We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: AVADirect, GIGABYTE, Cooler Master, LSI and Noctua.
You can read more about TweakTown's Storage Product Testing Workstation and the procedures followed to test products in this article.
We changed our SSD performance charts up in one of the articles last week at the request of the article sponsor and I like the changes so we are keeping them for a little while. Now, instead of just listing the last ten to twelve drives reviewed we have chosen some of the more popular drives and controllers.
Represented in the performance charts will be the sample drive we are testing, Intel X25-M (G2), Indilinx Barefoot via the Corsair Nova, Marvell SATA 6Gbps via the 128 and 256GB Crucial RealSSD C300, SandForce SF-1200 via the 120 and 240GB OCZ Vertex 2 and finally the fastest consumer platter drive Western Digital VelociRaptor.
ATTO Baseline Performance
Version and / or Patch Used: 2.34
ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.
In ATTO we see that OCZ's claims of 285MB/s read and 275MB/s write speeds are accurate. The 4K write speed is right around 130MB/s, the Vertex 2 with the 4K High IOPS programming is able to achieve close to 180MB/s in that block size. It has been quite awhile since we have tested a drive without the High IOPS programming so it will be interesting to see how the Agility 2 measures up to the Vertex 2.
