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]

This drive is another victim to the Sandforce 2281 controller's relative inability to handle incompressible data. The performance profile shows superb sequential read ability but relatively very poor sequential write and 4k read scores. With a real world speed of 371.4 MB/s and an AS SSD total score of 779 the MAX IOPS version of the Vertex 3 is below average by today's standards and there are significantly better deals available elsewhere. [Feb '12 SSDrivePro]
