In today's market the only thing the Mushkin Chronos has going for it is the fact that it is an SSD and as such considerably faster than a regular hard drive. Compared to other SSDs this drive is right at the bottom of the pack. Thanks to the combination of its now aged Sandforce controller and the use of Asynchronous Flash Memory, the Chronos has a real world speed of just 224 MBps. Its AS SSD total score of 487 is also the worst I have seen to date on a 240 GB SSD. To be fair this drive is over two years old which equates to around four generations in the very fast moving SSD space. There are far better value for money alternatives available. [Sep '13 SSDrivePro]

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]
