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 '14SSDrivePro]
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]
