The 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer. [Jun '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]
