The 128GB Samsung 830 is nearly two and a half years old which puts it at a significant disadvantage to more recent models. With peak and average sequential read/write speeds of 512/323 and 410/239 MB/s it's not too shabby, especially considering its age. The sequential figures actually match the current group leaders. The small file 4K peak and average read/write speeds of 22.5/60.3 and 17/40 MB/s are not as impressive and lag the group leaders by 50%. Reduced small file performance weighs on the 128GB 830's effective speed which is 376 MB/s and 20% lower than the average of 453 MB/s for the highest voted group leaders. Finally comparing the 128 and 256GB versions shows that the larger drive has a superior performance profile, which is not uncommon for SSDs but newer models from Samsung don't share this trait. [Feb '14 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]
