The 275GB Crucial MX300 supersedes the MX200. Unlike its predecessor, the MX300 is TLC based and therefore suffers from weak write speeds in comparison to MLC drives. The MX300 utilises a sophisticated algorithm to enable fast burst write speeds provided that there is sufficient free space on the disk but as the drive fills up write performance drops to the relatively poor levels seen on other TLC drives (similar to mechanical drives). At current prices (70 USD) the MX300 competes well with other low end drives such as the OCZ Trion, Adata SP550 and Samsung 750 EVO. As stocks build the MX300 is likely to see further price cuts, so it could become a very interesting value proposition. See the current value leaders here[Sep '16 SSDrivePro]
