SanDisk Extreme Pro 64 GB SDXC Class 10 UHS-1 Flash Memory Card 95MB/s SDSDXPA-064G-AFFP

Customer Reviews:* I haven't done any computer benchmarking or anything of that sort with this memory card. I don't believe that those sorts of tests reflect real life use, since a sequential read/write is relatively uncommon, and you're never writing bunches of tiny files all the same size. I have found, however, that real life performance is beyond what I am able to put this card through.I am using this card with a Sony NEX-5N, which is a compact system camera (mirrorless camera) that writes 16.2 megapixel images in a few different levels of JPEG compression and a Sony RAW format. In addition to RAW images, it also records video in MP4 or AVCHD format at 1080p 60fps. I have used this card to the absolute top performance limits of this camera. It allows me to record 1080p60 AVCHD (28Mbps bitrate) with no hiccups or stutters. I can shoot in burst mode for short spurts, and while this card is not going to magically soak up 10 6MB JPEGs per second, I can get about 10 shots in one second and let the card catch up with the image processor's buffer in a couple of seconds. At this time, no card is capable of writing fast enough to keep up with 10 16.2MP images per second, though, so there is no reason to expect it in this card.I can pull the images off this card fast enough that I don't even notice that I'm actually dealing with a block of flash memory instead of a hard drive. I use Adobe Lightroom to import the images, so I'm not sitting there waiting on a Windows File Transfer dialog. I get to deal with a more pleasing interactive file transfer/import by using Lightroom, so I don't have to sit and twiddle my thumbs, but I'm impressed by the speed that files appear in my photo library on import. I believe that anyone who is going to "benchmark" this card with a full HD video camera or a DSLR will be very pleased with their purchase. I can't speak for people who will use the card for file storage/transfer, but my guess is that those users won't be disappointed either. * I have reached advertised speeds on a built-in card reader and a newer digital camera but there are a few things anyone should know when choosing a card.Cards with 32GB or less are SDHC and should work with most devices released in the last few years. SDXC will cover cards with higher capacities, such as this card in 64GB. This is an important consideration to Linux users since SDXC uses exFAT which may not work with your OS. If you have an up-to-date Windows installation or a recent Mac release you will be fine without third party software, though a firmware update may be necessary for your card reader if it's pre-'09.You will not achieve UHF speeds on a USB 2.0 bus - you will see a maximum 20-30MB/S depending on file size and other factors. On many host devices the speed gains are negligible during operation because of fast internal memory buffers - I can burst (9/s) an average of 15 shots in RAW+jpeg on my DSLR with a class 6 card, or 18 with this - so probably not worth the premium price for that gain alone. Video there is no difference since the class 6 can float the 20mbps required for 1080i on my camera. In other words, if you can get the extreme pro in 64GB for the same price as the extreme in 128GB, your money is probably better spent on the extreme, if not on a non-UHF card, which is to say class 6 or 10.It may be noteworthy that this card is waterproof and x-ray proof, but does not specify that it is magnet proof as other brands' documentation does. That said, Sandisk has some of the most robust built-in error checking features in the 'biz and other brands don't really compete in quality if you do some research.My advice is to make sure you can use the extra speed you're paying for - if you don't have a USB 3.0 card reader, a host device with USB 3.0 PC connection, or a built-in card reader on a laptop that's either newer or has a recent firmware update, you may be wasting a fair sum of money here. Also make sure your device says SDXC if you do go above 32GB. Many devices' documentation will explicitly say that it works up to 32GB. It'll just try to format the card over and over if you feed it an SDXC.Hopefully some info here was helpful! Happy hunting
