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]

We had high expectations for the Crucial M500. Crucial have a long history of producing outstanding Solid State drives. Both the RealSSD 300 and the M4, three and two years old, were almost legendary in terms of reliability and performance. The M500 falls far short of our expectations. The drive is relatively cheap and as such we were expecting to compromise on performance but the M500 just falls too far short. With a Real World Performance of 377.5 MBps which is in the bottom 40% and an AS-SSD score of 901 points (50th percentile) the M500 demonstrates relatively weak real world and average server performance. The M500 is competing with the Sandisk Ultra which manages to squeeze out significantly more performance despite sitting in the same price bracket. [Jun '13 SSDrivePro]
