Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 - since then it got wide spread within the industry. Meanwhile Intel has discontinued to work on Iometer and it was given to the Open Source Development Lab (OSDL). The project is now driven by an international group of individuals who are continuously improving, porting and extend the product.
Iometer version 2006.07.27 was used for testing and while we tested a dozen different file sizes we will be looking at the ones that are important to Windows users. In the Microsoft Windows operating systems many of the transactions are done at 512B/4kB/8kB/32kB/128kB, with the vast majority at 4kB, then 128kB / 512B, then the rest. Very few Windows applications use transfers larger than 128kB. We began the test by filling the drive completely full of data first and then testing 100% random IOPs in a 4KB region. We set the queue depth to 32 for this test.
Read Performance in IOps
Benchmark Results: IOMeter showed that the OCZ Vertex LE and Vertex 2 Pro basically had once again the same level of performance. The OCZ Vertex LE had slightly better performance at the 4KB and 16KB file sizes thanks to firmware enhancements that have been done on the Vertex LE SSD. Even with the improved firmware the Vertex LE fails to compete with the Intel X25-M Gen2 160GB SSD or the Crucial RealSSD C300 256GB drives as they read IOPS on both of those drives are insane.
Write Performance in IOps
Benchmark Results: When it comes to write performance is is clear that nearly all of the drives have been optimized to perform best at the 4KB file size. The OCZ Vertex LE had great performance at the 4KB file size and was only slower than the Intel X25-M and Crucial C300 in the 512 Bytes test.
