This is yet another Sandforce 2881 based SSD from Kingston, this time coupled with newer 19nm Nand flash. In terms of performance the V300 is nothing we haven't seen before with other Sandforce based SSDs. A side-by-side comparison with the HyperX shows that the two drives have a near identical performance profile which is more than a little disappointing given that the V300 is 16 months newer. With a sequential write speed of just 280 MB/s the V300 lags the group leaders by 62%, an expected result for a Sandforce based drive. To conclude, Kingston aren't offering anything new with the V300, consequently there are far faster (and cheaper) drives available elsewhere including the excellent Samsung Evo which is the current group leader. [Jan '14 SSDrivePro]


We had high expectations for the Crucial M500. Crucial have a long history of producing outstanding Solid State drives. Both the RealSSD 300 and the M4, three and two years old, were almost legendary in terms of reliability and performance. The M500 falls far short of our expectations. The drive is relatively cheap and as such we were expecting to compromise on performance but the M500 just falls too far short. With a Real World Performance of 377.5 MBps which is in the bottom 40% and an AS-SSD score of 901 points (50th percentile) the M500 demonstrates relatively weak real world and average server performance. The M500 is competing with the Sandisk Ultra which manages to squeeze out significantly more performance despite sitting in the same price bracket. [Jun '13 SSDrivePro]
