SanDisk Extreme PRO 32 GB SDHC UHS-I Memory Card - Standard Packaging

When I travel I use a mid-range SLR (Nikom 610). I tend to not want to have to worry about space for copious amounts of photos, videos, and at the same time, speed for fast continuous shooting. This card is absolute top of the class (I've tested it out with ohter class 10/3 SDXC cards and this one outperforms in terms of how many shots I can rattle off in continuous high mode until it bottlenecks. Not even close. No Sandisk extreme card has ever failed on me despite at times challenging conditions. It is the rolls royce in my mind, so the only consideration I think for a prospective purchaser is if it fits your budget. If it does, I can't recommend it enough.

Dopo aver fatto i primi test in burst ed in trasferimento, sono rimasto deluso: le prestazioni di "scatto a raffica" sono esattamente identiche alla mia vecchia Sandisk Extreme III (30Mb/s), mentre quelle di lettura e scrittura sulla scheda da pc si discostavano di poco: Test con 1,9GB Mb -> lettura da Sandisk Extreme III: 1m 27s -> lettura da Sandisk Ultra Pro: 1m 27s -> scrittura su Sandisk Extreme III: 1m 50 -> scrittura su Sandisk Ultra Pro: 1m 33s Il motivo è presto spiegato: per poter arrivare a sfruttare i 95Mb/s dichiarati, la fotocamera ed il lettore di SDHC devono supportare l'interfaccia UHS-I: Così, convinto nel perseverare nel mio intento di sfruttare la super velocità della scheda, ho acquistato un SD Reader della Sonnet per MacBook Pro (si alloggia nella porta CardExpress), che sfrutta l'interfaccia UHS-I, ed ecco i risultati: -> lettura su Sandisk Ultra Pro: 37s -> scrittura su Sandisk Ultra Pro: 40s Insomma, il prodotto è ottimo, ma bisogna accertarsi di disporre di uno strumento che sia in grado di sfruttare la nuova interfaccia UHS-I. Con le fotocamere non UHS-I (che supportino le SDHC) è compatibile, ma va alla stessa velocità di quelle che trasferiscono 30/45 Mb/s (e costano la metà). La differenza di trasferimento delle foto è enorme nella copia su computer di sessioni di fotografia per chi, come me, scatta in RAW + JPEG. Come descritto sopra, l'SD Reader della Sonnet che ho acquistato per poter sfruttare l'interfaccia UHS-I della Ultra Pro si è rivelato un ottimo investimento per poter beneficiare di questa ultra-velocità; quando mi capita di utilizzare SD non UHS-I la lentezza nella copia di 5/6 Giga di foto è aberrante!

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 know this isn't a super exciting review, but this card just works and I think it was a good value.

I've bought this card after receiving my new digital camera capable of storing raw files. The trick was to find an SD card that wouldn't slow down the camera operation and at the same time wouldn't be unnecessarily fast and thus expensive. This one serves it's purpose very well. With the capacity of 500+ full resolution photos, including RAW, it allows me to forget about the card while shooting. And then, importantly, it's very quick to move the files from the card to my PC (the real world transfer rate is 80+ MB/s). I'll probably fetch another one when I go for holidays, to be able to shoot for more than a couple of days. (Don't forget: bigger cards are nice, but if a flash-memory device fails, you loose all your data. So it's better to have a couple of memory cards rather than one big one.)

Simply super fast and enough space. I get 1700 RAW shots 24MBs each on my Nikon D 5200. Don't buy cheaper ones and don't buy lesser capacity ones. Having such faster speed this card enables camera to shoot more frames on continuous burst mode (RAW). Having huge space means you don't need to carry laptop when you travel to transfer images. Also when you are recording vidoe you need not to worry about filling the card too fast. It works perfect and does what it is supposed to do.
