Crucial M4 512GB SATA 3 SSD Review – ATTO Disk Benchmark and Crystal Diskmark

ATTO DISK BENCHMARK 2.46

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications.  For our testing, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb.  Manufacturers prefer this method of testing as it deals with raw data rather than random or mixed which, although more realistic, result with lower performance results.

The manufacturer specifications list high sequential performance as 415MB/s read and 260MB/s write and we can see here that they reached that and them some.  This is a nice start to our evaluation.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill) or random data. We will test here with random data as it is the closest synthetic equal to real life use in this software.

The high sequential benchmarks are again confirmed but the thing we like about this test is the 4k random write score of 105MB/s.  As many know, this particular disk access method is in use more than any other and also the primary method responsible for the visible difference we see when upgrading from the hard drive.

The Crucial M4 512GB SSD now becomes top dog on the block with the highest result we have seen to date.  Formerly, the OCZ Vertex 3 was the only to break the 100MB/s barrier.
