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]
