Average Bench: 46.9% (653rd of 848)

The 120GB Kingston V300 has a performance profile that closely matches its 240GB sibling. Both drives utilize a Sandforce LSI controller and therefore demonstrate relative weakness in their write speeds. With burst sequential read/write speeds of 497/166 MBps and 4k burst read/write speeds of 30/97 MBps the 120GB V300 is amongst the slower SSDs I have seen. A concern I have with this drive is the relatively slow real world speeds our users have experienced. Most drives have average throughput rates that are around 75% of peak. Both this and the 240GB V300s, based on 130 samples, are averaging sequential read rates of around 240 MBps which is less than 50% of peak. It's not all bad news though because the V300's are priced extremely aggressively and as a result still offer decent value for money. [Feb '14 SSDrivePro]


Below average average bench

The Kingston SSDNow V300 120GB averaged 53.1% lower than the peak scores attained by the group leaders. This isn't a great result which indicates that there are much faster alternatives on the comparison list.

Above average consistency

The range of scores (95th - 5th percentile) for the Kingston SSDNow V300 120GB is 36.7%. This is a relatively wide range which indicates that the Kingston SSDNow V300 120GB performs inconsistently under varying real world conditions.

The devices s/n 501 to 504 were performing way better than what Kingston is offering now with the s/n 506 and up. This marketing idea of starting with a good product, get good press and then keep only the case is bad. Do not buy Kingston.—Sep '14

It gave new live to my old laptop. For a very convenient price. Maybe is not the best SSD, but it is cheap and fits well to my needs.
