Crucial v4 (256GB) Reviewby Kristian Vättö on November 22, 2012 1:01 PM EST
Performance vs. Transfer Size
ATTO is a great tool for quickly measuring performance at different transfer sizes. The v4 performs similarly to the m4 connected to SATA 3Gbps port in the read test but its write performance is poor between transfer sizes of 2KB and 64KB.
