, I have experienced significant wear on surface like this from other devices in the past. Its only been a few days of regular use, but I do worry about the longterm physical appearance over repeated travel and uses outdoors or on less than ideal surfaceenvironments. Additionally, it is for those reasons that I wouldnt want to actually clip this device on anything or anything onto it since I fear it will only wearscratchrub the coating off as well. As I just said so far so good, but only time will tell.Performance UsageThe Sandisk Extreme has performed flawlessly in all my file, image, and project transfers so far. I work with large Virtual Machine filesimages in addition to very large image files for webphoto design and development and I have to say that the SanDisk Extreme 1TB was a welcomed stepup from my current traditional 1TB2TB Platter USB hard drive setup I use to move around stuff from various workstations and personal machines. From a professional standpoint I was impressed how much performance increased the NVMe technology has increased file transfer speed and reduced file write times. The Extreme 1TB literally cut my transfer times by around 40 to 50 and that adds up when your transferring RAW image files or 20 Gigabyte VM files upwards of 40 times a day.I did note how WARM borderline HOT the Extreme 1TB can become particularly on large file transfers and interestingly stays mildly warm while plugged into a USB port. I cant help but wonder what a little more metal or heatsink consideration could be taken into place because I know for some people this may be a weaksticking point especially if your using it ina rugged outdoors setting, in hotter climates, during the peak of the warmer seasons. It does make for a nice hand warmer in a cold server room though Even on my large 20 Gigabyte transfer files as you can see in my photos I was still getting a respectable 400MB write speed, so to me thats greatWhile using it to transfer smaller batches of not professional grade images and documents at home for personal fun use I think the SanDisk excels more than anyplace else. It is formatted as a exFAT obviouslyso that it can be compatible with a wider range of consumer Operating Systems and devices but if youre working on Windows machines AND looking for more performance AND have a mind for enhanced securityfile permissionsystem administration like I do I suggest you format the drive for NTFS before you start to use it.Interestingly, and unsurprisingly the USBC female port has mange to build a small amount of lint and crud from being traveled with in my DaytoDay activities. I am not the most gentle with my portable drive to be fair so I cant say that there is anything inherently bad about the Extreme 1TB design other than potential cosmetic material durability concerns. While IP55 certification covers most accidental water accidents, this does not mean you can submerge the drive, or expect to survive a dip in the poollakeriver either. As nice as the Carabiner look I find myself a little perplexed to its inclusion for actual outdoors style activities. Especially because that USB port has no cover as I previously mentioned yes I know the device is mostly sealed and as I previously stated has IP55 dustshockwater resistance but call me old school and that doesnt mean your USB cables and device ports are necessarily certified that level either.Closing thoughtsI found it interesting that the device has no plug or dust cover for the USBC port on the drive itself. I cant help but think as rugged or portable as the device is that relatively inexpensive rubbersilicone dust cover would go a long way in preventing the amount crud andor pocket lint that ends up inevitably building up inside the female end of the internal port particularly after being placed in a bag or pocket. I really like the way the Extreme 1TB feels and looks in my hand or w I Just worry it wont look that way for long after a few months of being tossed in my photography bag, my gym bag, my pocket along with my keys, my backpack ..you get the drift. While the heat generated by the NVMe drive may be mildly off putting its been my experience that most NVMe drives get warm under usage. It would be nice if SanDisk maybe could a little more thermal consideration into the design perhaps a metal top plate instead of plastic. Regardless, SanDisk stands behind their products with a 5year warranty and I personally never had a SanDisk drive fail on me without cause.The SanDisk Extreme 1TB has knocked it out of the park where it counts most in my book performance. Its faster and lighter and takes up way less space than my older traditional USB platter disk drives you can see a photo of my older drives with a Nomad Case for comparison. The Extreme has convinced me its time to upgrade the rest of my older portable USB drives so that I can travel lighter, and spend less time waiting for things to get done be that for work, or just documents and image manipulation at home. I find myself now doing more in less time even if it is not as rugged as I though it should be.
