The Sandisk Extreme was once a good choice of SSD thanks to its extremely (pun intended) competitive price. In terms of performance the Extreme would of course obliterate any regular hard drive but at 16 months old the Extreme can no longer compete with more recent SSDs. In terms of typical consumer workloads the Sandisk delivers below average performance and is even less capable when it comes to server workloads scoring a total of just 761 on the AS-SSD benchmark. The weaknesses in performance are a consequence of the now dated Sandforce SF2281VB1 controller which delivers sub-optimal compressible transfer rates. The best thing the Sandisk Extreme has going for it is that its successor, the Extreme II, was just recently released. ^{[Jun '13 SSDrivePro]}

The 250GB Crucial BX100 SSD is the value orientated variant of Crucial's M range of SSDs. The BX100 uses the same NAND as its premium MX200 sibling but the BX100 uses a Silicon Motion controller as opposed to the Marvel controller found in the MX range. Feature wise the BX100 is missing SLC caching and there is no hardware encryption (so security frameworks such as windows Bitlocker will operate less efficiently). In terms of I/O performance the BX100 looks promising. Comparing the BX100 and MX100 shows that the newer BX100 may be faster than its predecessor but as yet there are insufficient user benchmarks to draw any definitive conclusions. The BX100 has only just started hitting the shelves so there's plenty of room for price reductions from its already reasonable price tag. I will revisit this review when I have more performance data for the BX100. ^{[Jan '15 SSDrivePro]}
