OCZ Vertex 3.20 240GB SSD Review

CrystalDiskMark is a small HDD benchmark utility for your hard drive that enables you to rapidly measure sequential and random read/write speeds.

Here are some key features of “CrystalDiskMark”:

• Sequential reads/writes
• Random 4KB/512KB reads/writes
• Text copy
• Change dialog design
• internationalization (i18n)

Like AS SSD, CrystalDiskMark sees a gain in performance. Looking at the 4K sectors this time the read speeds are up by 4MB/s from a standard Vertex 3 to a shade under 36MB/s, whilst the write speeds are up considerably from 87MB/s to just under 140MB/s.
