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.

The 240GB Intel 335 Series SSD is four months older than the group leaders which average 13 months old. The hardware configuration consists of a Sandforce 2281 controller which is coupled with Intel's own 20Nm NAND flash. This particular combination is known to have relatively weak compressible write speeds, and the observed performance figures confirm this. With sequential peak and average read/write speeds of 510/234 and 367/209 MB/s the core performance profile is exactly as I would expect, very skewed in favour of reading over writing. With an overall effective speed of 434 MB/s the 335 is nearly 25% slower than the 533 MB/s group average. There are both faster and cheaper alternatives in the group test. [Feb '14SSDrivePro]
