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]
