ADATA XPG SX900 256GB SSD Review
CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. It provides a quick look at best and worst case scenarios with regard to SSD performance, best case being larger sequential transfers and worse case being small, random transfers.
SandForce-based SSDs tend to do well in CrystalDiskMark, and wouldn’t you know it, the XPG SX900 fit the profile. It actually posted essentially the best scores in both read and write tests in the 512K data test (we’ll call it a virtual tie with the OCZ Vertex 450’s write score) as well as the 4K transfer test’s read score and the 4K QD32 write score.
