The 256GB Transcend SSD370 sports a Silicon Motion (SM2246EN) controller coupled with Micron 20nm synchronous MLC NAND. With peak sequential read/write speeds of 520/290 MBps and peak 4k read/write speeds of 29/116 the SSD370 has an effective speed which is amongst the bottom 25% of ~250GB drives. The effective speed is weighed down by a relatively weak sequential write speed of just 290 MBps. The performance highlight for the SSD370 is its ability to deal with mixed 4k IO which is arguably one of the best real world indicators. At current prices the SSD370 can't compete as there are both cheaper and faster alternatives on the market but prices are almost certain to drop at which time the SSD370 will fare far better in terms of value. [Oct '14 SSDrivePro]

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]
