Average Bench: 55.6% - 554th / 836

Based on 6,033 user benchmarks.  Models: M4-CT128M4SSD2, M4-CT128 M4-CT128M4SSD2, M4-CT128 M4SSD2, M4-CT128M4SSD1, M4-CT128 M4SSD1

The 128GB Crucial M4 is almost three years old, an extremely long time in SSD land. With peak and average sequential read/write speeds of 500/194 and 429/185 the 128GB M4 matches the group leaders at reading but lags by 60% at writing. Comparing the 128GB and 256GB versions of the M4 shows that the two drives have a very similar performance profile. This suggests that both drives have the same number of NAND channels which bodes well for the smaller capacity drive as a lot of other drives exhibit slower writes speeds in the smaller capacity varieties. Small file 4k peak and average read/write speeds measured at 27/87 and 21/52 MB/s which is only 13% below the average of the nine user voted group leaders. Considering its age the M4 is a very impressive drive but there is far better value for money available in today's market[Feb '14 SSDrivePro]

Upgraded to the M4 on my 9yr. old HHD pc about 2.5 yrs. ago and the slow pc boots in 11 seconds. Newer SSDs are now available at better values. Bottom line, update your HHD to SSD and squeeze more life out of old pcs.
