The Sandisk Ultra Plus has an above average consumer performance profile and is available at a fantastic price. It's one of the cheapest SSD's we have reviewed and we like it a lot. With a real world speed of 488.1 MB/s and an AS-SSD Total score of 910 points, the Ultra Plus is able to handle consumer workloads reasonably well and enterprise workloads just below average. The slightly below average server performance is primarily due to the Ultra's deep queue 4k write speed which clocked in at just 165 MB/s, considerably below the group average of 241 MB/s. Given that this drive is only a few months old, there is a good chance that its prices will drop even further which would make it an even better value consumer proposition than it already is. [Apr '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]
