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]

The 256GB Samsung 850 Pro is the fastest consumer SSD we have seen to date. Thanks to Samsung's new 3D V-NAND the 850 Pro has lower power consumption and better performance, albeit marginally, than both the 840 Evo and 840 Pro. Looking at the benchmark figures for the 840 and 850 Pros shows that the effective performance improvement is 10% whereas the 850 Pro beats the 840 Evo by 16%. These drives effectively saturate SATA 3.0 making it difficult to distinguish between them in day-to-day use. At current prices the 850 Pro is prohibitively expensive, prices need to drop by 15% before it approaches the 840 Pro from a value perspective. Samsung may release a value orientated 850 Evo soon, but for now "most" users are better off with the 840 Pro. [Oct '14 SSDrivePro]
