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 250GB Crucial MX200 is successor to the hugely successful MX100. Both drives use the same NAND and controller but the new MX200 features Dynamic Write Acceleration (DWA) which is a new dynamically sized SLC cache. Samsung were the first to introduce SLC caching on the 840 Evo nearly two years ago so Crucial are somewhat late to the party. SLC caches generally only help performance in corner case real word scenarios and benchmarks. I prefer drives without SLC caches because they offer more consistent and sustainable real world IO. Comparing the MX100 and MX200 shows that the newer MX200 has a significantly faster peak write speed which is of course explained by the new DWA cache. Price is the deciding factor between the MX100 and MX200 so although the MX200 isn't priced aggressively yet, it will almost certainly move up the value rankings when retailers build stocks and subsequently cut prices. [Feb '15 SSDrivePro]
