Capacity Capacity			60GB			128GB

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]}
