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]

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]
