The Crucial 256GB m4 SSD comes now with an improved firmware and we now get read speeds up to 500MB/s sequential. Compared to the SandForce offerings, the m4 comes with a good price/performance ratio, so we could afford getting higher capacity SSDs. The tested model also comes with a Data Transfer Kit composed of hardware (USB to SATA adapter) and software (EZ GIG IV Cloning Software).
