Summary: Don't buy 256GB card expecting 140MB/s burst write speed in camera.Review: SanDisk is intentionally vague about the 140MB/s burst write speed for cards with 256GB or more storage. To their credit, they do state that 200MB/s read speed is attainable only with their proprietary card reader. They also list minimum sustained write speed as 30MB/s. But the way they advertise 140MB/s burst write speeds as shot speed is misleading. Quote With shot speeds up to 140MB/s the card is perfect for capturing the action as it happens, without missing a beatTested the card in Sony A7IV, Sony A1 (for JPEGs) and the in-camera burst write speeds were the same as a 128GB SanDisk card ~ 75-80MB/s (which is impressive, but nowhere close to 140MB/s)BH Support: I spoke with ... MoreSummary: Don't buy 256GB card expecting 140MB/s burst write speed in camera.Review: SanDisk is intentionally vague about the 140MB/s burst write speed for cards with 256GB or more storage.

Well, not wasted. I'm still planning to do some video on my Fuji X-T5, and V90 is definitely recommended for 6.2K. But I do mostly still photography, and after spending hundreds of dollars on 2 pairs of 128GB cards I'm still potentially running out of space at lengthy events. I read various online opinions on the use of V30 cards in the X-T5, and the consensus is that in practice, you can't tell the difference with V60 or V90 cards. I just did a couple of high-speed burst tests with these and yeah, once the buffer fills up there's a bit of a delay, but after a few seconds it was cleared. With the V90s I might be able to squeeze a couple more shots out on a long burst, but I really only ever do well-timed short bursts for fast action scenes anyway. Now, my camera ... MoreWell, not wasted. I'm still planning to do some video on my Fuji X-T5, and V90 is definitely recommended for 6.2K.

I really did not buy that because I never had any issues with SanDisk cards before. However if I use the same setup on standard SD cards I never have an issue, and I have shoot a Season of Hockey and Soccer without any issue. I can not say this is a problem with the card or the camera because I do not have another camera that supports these cards. I also do not have any other brand of UHS-II cards to try at this time.

This thing is a godsend for the things I use it for. I work in the IT department and used to carry around a portable hard drive to store the files I needed and now I just carry this little guy with me everywhere I go. I carry everything from ISOs for Office, Windows, and Dev tools to portable apps for Email, IM, and other utilities. Whenever I need to install something I just plug this in and mount the ISO and it installs way faster than using a CD or installing over the network. I did have to reformat the drive using exFAT so that I could store ISOs larger than 2GB but using FAT is the norm so it can work with OSx as well as Windows. SanDisk lists this drive as having a lifetime limited warranty on their website while Newegg only says 2 years. This means that if it ... MoreThis thing is a godsend for the things I use it for.

SanDisk lists this drive as having a lifetime limited warranty on their website while Newegg only says 2 years. This means that if it quits working for any reason they will replace it with a refurbished or new drive, unless the reason it stops working is because of physical damage. Nice peace of mind knowing this when youre going to spend 150. As far as design goes, the SanDisk Extreme comes in a metal case with a retractable USB plug. It is notably longer than the other drives I have used but not so much that becomes bothersome. The retraction mechanism works really well and is perfectly smooth and seems to be spring assisted and I much prefer this over using a cap to protect the USB connector as eventually you will lose that thing. The speeds on this thing are amazing, reading and writing files were on average around 200 MBs when copying to and from a Samsung 840 EVO SSD which is plenty fast for anything you need to do, installing programs from an ISO on the device finished within minutes.
I recently purchased the 64GB version of the card. While itclaims a read speed of 200MB/s, that requires a proprietary read mode which needs a card reader that they make, this also means that devices such as a camera will never be able to utilize those speeds.For my testing, I used a Transcend RDF8 SD card reader,which will not support their proprietary read mode, thus it will be only showing performance under the UHS I standard. This means reads and writes in the 80-90MB/s range. The primary goal of my testing was to determine the write speed consistency, since there are many cards on the market that will list a 90MB/s write speed, but in some cases, they will use low bin TLC or even QLC NAND, and you will end up with a card that will only maintain 90MB/s for ... MoreI recently purchased the 64GB version of the card.

If you only do basic tests such as crystal disk mark or ATTO, then such cards can score high but they will perform poorly as the card is filled.For the Sandisk Extreme Pro cards, all of the ones I have tried so far,including this one have used NAND where whether doing an initial write or overwriting non-TRIM NAND, they are able to maintain their advertised speeds from a 0-100% fill, which is what I look for in any card I purchase.As we can see from the benchmarks, the cards maintainedconsistent reads and writes without allowing down even as the card was filled.Overall this card is able to properly saturate a UHS I interface, and thus offer the full storage performance a UHS I device is capable of, especially cameras. PS, there is no benefit from using a USH II card in a UHS I slot.
The SanDisk Extreme PRO SDHC/SDXC UHS-I seems to be a standard affair for an SD card. The speeds are quoted at 200MB/s read and 140MB/s write. SanDisk Extreme Pro comes with Quickflow technology which optimizes the performance for quick exporting of files off of the SD card. The SD card is also great for recording 4K UHD video, SanDisk advertises this card can safely record 4K video without stuttering on playback. The speed of UHS-3 allows for taking high-quality burst camera shots.SanDisk Extreme PRO SDHC/SDXC UHS-I is stated to be resistant to shock, water resistant, impervious to extreme temperatures, and resistant to x-rays. This means that no matter what you throw at the Sandisk SD card it will last.

Whether you leave it out in stormy weather or you let it bake on the sidewalk, it should still work.The SanDisk SD card also comes bundled with recovery software which will recover any files that are deleted. Their file recovery software is called RescuePRO Deluxe which is valid for up to two years.
I have tried many cards to shoot in 4K on my canon R6, but this is the only one that has worked. This card gives you the speeds to shoot 4K very smoothly with zero buffering. While taking photos, there is no buffering when you are shooting. If you need a card to shoot 4K footage and no camera buffering, look no further and purchase this card. This card is now two years old and I use it daily for my photography business. The card runs smoothly as good as the day I bought it. The only con to this card is the price. When I bought it, it was a lot more money, so the price has gone down. With that in mind, I still think it’s worth the money as your 4K footage will film perfectly. 
As a rule I tend to stay with SanDisk memory cards. I have always found them to be reliable as proven by the SanDisk cards in my oldNikon D70 which I bought almost 20 years ago. I use two SanDisk 512GB Extreme PRO UHS-II SDXC memory cards in my Panasonic Lumix G9 II and they provide me with the ability to take 6007 high quality JPEG + RAW photographs (or over 10,000 JPEG photographs) per memory card.Each memory card also allows me to record video:ProRes format up to HD 60p 422HQ for 2h29mMOV format up to 5.8K 30p 420/10-L for 5h40mMOV format 4K UHD 24p 422/10-I for 2h50mMOV format 4K UHD 24p 422/10-L for 7h34mMOV format HD 24p 422/10-L for 11h21mMP4 format 4K UHD 60p 420/10-L for 11h21mMP4 format HD 24p 420/8-L for 47h08mThis is a V60 speed card (the ... MoreAs a rule I tend to stay with SanDisk memory cards.

Hard to add to reviews of a disk used by so many with so many reviews, both technical (bench tests even) and field-notes style.One of my go-to disks since I switched from CF card-based cams some years back. These and another brand not to be named, which sunk in quality. (OTOH, another good one so far, a bit pricier, are the Sony Toughs).I use these mostly in the 2-slot Fujifilm XT-2, where I have never yet had a Sandisk fail or disappoint. Fast enough I rarely face buffer time even with rapid bursts or short 4K video clips. While I've generally gone with 64GB as the maximum size (per the original manual recommendations), I just used this for a nature shoot, and.... flawless.No hesitancy to recommend (if it's compatible with what you use, of course)... still my ... MoreHard to add to reviews of a disk used by so many with so many reviews, both technical (bench tests even) and field-notes style.One of my go-to disks since I switched from CF card-based cams some years back.
