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 Neutron exhibits a slightly unbalanced performance profile favouring reads over writes, it achieved a real world score of 479.7 MB/s which is slightly above centre in the group test. The Neutron's ability to handle server loads as per the AS-SSD total score is also above average but weighed down by relatively poor sequential and 4k write speeds. With an above average price the Neutron doesn't represent good value for money. This drive uses a Link A Media Devices LM87800 controller, it's the first time Link A Media have produced a consumer grade SSD controller and although there have been no major issues reported so far, the company has a long way to go before establishing a reputation like Marvel, the company behind the controller on the Corsair Performance Pro, the predecessor to this drive and its better value for money GTX sibling ^{[Apr '13 SSDrivePro]}
