At just 5 months old the Intel 530 Series SSD is the newest SSD in the group test. Unfortunately the 530 uses the same basic formula we have seen going back two and a half years. Sporting a Sandforce 2281 controller coupled with 20nm NAND flash the performance profile struggles with incompressible data and predictably favours reads over writes as with all the other Sandforce 2281 drives we have seen. With peak and average sequential read/write speeds of 498/154 and 454/131 MB/s the 120GB Intel 530 lags the group leaders by 50%. Small file 4K peak and average performance clocked in at 34/101 and 26/76 MB/s which is slightly above average for a leading 120GB SSD. There are faster and cheaper alternatives available in the group test. [Feb '14 SSDrivePro]

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]
