Interesting review, sadly yet understandably reviews never examine the range issues that can arise in everyday usage, and consequently how something that begins relatively small can grow to be an absolute killer for what would otherwise be a good and very competitive product.
Case in point. I read ADATA had released driver updates back in February. I have a SX 900 64G I use for benchmarking. After downloading and running the 525 FieldUpdater it was obvious that no matching driver was included in the newly released 525 driver update package I had downloaded despite the SX 900 being on the list.
I emailed tech support and didn't receive a reply for 7 days despite the confirmation of receipt stating a response would come in 1 to 3 days. I did get a reply after a posting the issue to their Facebook page in which I was told "Please see the attached for the signature file you needed for the firmware update as it took us some time to obtain it from our headquarters"
Indeed a matching 525 FieldUpdater driver had been included in this email and I installed it.
The result was something to see, erratic and downright wonky, come to mind. A malfunction in the installation I presumed and so I downloaded the ADATA software suite SSD Tool which wouldn't and couldn't Security Erase the disk. Parted Magic was then installed and did the job allowing me to clean reinstall the driver I'd been emailed and hopefully resolve the erratic performance issue. In part it resolved erratic reads and writes but now every ATTO write above the 128k mark had lost 40% of its performance capability from the benchmarks using the previous driver.
Support were emailed including ATTO screen captures, and their response was to send it back for replacement.
_Wait a minute just sent me the old driver I stated in my response
Can't "After consulting with our headquarters, it’s confirmed that once the firmware is updated, it cannot be removed or fallback to the older version".
Having no choice I hinted that as this debacle had originated with them that an upgrade from 64G would be an appropriate compensation for the enormous waste of time, and additional costs I was incurring.
The disk was packaged and insured then sent to ADATA for a cost of 20$ and it should be noted that locally this additional $20 represented the retail difference between a 64G and a 128G capacity.
Tracking informed me ADATA received the disk in 5 days and later confirmed by them. Once the 3 to 5 days turn over stated by them came and passed and on day seven a status inquiry was sent and 6 hrs later, confirmation a package to me had been put in the hands of mail services.
That was March 21 and I received the disk 11 days later April 1st in my snail mail box no signature required (a less scrupulous person could easily exploit that).
The round trip experience total is six weeks with a dollar output of over 20% of the sticker price the disk was purchased for. Total time wasted on their error, fiddling with downloads installing and removing ADATA brand software that didn't accomplish the required tasks (additionally the Acronis suite that was packaged with the drive never successfully completed the key transaction on their site) research, installations removal... ya'll get the picture.
Does the SX 900 perform well/competitively... all the published reviews and accompanying benchmarks hold true, so yes it's a cracker even in the 64G capacity.
Would I recommend it?
Only to a tech masochist with tons of time to waste as well a a few bucks.
Now you have a more complete picture.
