This is Seagate's third foray into the the SSD market and it's clear from the specifications that Seagate haven't taken any chances. The 600 incorporates the now reasonably established LAMD LM87800 controller coupled with 19 NM Toshiba MLC, a very similar combination to Corsair's Neutron GTX. This combination of hardware coupled with Seagate's custom firmware produces a very solid set of performance figures. With a Real World Performance rating of 531 MB/s and an AS SSD total score of 1131 the Seagate 600 demonstrates both superb server and consumer performance capabilities. The pricing on the 600 is currently around average for a group leading SSD and likely to drop with time as the 600 is still relatively recent. Overall the 240GB Seagate 600 represents good value for money and delivers great performance. [Aug '13 SSDrivePro]

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]
