Intel 34nm X25-M Gen 2 SSD Performance Review

ATTO Disk Benchmark

Intel Completes Wind River Acquisition

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 2.34

OCZ Vertex Series 120GB

Corsair P256 256GB

The newly updated Intel X25-M Gen 2 drive shows a marked performance improvement over the original in the ATTO Disk Benchmark. In terms of read performance, the two drives are evenly matched, with neither having any real advantage. In the write tests, however, the new drive with the updated 34nm flash memory shows an approximate 31% performance increase, especially as the transfer size increases.
