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]

The review for this is poor considering that it is faster the Samsung Pro/Evo etc through extensive testing. The Drive is the fastest out there. See review: http://www.tweaktown.com/reviews/6471/sandisk-extreme-pro-240gb-ssd-review/index10.html
