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 '14SSDrivePro]
The 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer.
