System Overview & Testing Procedures
Once we formatted the drive we can see that there is 119GB of usable space. Again this is a 0 provision drive so you get the total capacity of the drive. Normally on a SandForce-based drive that had 7% used for over provisioning you would get 111GB of usable space.

Opening up CrystalDiskInfo we can see all of the information about the drive. It supports S.M.A.R.T., APM, NCQ and most importantly TRIM.

For testing the drive we will be using the following benchmarking programs, we have provided links to each so you can run the benchmarks as well.
– HDTune Pro (download)
– Sandra Physical Disks Benchmark (download)
– ATTO Disk Benchmark (download)
– CrystalDiskMark 64bit (download)
– AS SSD Benchmark (download)
– Anvil Storage Utility Professional (download)
We also made these optimization changes…
– No power saving options in the BIOS
– ACHI enabled in the BIOS
– Windows 7 User Account Control (UAC) is disabled
– Windows 7 power saving settings are disabled
For comparison we will be testing the ADATA Premier Pro SP900 drive against these other solid state drives.

NEVER BUY ADATA PRODUCTs
Absolutely, this drive is a joke. My second sp900 Died after 1 month of NORMAL usage. I had to return the first one, because it was very slow. I was absolutely sure that the chips are fake. The retailer didn’t believe me however. They replaced it with another sp900 with 5.0.7a firmware with signature not even present at the manufacturers list. To prove my theory (that the drive is not even close with the ones from reviews) I had to open it. The board circuit inside had nothing to do with the ones reviewed. I’m absolutely sure that A-DATA did a marketing trick with passing some good ones for reviews and flooding the marked after that with crappy ones that not even use micron chips! Stay away from that junk!
