PNY Elite Performance 64GB High Speed SDXC Class 10 UHS-I, U3 Up to 95MB/sec Flash Card - P-SDX64U1H-GE

Bought this card and used it off and on for over 10 years. Its a work horse! The transfer speeds are decent for past standards but in 2025 this device is not considered fast although not too slow when considering in camera transfer speeds for photo. I have only a few experiences of corrupted data and im not sure if it was the card or not. I look for PNY if I can't get, or can't afford SanDisk.

DESCRIPTION> A very good price (I paid Amazon about $8) for a 16GB Class 10 SD Card> Formatted easily in my camera, no problems reported> Comes with a nice tiny compact case which is only 1 1/2" X 1 1/4" x 1/8">> The tiny case is important because space is very tight in some camera bags---you could even carry it in your wallet>> The tiny case is also a "big deal" since low-price SD cards often come without cases.> The white space at the bottom of the card is writable, if you need to label the card---a good feature missing from many SD cards. It is best to use a felt-tipped markerRECOMMENDATION> Buy a cheap reader so that you don't have to plug your camera to your computer, for example eForCity SDHC / SD / MMC Memory Card Reader to USB 2.0 Adapter, Smoke for only $2 with free shipping.> Many devices will not work with SD cards over 32GB, so check before buying larger cards.> I've found that in practice, 4GB or 8GB SD-cards work best for photos. I purchase 16GB cards, I try not to use over half the capacity. Why?:>> If a card fails, or you loose your camera, you loose everything. I've never experienced a total card failure, loosing all my data, but I have had cards malfunction, loosing several photos, and taking 30 seconds or so to write an image to the card---in which case, just changing to spare card is the best option.>> If you loose a card, you loose everything. I lost a card when I dropped a camera, which opened and the card fell out.>> 4GB or 8GB loads into my computer MUCH faster with no hassles.> Although my camera will take large SD cards, I've found that even 16GB overwhelms my computer, especially when it is set to display thumbnails. It can take 15 minutes or so to create the 2000 or so thumbnails. It is generally faster to set your computer to display a "list" rather than thumbnails, then download all the photos, and let your computer generate thumbnails from the files on your harddrive.> If you can, download every day's photos at the end of the day--as insurance against card failure and to keep the downloads fast. It is also a good idea to label your photos as soon as you can so that you don't forget details. You don't need to erase the downloaded photos from your SD Card--the card can serve as a backup. Indeed, at the current low prices of SD cards, it makes sense to never erase photos, and instead just keep the SD cards as backups.> Class 10 are high speed SD cards. Class 10 is much faster than I need for photographic purposes. My camera will take standard HD videos with Class 4 cards. But you do not sacrifice anything by using faster cards, and the faster cards may make a huge difference when uploading/downloading to slow devices, such as tablets.WI-FI> If your camera can download by Wi-Fi, beware that it may take an hour to download 16GB of photos and create thumbnails. So again, set your computer to display a "list" rather than "thumbnails" when downloading.> Note that if your camera isn't Wi-Fi, you can buy SD cards with built-in Wi-Fi, for example Transcend 16GB Class 10 SDHC Flash Memory Card (TS16GSDHC10E)> Click on “Stoney” just below the product title to see my other reviews, or leave a comment to ask a question.

In my testing using this for one week only it works flawlessly. It is just as fast as my 58 dollar 95MB/s transcend extreme pro cards in both read and write. If this card holds up it is the best value out of the last 6 different brand cards I have tested over the last week.As long as this card gives me longevity and I have no reason to believe it wont, it will be the only card I buy until another company breaks the 80 MB/s barrier( I find none of the cards actually ever stay in that 90 Mb.s area after I use them for awhile, not sure why that is) or San Disk reduces their card price to match this at 50%. Plus, unless Canon can make use of these fast cards I hardly see the need, my digic 5+ processor still cant keep up with the card at 7 frames a sec.This card handles my new Canon 70D with ease,the camera buffer seems to fill before the card, so I just don't see a need for anything better. Wondering if a firmware update can increase that in anyway if the future or if it is a hardware limitation on the caner itself?For now this is the best bang for the buck I have found at 24.00! Right now you can get almost 3 of these for the same speed and equal San Disk 95 MB/s card. The prices just went up on San Disk to 67.00! Amazon usually has them at 57.00 and once I saw them at 54.00, but never near 24.00 like this PNY! I only wish this card came in the same speed in the 64Gb size, I never knew how fast I could fill up 32 GB until I started using Raw/Jpeg setting on a DSLR.Here is the transcend the only other card in my personal tests on my computer that equals this card in read and write speeds. I say my computer at my home, that's all I can go by:SanDisk Extreme Pro 32 GB SDHC Class 10 UHS-1 Flash Memory Card 95MB/s SDSDXPA-032G-AFFPNOTE I changed the word Transcend to SanDisk everywhere in the above post, I mis-wrote my initial review.UPDATE After using it for a week 4 hours plus a day:Okay after using this card more I like it a lot. BUT, even though the testing results show it to equal the Sandisk card, in reality, on my camera(canon 70d), doing what I do, the Sandisk simply "feels" faster, ever so little, but faster.My camera also seems to give me a busy slightly more often using this PNY card than when I use the Sandisk.So for me I rate the Sandisk the best I have ever used with this a close second. Now if I factor in cost this PNY is the best by far, but if money is no object I feel the Sandisk is better. On a 100 point scale this PNY is a 95 and the Sandisk a 100. And again, the Crystal mark testing does not bear this out, this PNY and the Sandisk are neck and neck in the test program. But when using the camera itself, if only my perception of the cards, the Sandisk is better. Now will I buy another Sandisk, probably not, at this price, for me, this is the card to have. If you simply just want the best cost not a factor get the Sandisk I linked to in the original post.I hope someone else can get both cards and post their experience with them to compare to my experince.
