The 840 Pro is stunning. Samsung have created a completely in-house package including both the controller and their own new 21nm toggle mode NAND. On release (Oct '12) this was the fastest performing deep queue depth consumer grade SSD available. Fast forward six months (Apr '13) and the 840 Pro still holds both the random read/write deep queue depth speed records of 384 MB/s and 326 MB/s, impressive considering how fast the SSD space tends to move. There are no obvious weaknesses, in-fact the 840 pro takes first place in nearly all of the speed categories and is only seriously rivalled by one drive, the OCZ Vector. To conclude, in terms of both outright performance, particularly server orientated, and value for money the 256GB and 128GB 840 Pros are amongst the top handful of drives currently available. ^{[Jun '13 SSDrivePro]}

The Plextor M5 delivers fantastic value for money and sits within easy reach of the top handful of SSD's currently available. The M5's performance favours server type workloads where it takes joint fourth position in the AS-SSD total score benchmark. With a Real World Speed Index of 524.5 it will also cope very well with consumer workloads. Aside from its blistering performance we also like the fact that this drive uses the latest Marvell controller which hasn't suffered any of the reliability issues that plagued some of the early Sandforce based drives. When this drive first hit the shelves in September '12 it was overpriced but since then prices have dropped by nearly 40% making it currently one of top five value for money drives available. ^{[Jun '13 SSDrivePro]}
