Plextor M5 Pro Xtreme 256GB Solid State Drive Review

CrystalDiskMark

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)

When we look at the CrystalDiskMark results and more particularly the 4K speeds, we can see how the use of Toshiba’s latest 19nm NAND packages and in particular the use of extra dies greatly improves both the read and write speeds – especially when the queue depth is ramped right up to QD32. The sequential speeds are also very impressive with very little loss found from the speeds recorded within ATTO.
