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]

Comparing the 150 to the original Vector is disappointing, the newer 150 actually offers marginally worse performance than its predecessor. A strange result but verified (at least partly) by figures on OCZ's own website: 100K 4K read IOPS for the Vector vs 90K 4K read IOPS for the 150. The newer 150 comes with a 5 year warranty which covers 50GB/day vs. the original Vectors 20GB/day but even this should be taken with a pinch of salt considering that the OCZ stock price is currently trading at around seven cents per share, an all time low. Despite the fact that new Vector 150 performs worse than its predecessor it's still a very competent performer and if prices drop, it has the potential to become a decent value proposition. In the meantime however there are far better deals available elsewhere.  [Dec '13 SSDrivePro]
