OCZ Technology Vector 256GB SSD Review

OCZ Vector 256GB - ATTO


ATTO is a disk benchmark which allows testing of drives with a range of file transfer sizes from 4K up to 8192K.  We ran tests with a 1GB span and a default queue depth of 4, which would simulate a fairly intense work environment.  The data read and written from ATTO is able to be compressed, which is something that the venerable Sandforce controllers thrive on, and asynchronous NAND doesn't have much trouble keeping up with synchronous in compressible transfers. With our newcomer Everest 2 controller we expect the results to be interesting.

The Vector essentially matches the highest 512K and 1024K (and higher) for maximum read and write throughput, we see the Vector peaking sooner (beginning at 128K).  We also see much more balanced read and write performance in 4K transfer file sizes while not necessarily battling for maximum transfer rates, although the read speeds are the fastest we've tested by about 17%, which is a strong advantage for OS-predominant file sizes.
