The Crucial M4 is one of the oldest SSD's to have made it into the group test. When it was released its primary competitors were Sandforce based drives which suffered from two major problems: reliability and weak incompressible data performance. As a result this drive was one of the top drives of its time. That was back in Apr '11. Today the M4 is no longer able to compete and scores below average (377.9 MB/s) on the Real World Speed Index benchmark and way below average (676) on the deep queue depth orientated AS-SSD Total score benchmark. Of course these figures are still far faster than any mechanical hard drive and owners of this drive should feel in no hurry to upgrade. People looking to make a new purchase will find much better value elsewhere. [Apr '13 SSDrivePro]
