Capacity Capacity			128GB			256GB

The Crucial 128GB MX100 has the smallest capacity and is the slowest of the MX100 range. Comparing the 128GB and 256GB MX100s shows that the 256GB version has a 75% faster write speed. Within the MX100 range write speeds scale linearly with capacity, as a consequence, the 128GB version struggles to compete with similarly priced drives from other manufacturers. On the other hand, the 512GB version and to a lesser extent the 256GB version offer far better value for money. Overall the MX100 has an effective speed which is amongst the top 30% of 128GB drives so its not bad by any means but there are however both cheaper and faster alternatives available in the now extremely competitive 128GB SSD category. ^{[Oct '14 SSDrivePro]}

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]}
