Crucial M4 256GB SSD Review (C400)
 

When Crucial released the C300 series of Solid State Drives last year they outperformed anything else available at the time. With read speeds around 340MB/s the Sandforce drives had a serious performance disadvantage, only offering around 280MB/s. The market today is in a very different state and the new SATA 6bps Crucial M4 has to compete against the stunningly good Sandforce 2281 controller featuring in OCZ, Corsair and ADATA drives.
