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]

MORE DETAILS

The SX900 and SX910 are both Sandforce 2881 based SSDs from Adata. The only difference between them is their warranty period: 5 years for the SX910 vs 3 years for the SX900. Both drives utilize Intel-Micron 25Nm MLC so the differences must be at a "sub-atomic" level, or at least beyond the scope of the specs. Once again as with all Sandforce 2881 based drives performance is skewed in favour of reads over writes. With a peak sequential read of 510 MB/s and corresponding sequential write of 309 MB/s the SX series does not break any records but, like all SSDs, they do offer speeds way in excess of mechanical hard drives. Overall performance lags the SSD group leaders by around 40% and there are far faster, cheaper and newer (non-Sandforce) alternatives such as the Samsung 840 Evo or the Sandisk Ultra Plus available. [Jan '14 SSDrivePro]
