Crucial M4 256GB Solid State Drive Review

Testing – Sandra Physical Disks & Anvil
Sandra Physical Disks benchmark is built into SiSoftware’s Sandra software suite. It tests drive performance and gives you a drive score and random access time.

Good results on both tests, right up to the specifications.

The next test is Anvil Storage Utilities, which is a really great piece of software.  It is still in its beta stage, but we are very impressed.  The SSD benchmark gives you scores for both read and write as well as a combined score.


We used Anvil’s threaded I/O test to benchmark IOPS.  The block size was set at 4k and the queue depth was set at 32.


Now since there is such a big difference between read and write speeds on this drive we tested read and write IOPS separately.
