LSI WarpDrive 300GB PCI Express SSD Review
ATTO Disk Benchmark
ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds 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 and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than IO response time, access latency etc. This test was performed on blank, formatted drives with default NTFS partitions in Windows 7 x64.

LSI WarpDrive 300GB
In ATTO testing, the LSI WarpDrive drive showed some of the highest overall read and write bandwidth of the five SSD solutions we compared here but only at certain transfer sizes. Furthermore, as you can see, there is a definite issue with transfer sizes of 128K and 256K. This is a known bug that we confirmed with LSI and they've noted a firmware update is coming that should resolve the issue, as well as bring the large 1MB - 8MB transfer speeds seen here, more in line with the drive's performance at the 64K mark.
