This review is from: ADATA 16GB Class 10 Micro SDHC Flash Card Model AUSDH16GCL10-R
Cons: This is the third time I've had to send an ADATA card back for replacement.
The first one just failed and would not read/write. The second one would do the same thing intermittently, and I lost a ton of phone photos.
This third one would not be recognized by any device from time to time, and it would show up as a removable floppy... Also incurred data loss.
I just got the the replacement, and my camera would not record HD video to the new Class 10 card, so I tested it on my computer.
Why am I NOT surprised that the Write speed bogs down on start-up to 0.1 MBytes/sec, and then it averages 6.5 MBytes/sec.? That would be OK if this was a C6 card, but it's not, it's a Class 10. So what gives?
Other Thoughts: The card I just got back from ADATA as an RMA exchange had the package opened, but it came with a sticker that says "ADATA Quality Control Tested" I don't know what they tested, this card is defective to no end!
Their RMA process is archaic where you have to receive a Word Documents, fill it out manually, save it, and email it back to them for an RMA number. That coupled with the fact that I am not sure I'd get a working card, makes me not want to spend the $2 to send this back for a replacement.
This is the LAST time I ever buy or use any ADATA products. If they offer them for free, I'd still have to think about it.
Pros: Large capacity, small form-factor, included USB card-reader (with strap), and best of all a TRUE CL10.
Cons: It didn't do the laundry upon delivery by the USPS.
Other Thoughts: I test all of my μSDHC/SDHC cards upon arrival. Recently, I received another one (from different mfr.) that averaged the rated speed, but the built-in controller hiccuped on first access thus making the first write at about 2MB/sec before jumping up to CL10.
That is NOT the case with this card! This card tested at a very respectable 17 MB/sec. read, and 11 MB/sec write speeds. The best part is that the range in write speeds was right in between 9 and 13 MB/sec. the whole time. To me that means that it never have that one bogged-down write that will kill what you're trying to do.
P.S. Before anyone complains... The card's capacity is 32,000,000,000 (billion) bytes which most systems will read as 29.x GB. Yes it sucks, but that's just the way most mfrs. do it these days.
Pros: It was well priced with a rebate, and it's got the Patriot name printed on it.
Cons: HD Speed tested it at 6.9 MB/sec. which is really just a class 6.
Other Thoughts: I actually have a Sandisk Class 6 SDHC card that tests faster at 8.4 MB/sec.READ FULL REVIEW
