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]
