Western Digital VelociRaptor 1TB 2.5″ Hard Drive Review

CrystalDiskMark is a small HDD benchmark utility for your hard drive that enable 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)

We know that CrystalDiskMark always gives a slightly lower speed in comparison to AS SSD sequentially, however we also look at the 4K results. Marked against other mechanical drives we see over double the performance from both 4K and 4K 32QD tests.
