The 128GB Transcend SSD370 proved to be a bit of a disappointment both in absolute terms and in comparison to its larger capacity 256GB sibling. The 128GB SSD370 is let down by its abysmal peak sequential write speed of just 158 MBps which is the lowest speed we have seen to date on a ~128GB SATA 3.0 SSD. Comparing the 256GB and 128GB versions shows that 256GB capacity drive has nearly double the write speed which is typical for larger flash based drives. In terms of value for money the 128GB SSD370 fares a little better but there are far faster and moderately cheaper alternatives available in the extremely competitive SSD market. [Oct '14 SSDrivePro]

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]
