Fusion-io vs Intel X25-M SSD RAID, Grudge Match Review
ATTO is a more straight-forward type of disk benchmark that measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes over a total max volume length of 256MB. This test was performed on blank, formatted drives with NTFS partitions.

Fusion-io 160GB ioDrive
ATTO shows a very similar performance progression for the Intel RAID arrays, whether using a two or four drive installation. Read performance is in the mid to high 500 or 600MB/sec range for the Intel RAID arrays but higher in the instance of a four-drive setup. Write performance with the Intel-based RAID 0 arrays again pretty much doubles from going from two to four hard drives. In addition, obviously, small block transfers from .5K to 4K are not a strong suit for the SSD. In any case, the performance graphs for the Intel RAID arrays are impressive.
And again, the Fusion-io drive shows flat-lined read and write performance, this time within the 800MB/sec territory. Also again, the performance bars scale so linearly, it's as if at each point on graph, the Fusion-io drive is maximizing throughput from its NAND Flash array to its fullest potential.
