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: While technically not posting the best scores, the OCZ Vertex 3 Max IOPS drive is within a few points of the top scores which is certainly within the margin of variability in terms of benchmark scores. As always, the SandForce drives smoke this benchmark as it employs highly compressible data of which the controller takes full advantage.


This test employs compressible data showing the best case scenario in terms of data throughput for the SandForce drives. Let’s have a look at a few others that use incompressible data to see how that impacts the scores.

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: It’s easy to see that the Vertex 3 MI drive has some significant performance advantages over the other OCZ SF-2200 drives, especially in the small 4KB files. The Intel 510 is no slouch either in the reads but does trail noticeably in the writes.
