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]

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]
