The Evo is remarkable in that, like the Sandisk Extreme II, it features a second level cache. For the 250 GB Evo this consists of a 3 GB Turbowrite cache (TWC) which is a block of high speed Flash Memory. When the TWC is exhausted write speeds drop by approximately 50% but that won't often happen under typical consumer workloads. In terms of raw performance, even with its cache, the Evo still isn't the fastest drive. With a real world speed index reading of 439 MB/s the EVO is however, within reach of the two speed leaders (Vector and 850 Pro). At a price point of $130 the Evo is around 30% cheaper making it the best value for money SSDs I have seen in 2014. Comparing the Evo and the Sandisk Ultra Plus shows that the Evo is the winner but the Sandisk may be a viable alternative thanks to its cache-free, and therefore more consistent performance during extended writes. [Aug '14 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]
