ATTO & Iometer Synthetic Benchmarks
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.
ATTO – Intel P67 Platform
Benchmark Results: We certainly see the Vertex 3 living up to the 550MB/s reads and 525MB/s writes specifications, hitting and exceeding both on this benchmark. This is pretty much double of what we saw with the previous generation SandForce drives and above the original RevoDrive.
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: The 512KB read and write scores really showcase the strength of the Vertex 3 while the 4KB random writes shows something altogether different.
