The 256GB Transcend SSD370 sports a Silicon Motion (SM2246EN) controller coupled with Micron 20nm synchronous MLC NAND. With peak sequential read/write speeds of 520/290 MBps and peak 4k read/write speeds of 29/116 the SSD370 has an effective speed which is amongst the bottom 25% of ~250GB drives. The effective speed is weighed down by a relatively weak sequential write speed of just 290 MBps. The performance highlight for the SSD370 is its ability to deal with mixed 4k IO which is arguably one of the best real world indicators. At current prices the SSD370 can't compete as there are both cheaper and faster alternatives on the market but prices are almost certain to drop at which time the SSD370 will fare far better in terms of value. [Oct '14 SSDrivePro]

The 250GB Crucial MX200 is successor to the hugely successful MX100. Both drives use the same NAND and controller but the new MX200 features Dynamic Write Acceleration (DWA) which is a new dynamically sized SLC cache. Samsung were the first to introduce SLC caching on the 840 Evo nearly two years ago so Crucial are somewhat late to the party. SLC caches generally only help performance in corner case real word scenarios and benchmarks. I prefer drives without SLC caches because they offer more consistent and sustainable real world IO. Comparing the MX100 and MX200 shows that the newer MX200 has a significantly faster peak write speed which is of course explained by the new DWA cache. Price is the deciding factor between the MX100 and MX200 so although the MX200 isn't priced aggressively yet, it will almost certainly move up the value rankings when retailers build stocks and subsequently cut prices. [Feb '15 SSDrivePro]
