Crucial’s BX300 SSD is a 3D MLC entry level SSD, with debut pricing in line with the Samsung's 850 Evo, the current market leader. The BX300 is one of the faster consumer SSDs available, with a 2% performance improvement over Crucial’s older MLC based MX200 and a 25% performance improvement over the TLC based MX300 which are both from Crucial’s more expensive MX product line. MLC NAND offers more consistent performance and has higher endurance than TLC NAND. Although Samsung’s 850 Evo (which is based on proprietary TLC V-NAND) has a 10% effective speed advantage over the BX300 the BX300 wins on write consistency. The 240GB BX300 has a three year warranty or 80 Terabytes Written (TBW) compared to five years or 75 (TBW) for the 250 GB 850 Evo. This makes for an interesting choice between the BX300 and the 850 Evo. Each model has an SLC cache which is proportional to its capacity, as a result the larger capacities offer better performance. The 120 GB BX300 has a 4 GB SLC cache, the 240 GB has 8 GB and the 480 GB has 16 GB. SLC caches improve burst write performance beyond the already respectable MLC write performance. Unfortunately, at least for now, the BX300 only comes in modest capacities, with the largest being 480 GB. For write consistency, thanks to its MLC NAND, the BX300 punches well above its price point.

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]
