Average Bench: 75.5% (546th of 1058)

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]
