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.

ATTO Disk Benchmark - Read/Write Performance
Version 2.41

WD SiliconEdge Blue


Micron RealSSD C300 (SATA 3G)


Intel X25-M Gen 2 160GB

OCZ Vertex 120GB

Read speeds for the SiliconEdge Blue were just a notch behind the X25-M and Vertex drives according to ATTO, but were well behind the C300. WD's drive pulled well ahead of the X25-M in terms of write performance, however, it still lagged behind the others.
