The Crucial/Micron M500 Review (960GB, 480GB, 240GB, 120GB)

Performance vs. Transfer Size

ATTO is a useful tool for quickly measuring the impact of transfer size on performance. You can get the complete data set in Bench.

These charts give us a great look at the various graduations of performance as we scale up NAND die count within the M500 family. The 480/960GB drives perform identically, while the 120/240GB drives show significant steps down in max sequential read performance.

Write speed is a bit closer between all of the M500 capacities, but none approach the peak performance of Samsung's 840 Pro.
