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 128GB Adata Premier Pro SP900 has peak and average sequential read/write speeds of 496/166 and 175/106 MB/s. The average speeds are significantly worse than peak which indicates that the SP900 has an unstable performance profile. Additionally, the peak write speed of 166 MB/s is 90% below the group leaders. In terms of small file 4K read/write speeds things are a little better where the SP900 achieved peak and average scores of 23/83 and 17/29 MB/s. These 4K figures still lag the group leaders by around 40%. The Overall effective speed for the SP900 measures 340 MB/s, the worst I have seen to date on a 128GB SSD. The SP900 is not particularly well priced, and therefore represents poor value for money. There are both faster and cheaper 128GB alternatives available amongst the group leaders. [Feb '14 SSDrivePro]
