The Sandisk Ultra Plus has an above average consumer performance profile and is available at a fantastic price. It's one of the cheapest SSD's we have reviewed and we like it a lot. With a real world speed of 488.1 MB/s and an AS-SSD Total score of 910 points, the Ultra Plus is able to handle consumer workloads reasonably well and enterprise workloads just below average. The slightly below average server performance is primarily due to the Ultra's deep queue 4k write speed which clocked in at just 165 MB/s, considerably below the group average of 241 MB/s. Given that this drive is only a few months old, there is a good chance that its prices will drop even further which would make it an even better value consumer proposition than it already is. [Apr '13 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]
