OCZ RevoDrive Review: SSD RAID + PCI-Express

ATTO Disk Benchmark


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.

When comparing ATTO results, be advised that the Revo's performance is graphed against a theoretical 1000GB/s performance scale on the x-axis. That makes it more difficult to visually compare the results from the other drives--we'd recommend eyeballing the actual values. 


 
 


 
 


The C300 is far and away the fastest drive when we're moving very small amounts of data. Above 2K, however, the drive's overall performance begins to flag. Its Read Test throughput is significantly higher than the F100, but its write throughput doesn't scale at nearly the same rate. The C300 ties the GSkill for second place in terms of read performance, but is last in writes.

ATTO is another clear sweep for the Revo; the drive's read performance is a massive 90 percent higher than the GSKill Phoenix, its closest competitor. The write speed gap is smaller--but "just" 44 percent faster seems plenty fast to us.
