Crucial M4 256GB SSD Review (C400)

Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0 x64.


A fantastic set of results for the Crucial M4, scoring over 410MB/s in the sequential read test and 238 MB/s in the 4k QD32 write test.

With incompressible data, the Marvel controller inside the Crucial M4 powers out way ahead of the Sandforce 2281 drives.

When compressible data is enabled via the ‘oxoo fill’ setting, the performance of the Sandforce drives outclass the Marvell unit (see 3 images above). The scores for the Crucial M4 256GB don’t change much, if at all, with this setting enabled.
