    Fast read times, write speed is a bit below the Extreme 45MB/s card, 24 Dec. 2014

    I’ve a good range of SD cards and have tested most of them to date, I vary the brands as it makes it easier for me to find cards that are empty or that I use with specific cameras.

    This Sony card is a UHS-I class, so can take advantage of some devices that support this protocol (it’s fully backward compatible with non UHS cameras etc). The headline figure though is only for the read performance which can be a little misleading for some buyers. The card is far from slow overall, but it’s a bit behind the SanDisk Extreme 45MB/s offering in terms of in camera write speed. It is though quite a lot faster for reading and file transfer so weight up what your requirements are first.

    I benched the Sony card using a USB 3.0 card reader and using software I got close results from real world file sizes (video and photo) to the benchmark I ran.

    Read speed: 87MB/s
    Write Speed: 38MB/s

    A bit of variation from test to test (a few MB/s either side) on paper the Sony is near enough to it’s claimed max speed for reading files. The Extreme 45 MB/s does write a bit faster though (over 45MB/s as indicated and it hits that speed for read times too) Really it comes down to what you need.

    If you need faster in camera speeds (which most do) then the Extreme 45 MB/s is quicker, if you want even faster speeds then the 80 MB/s is the one to go for (that card writes a lot quicker than both) super speed demons might want the Extreme Pro series or equivalent offerings.

    The Sony isn’t a slow card when compared to a normal class 10 quite a lot faster really, and does have the advantage of a toughened casing which is less prone to damage being waterproof, x ray proof, shock proof just like the Extreme range offer. Warranty is a bit less than I’d like at 5 years Sony should really increase that to come into line with rivals. There is a newer version of this card out (and it’s evidently even faster) As it is if you transfer big files a lot this is fast, it’s quite fast in camera too just not as quick as some other offerings. That doesn’t make the Sony a bad card but it would be a lot more helpful if they just told you what the speeds for both were.

    Worth a look at the right price if it’s quick enough and you need some protection from rough handling or the environment.

    Not that impressed!, 18 July 2012

    I’ve had this card a little while now but I’ve only just recently had chance to really try it out & put it through its paces. I initially tested it’s speed capabilities using my laptop & it’s built-in card reader. I carried various Read/Write tests (timed with a stop watch) with different file types, quantities & sizes. I also carried out the exact same tests with my Sandisk Extreme 45mb/s card to compare. After disappointing results from this card but not knowing the specifications of my built in card reader and whether it is fully UHS-1 compatible, I carried out various similar tests with the cards in my Sony A77 Camera, which is UHS-1 compliant. The results again were very disappointing. I found that the Sandisk is slightly quicker at writing (the most important to me) than the Sony card, and only very slightly slower at reading than this Sony Card too!
    My advice is if you’re going to be using this card in a fast camera, don’t waste your money on this card, get the Sandisk Extreme. It’s half the price and just as or slightly faster than the Sony “so called” 94mb/s card.

    Write speed 14MB/s, read speed 16 MB/s, 11 Jan. 2015

    I’ve used one of these cards in my Sony A6000 for a few months, which isn’t enough to ascertain its long-term reliability, but is enough to see how much of a read / write speed-boost it could give over the Class 6 Fuji card I had been using. The A6000 is capable of shooting at up to 11 frames per second, but the images couldn’t be written to the old card quick enough to take full advantage, producing something of a `stutter’ after 10 or so shots.

    With a stated write speed of 45MB/s (the 94 MB/s denotes the read speed), the Class 10 Sony should be some way faster than the Fuji, although the reality is a bit different. Using the h2testw speed test program, I managed to get a write speed of only 14MB/s and a read speed of just over 16 MB/s. While the read speed isn’t overly important to me, the write speed was quite disappointing, at less than one-third of stated. Of course the proof of the pudding is in the eating, but I have to say that I really can’t see much difference, if any, between the Sony and my old Fuji card in my A6000.

    On the plus side, the Sony card seems reliable and I’ve had no problems with it in my camera since I bought it, but the same could be said of pretty much every SD card I’ve bought. In short, it’s a good enough card but don’t believe the stated read / write speeds and don’t rely on them if you need a fast card. This begs the question, do all SD card manufacturers exaggerate their card speeds or is this one just particularly exaggerated?
