For this review Crucial has sent over one of their newest solid state drives, the 256GB MX100. Crucial presently offers three series of SSD - the M500, the M550, and the MX100 - and oddly enough the MX100 series generally fits in between the M500 and M550 when it comes to read/write performance and price. In this review we will see just what you can expect from a drive that Crucial touts as offering "cost-effective mainstream performance".
