OCZ RevoDrive X2 Review: Killer SSD Performance

Article Index

ATTO Disk Benchmark

ATTO is a more straight-forward 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.  This test was performed on blank, formatted drives with default NTFS partitions in Windows 7 x64.

OCZ Vertex LE 100GB SSD

Fusion-io ioXtreme 80GB PCI Express SSD

OCZ RevoDrive 120GB


OCZ RevoDrive X2 240GB

In ATTO testing, the RevoDrive X2 drive showed some of the highest overall read and write bandwidth of the five SSD solutions we compared.  Like the IBIS drive, small file transfers are not the RD X2's strong suit, but when you get up to 16 - 32K and higher, the product really begins to stretch its legs, besting even the Fusion-io drive by a significant margin from 32K to 8MB transfers.  The ioXtreme does offer significantly more responsive small file transfer results however.
