Benchmarks
To test the SP900, we put it up against a comparable SATA III SSD as well as a low-end SATA II SSD over a range of different benchmarks to get an idea of what kind of performance you can expect.
Anvil Storage Utilities

| SP900 | Crucial m4 | Kingston SSDNow |
Anvil is a good overall benchmark that gives results in MB/s and IOPS for both read and write. As you can see, the SP900 performs significantly worse than the m4 across the board. Even the m4’s known-lousy write speeds beat out the SP900’s, and the read speeds just get blown out of the water.
AS SSD

AS SSD tests using incompressible data which provides us with a “worst case scenario”. The numbers for the SP900 match up with the AS SSD results claimed on ADATA’s website. When compared to the m4 though, the reads are very underwhelming.
ATTO

| SP900 | Crucial m4 | Kingston SSDNow |
If AS SSD provides us with a “worst case”, then ATTO would be our “best case” because it uses fully compressible data. Whenever you see manufactures claim huge numbers (such as with this SP900) they are usually pulled from this benchmark. Looking at the 2k, 4k, and 8k tests, we can finally see where those 500+Mb/s numbers came from. The SP900 pulled 567Mb/s read and 539MB/s write, actually higher than the claimed numbers. But you have to remember, these numbers mean very little for real world performance.
CrystalDiskMark

| SP900 | Crucial m4 | Kingston SSDNow |
CrystalDiskMark is another good benchmark for getting an overall idea of a drives performance. Like in AS SSD, the SP900 again struggled with the incompressible data, giving similar results. The numbers are across the board pretty low, especially the read speeds which again are crushed by the m4.
HD Tune

| SP900 | Crucial m4 | Kingston SSDNow |
Unlike the other benchmarks which just give averages, HD Tune gives us insight as to exactly what the drive is doing with its graph. The SP900 actually performed better than the m4 in this test, with a higher average, and burst rate, and lower access time.
Raid-1 vs Raid-0 there I saw data as very important and donbuilg the failure rate was not something I wanted to do.My SSD really blows your raid-0 out of the water when we talk about reads and the more random they become the better. Although I’ve read crystal disk mark isn’t the best for testing drives anyways just the easiest to do.
