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 MX100 is the first 16nm SSD to date. Aside from NAND, the MX100 shares the same hardware as its more expensive sibling, the M550. Comparing the MX100 and M550 shows that the two drives have similar read speeds but that the MX100 lags by nearly 50% at writing. The newer 16nm NAND reduces costs and accordingly the MX100 is the cheapest SSD (per GB) to date. In terms of performance the MX100 is a compromise which may or may not be worth making depending on individual circumstances. For typical desktop use including email, office documents and web browsing the MX100 is a great choice but power users should look elsewhere. Comparing the 250GB 840 EVO and 256GB MX100 shows that for a marginal premium, the Evo offers better write speeds. (Note: at 500GB they are more evenly matched) [Jun '14 SSDrivePro]
