The OCZ Agility 3.0 has a relatively weak performance profile to say the least, it is actually one of the worst drives we have seen to date. With a real world score of 275.1 MB/s and an AS-SSD total score of 593 the Agility is the worst performing drive in our group test. To be fair, this is one of the oldest models in our group test and has already been discontinued by OCZ. If this drive halved in price to around £70 we would begin to get interested but at its current market price of £140 it represents very poor value for money. [Feb '12 SSDrivePro]

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]
