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]

MORE DETAILS

This is the first solid state drive to feature OCZ's in-house Indilinx Barefoot 3 (IDX500M00-BC) controller and what a debut it proved to be. OCZ still use third party memory (Intel Micron Synchronous 25nm MLC) so unlike the Samsung 840 Pro the Vector is not built 100% in house. There have been several SSDs released recently, each slightly besting the other in some small corner of benchmark space. First the Corsiar Neutron GTX, then the Samsung 840 Pro and now the Vector which currently holds the crown for sequential write and 4K write. In terms of overall performance the Vector achieved a real world speed of 578.8 MB/s and an AS-SSD score of 1243 both are spectacular results that firmly place the vector amongst the top two or three performance SSD's currently available. In terms of raw performance the only alternative is the Samsung 840 Pro[Jun '13 SSDrivePro]
