Crucial M4 / Micron C400 256GB SSD Review

ATTO & Iometer Synthetic Benchmarks

ATTO v2.41

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.

Benchmark Results: The Crucial m4 scores well here although it trails both the similarly equipped Intel 510 and SandForce based Vertex 3 drives in reads and writes. Even so, it exceeds the rated specifications and it’s a very nice improvement over the C300.

Iometer 2008 (1.1.0)

Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation who has since discontinued work on Iometer and it was ultimately turned over to the Open Source Development Lab (OSDL). We chose the file sizes that best reflect many of the Windows transactions. 4KB random read/writes is very common on every day user machines. Large sequential writes represent large file copies. The drive block size is 512kb so it should give a very good indication of peak performance. We set the queue depth to 4 for the tests as generally Windows operations tend to happen at queue depths of 5 or less.

Benchmark Results: We finally see another drive crank out the 4 KB random read numbers we saw on the Vertex 3 drives and the write scores are better than that of the Intel 510 Series but slightly behind the Intel 320 Series.
