Benchmarks
Anvil Storage Utilities
 |
 |
 |
| SX900 | SP900 | M4 |
Anvil is a good overall benchmark that gives results in MB/s and IOPS for both read and write. Our SX900 was able to score an impressive 422 MB/s read and 172 write for sequential data, putting it well ahead of the lower end SP900 and just behind the Crucial m4.
In the nonsequential tests, it performed slightly worse than the m4 in reads but significantly better in writes. The SP900 isn’t even close.
In the IOPS tests the SX fell behind the m4 and SP900 on reads, but completely blew them away on writes.
AS SSD

| SX900 | SP900 | M4 |
AS SSD is another good benchmark which really stresses incompressible data, giving us a “worst-case” scenario. On the spec sheet ADATA claims 470 read, 180 write for this test. Our SX900 was able to pull 458/134 which is pretty close to the claimed, but again falls short of the m4 in both read and write.
The lower-end SP900 performed much better in writes, but much worse in reads.
ATTO

 |
| SX900 | SP900 | M4 |
If AS SSD provides us with a “worst case”, then ATTO would be our “best case” because it uses fully compressible data. This is the benchmarks that gives out the huge numbers that manufactures love to throw around. ADATA claims the SX should top out at 555/530 and it comes pretty close with a 545/521 max, blowing away the m4 but getting slightly beat out by the SP900.
CrystalDiskMark

 |
| SX900 | SP900 | M4 |
CrystalDiskMark is another good benchmark for getting an overall idea of a drives real-world potential. Like most of the other tests, the SX900 traded blows with the Crucial m4 and blew away the SP900.
I’m in the market for a new SSD. Going to check out this SSD. Looks great for the price.
