HDD Benchmarks: I/O Meter

I/O Meter Source: IOMeter

Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation, but since 2003 it was relaunched by the Open Source Development Lab. IOMeter can be used to simulate hard drive performance by specifying I/O operations to any physical drive.

PCSTATS I/O Meter settings were set to write to an 8GB sector of the hard drive with four outstanding IOs to simulate writing to an operating system. Each test was run for three minutes. Higher bandwidth (MB/s) and lower latencies (ms) are better.

Random 4KB read performance is a mixed bad for the Plextor PX-128M1S, with overall average speeds below that of the Seagate Barracuda XT. Average latency also ends up being about double that of the Seagate drive.

Write speeds fare considerably better for the Plextor PX-128M1S, with faster write performance and lower latencies. Small file write performance is critical to operations like application loading, so the PX-128M1S's high bandwidth and low latencies do quite well here.

Sequential read tests are also a strong suit for the PX-128M1S, and in limited-sector write tests it can actually exceed Plextor's speed ratings.

Sequential writes average our the speed of the Plextor PX-128M1S, with performance that's a little better than a conventional hard drive. Maximum latencies are also a bit better than a standard hard drive.
