Capacity Capacity			120GB			128GB

The 120GB Evo, like its 250GB sibling, features a second level Turbowrite cache (TWC). This 3GB block of high speed SLC memory allows the Evo to write data at 370 MB/s, nearly double its normal rate. When the TWC is full write speeds drop by around 50% but since consumers generally write less than 3GB in a typical write operation, the performance drop will rarely be noticed. On the other hand, in a server environment this sort of performance degradation would be unacceptable. Comparing the 120GB and 250GB Evos shows that they have similar performance profiles. The performance equivalence between the different capacities, coupled with the fact that their prices are almost linear, implies that both capacities represent roughly the same value for money. Within its TWC, the 120GB Evo is capable of chart topping burst IO rates and it sits squarely amongst the best performing 120GB drives. ^{[Aug '14 SSDrivePro]}

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]}
