Fusion-io vs Intel X25-M SSD RAID, Grudge Match Review
The Setup, Methodolgy and SANDRA
Our Test Methodologies: Under each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark installations. The SSDs were left blank without partitions wherever possible, unless a test required them to be partitioned and formatted, as was the case with our ATTO benchmark tests. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system and waited several minutes for drive activity to settle before invoking a test.
On a side note, thanks to our friends at DV Nation for their assistance in supplying the Fusion-io ioDrive we used for testing. If you're looking for high end SSD storage, they're a good place to start.
Also, you'll note that we performed all of our SSD RAID testing with the Intel X25-M drives on an Intel X58 chipset-based motherboard via its ICH10R Southbridge SATA controller. This controller offered peak RAID 0 performance versus even the hardware-based RAID controllers we had in the lab for testing.
2 x Intel X25-M SSD RAID 0 - Write Performance
4 x Intel X25-M SSD RAID 0 - Write Performance
The Fusion-io ioDrive however shows a much less saw-toothed performance curve, with flat 650+MB/sec performance whether looking at read or write throughput. Looking at the graph, you can tell this technology means business and a sequential access pattern like a SANDRA benchmark run isn't going to saturate its throughput capability.
