The Intel 330 is just under two years old and sports a Sandforce 2281 controller coupled with Intel's own 25nm MLC NAND. This combination typically produces a performance profile that struggles with incompressible data and favours reading over writing. With peak and average sequential read/write speeds of 514/138 and 414/122 the Intel 330 is unable to compete in today's market and falls over 50% short of the group leaders which manage peak sequential read/write speeds in the 500/300 MB/s region. Small file 4K peak and average speeds are better and clocked in at 32/89 and 24/63 MB/s which is 10% below the group leaders. Overall the 330 has an effective speed of 370 MB/s which makes it one of the slowest 128GB SSDs I have seen to date. [Feb '14SSDrivePro]
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.
