ADATA Premier Pro SP920 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)

Unconditioned

Conditioned

Like ATTO, CDM gives us a set of lines that stay close to flat across the spread of data collected. Consistent performance figures are key to a strong drive.

Drive Comparison

For the purpose of drive comparison I use the performance figures from both unconditioned and conditioned tests with 0% data fill.

Unlike the results within ATTO, the real world speeds are a little down on those expected however as mentioned on the individual drive metrics, the 920 gives us it’s best fresh out of the box and just as we would expect from an array of synchronous NAND packages.
