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]
