Crucial, best known for their memory products, was the first to put an SSD on the market with a 6Gbps interface way back in early 2010 with the C300 drive. Back then, we ran some tests and found it to be impressive when compared with what was on the market at the time. Since then, a lot has changed and there are a number of 6Gbps interface drives on the market now so competition is definitely stiffer this time around. Will it hit them mark using the same controller with firmware and NAND updates? Read on and see.

The Crucial m4 SSD will be available in several capacities from 64 GB to 512 GB and all should be available this month although pricing is MIA at the moment. Our 256 GB drive rated for up to 415 MB/s reads and 260 MB/s writes which is a little behind that of the Intel 510 Series drive which uses the same Marvell controller - although the m4 utilizes eight channels while the Intel uses ten. Obviously, the firmware employed by each differs and the benchmarks will bear out how they perform in comparison...
