I benchmarked this PNY card upon its arrival, using the "Flash Memory Toolkit v2.0". Its read speed is consistently high at 14-18MB/s. But its write speed is strongly dependent on the file size:
- For smaller files of 2-5MB, its write speed is very poor at just 3-5MB/s
- For larger files of 10-15MB, its write speed improves to about 8MB/s
(See the performance chart I uploaded to 'Customer Images' section for details)
Next, I tested the same card using "H2testw v1.4". This program measures the sequential read/write speed for 1GB files. Under this test, the PNY card achieved write speed of 9.5MB/s and read speed of 18MB/s.
I repeated the above tests on two different computers using two card readers, and obtained consistent results. Just for reference, I have previously benchmarked the PNY Professional 16 GB Class 10 SDHC Card (P-SDHC16G10-EF) under identical conditions. It was able to achieve write speed of 13.6MB/s and read speed of 18.5MB/s. So the problem is not with my setup.
For a card to be marketed as 'Class-10', it must be able to deliver a MINIMUM write speed of 10MB/s. This PNY micro-SDHC card, however, can only achieve a MAXIMUM write speed of 9.5MB under best-case scenario. In other cases, such as when used in a digital camera (file size around 3-5MB), this so-called calss-10 card actually performs slower than a SanDisk class 4 microSDHC SDSDQM-032G.
It appears to me that PNY has loosen its definition of 'class-10', in order to market this micro-SDHC card at a higher price. An even more disturbing observation is that: this practice seems to be a growing trend among memory card makers. Case in point:
- The Kingston Digital 16 GB Class 10 SDHC Card SD10G2 performs much slower than Kingston 'class-4' card when used in a digital camera.
- The SanDisk Ultra 16 GB 6 SDHC (SDSDRH-016G-A11) was called a 'class-4' one year ago. But now the same Ultra card is marketed as a 'class-6'. Although to be fair, the old Sandisk Ultra card actually performed better than most other brands of 'class-6' cards.
I despise deceptive marketing claims, therefore I cannot recommend this PNY 'class-10' micro-SDHC card.
[Update on Dec 2, 2011]
I double-checked the PNY card using another program (CrystalDiskMark v3.01). The result is actually worse than my previous finding. For sequential writing of huge files (500MB) it only reached 8.65MB/s. See my newly uploaded chart in 'Customer Images' section for details.
I've been using it for several Years.
No File Degredation/corruption.
Never failed to read/write any information.
I use it with my Contour Roam helmet Camera, which requires a class-10 Memory Card.
The Big Card, is not a separate memory card, it's an ADAPTER.
That way you can use Either the Small Card, or put the small one Into the Big One, and it still reads/writes data flawlessly.
While its maximum performance isn't as awe-inspiring as those cards that claim to read 150MB/s (and later admit to only being able to write 10MB/s!), this card is far more consistent. Linear read speeds are about 55MB/s, random large block reads about 43MB/s, and small block read speeds in excess of 4MB/s by themselves are pretty good. This card also sports linear write speeds of 37MB/s, random large write speeds of over 7MB/s (most cards I have tested get less than 1MB/s here), but the small block random writes are more congruent with other SD and MicroSD cards I have tried, at about 1MB/s. Unlike some other cards, though, I do not see long stalls from this card under mixed read/write loads, and writing large sets of files (mostly 1MB to 100MB) manages to average over 10MB/s.
I'm in Southern California, grew up with 80s heavy metal and well, now, where I live, such a station simply does not exist any longer on the radio. Sad, but true. (Metallica fans, anyone?) Say hello to more modern technology. I've got probably 120 CDs in my collection, just more or less collecting dust, as I do not have a CD player anymore, and well, I'm kinda too lazy to keep changing CDs, anyway. Plus, listening to the same band for an hour gets kind of boring.
So, I ripped all of my CDs, deleted the crap, and the total came to about 25 GB. I then plugged my phone into a Coby CA-747 Dual Position CD/MD/MP3 Cassette Adapter and it worked in my car stereo like a charm. I'm still tweaking the sound a bit because, well, it's obviously not the same quality as a CD, but it's better than what I had. My van's stereo did not have an Aux jack, so I needed a tape adapter.
For what I use it for, who knows if, 1, my phone even utilizes the Class 10 transfer speeds or not, and 2, if simply playing an MP3 negates the use a Class 10 speed device. I'm not one to nit pick here about that, but I feel that I got what I needed out of this thing, and I'm happy.
