Crucial’s M500 SSD hit high marks for capacity and price but failed to attract performance users back to the Crucial brand. Armed with Crucial’s 20nm process with 128Gb dies, the M500 helped to change the SSD landscape that led to the current 50 cents per GB price point we enjoy today.
The 128Gb Micron dies worked well for the two largest capacity sizes, 480GB and 960GB, but hurt performance on the two smaller capacity sizes, 120GB and 240GB. This time around, Crucial increased parallelism on the smaller capacity sizes by moving to 64Gb dies. This doubles the number of dies and increases overall performance.
