If you wish to expand storage and reliably document HD, 3D, 4k, videos or shortburst photographs, consider SanDisk products. I purchased four of these about 5 years ago for a video project. They were compatible with my camera, which was used to record HD 4k videos. There was a lot of travel, one rough tumble with the equipment, and this product survived it all. It performed reliably at high speeds for the time and did exactly what it was intended to do. That being said, SanDisk offers better warranties and protections on their higher speed products. This offers more ways to recover projects from damaged cards. If you're recording or documenting valuable projects, I strongly advise purchasing a better protected product.

I work with many older adults who do not want to be left out of using helpful devices, yet appreciate a little bit more information to help them shop for an item like this one. So, if you are unsure of what you need then this is for you! Usually, if you take casual photographs then you do not need to purchase a Class 10. You can save money by getting a smaller class number, without noticing any difference in your photographs at all. Another way that you can save money is to use cards with smaller capacity (fewer GBs). If you strongly prefer trying to get all of your photographs onto one disk, then the 32 GB will probably allow you to do that, if you have been saving the photos in a format like .jpg. If you have been storing as .bmp ("bit-maps") then each photograph is a very large file, and that is OK, it just means that it probably isn't realistic to have them all on one SD card. The number of them that you would need will vary greatly depending on how many photos you take and save. In that event, get one card and see how many you can store. From that you will be able to estimate how many more cards you will need. Usually, it's best to purchase cards with a LOWER storage capacity. This suggestion is in case one of the cards is lost, so that you do not lose as many files or photographs along with it as you would if you had stored more on a large capacity card. It could be the difference between losing one photo album or your lifetime of photographs. These cards can also be used to store files on them. If you remember being told that there would be a paper-less office (which still hasn't happened), using these cards could allow you to achieve that at home, if you wish. A little thought will show that there is wisdom in keeping separate cards for your emergency information, recipies, estate planning, etc

Great value

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 ... MoreThe SanDisk Extreme PRO SDHC/SDXC UHS-I seems to be a standard affair for an SD card.

Their file recovery software is called RescuePRO Deluxe which is valid for up to two years.

[Rewarded Review] 5 Stars for BH - 2 Stars for SanDisk

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.

They encouraged me to purchase, test, and return if the in-camera speeds did not match what SanDisk claimed.Note: I've exclusively used SanDisk Extreme Pro cards for 15 years, and the reason for 2-stars is misleading specs.

[Rewarded Review] Apparently I wasted a lot of money on V90 cards

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.

[Rewarded Review] Fast, Reliable SD Card!

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.

[Rewarded Review] Great performance with consistent 0-100% write speeds

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.

[Rewarded Review] My favorite memory card

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.

its read & write speed different , not as per the shown photo and its A1 performance category.

"This seller is a fraud. The product photo and the delivered item are not the same, and even the model numbers differ between the photo and the product received. The specifications are also different. This is not the original model, and the packet arrived damaged, with a tear at the top corner. The packet is old and dirty. Do not buy this card from this seller." {Also note -at the provided photo & in the description different model numbers mentioned, the front face pic for A2 performance category Micro SDC but sent with A1 category, also in the photo, shown model number having 160 read speed but sent with 100 speed. So I was not looking for such card. }
