Customer Comments

The Class 10 16GB SD at 30MB/s is good for almost all amateur cameras. It works great with my D7000 as a secondary card for JPG and HD videos, to the UHS-I SD 16GB Extreme Pro at 45MB/s.
Since the write speeds are good for both these cards, I do not have to worry about the buffer overflow in Continuos shooting, with both these, I can take 20 in RAW and JPG.
I would recommend the SD 16GB Extreme Pro at 95MB/s for Sports or Action Photography.

After realising I needed something bigger than my current 8Gb card for my DSLR, I started looking around for 64Gb cards at a high read/write speed of at least 20Mb/s. I found a lot of these cards were expensive, 32Gb cards were asking for around £40 and above and the cheapest 64Gb cards were well above that, apart from Play.com where this card was going cheap. Pleasantly surprised but knowing it's always better to shop around, I compared the card on Play to the card on Amazon and found Amazon to be a few quid cheaper. The product itself is excellent, recording full 1080p HD video at 25fps from my DSLR with absolutely no problems for long periods of time. Fully recommended and at value I cannot find anywhere else.

Firstly, this is an SDXC card thus you need a card reader (whether built-in a laptop/desktop, etc.) or device (camera, music player, etc.) compatible with it. For some readers there may be a firmware update to bring SDXC support but that is rare. If it does not work - it's likely your hardware does not support SDXC.
Performance Test: 38-40MB/s read (sequential, sustained), 10-12MB/s write (sequential, sustained) - thus meets Class 10 rating (10MB/s write sustained).
Should this qualify for the "Ultra" name/moniker though? I would expect somewhat faster write speed for an "Ultra", there are many class 10 cards out there. (I do have an 32GB HP class 10 card that outperforms this one for example)
I do have an issue with the "30MB/s* transfer speed" displayed on the card; some people might think it means 30MB/s for both read and write! I personally find that somewhat misleading, why not write "30MB/s read, 10MB/s write"? Transfer is not just read from but also write.

OK, it does say "class 10" but since there are no higher SD speed classes even knowledgeable people may think it exceeds class 10 rating and writes far faster than 10MB/s.
All being said, SanDisk have always been reliable for me, performance meets or exceeds rating and price is now competitive thus overall I think it still deserves top marks.
