Average Bench: 53.8% (850th of 1058)

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]

Average average bench

The Kingston SSDNow V300 120GB averaged 46.1% 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 39.1%. 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.

Perfect SSD for upgrading 5 years laptop. Super cheap.

This drive is installed into a 2007 Mac Mini used as a media centre. Although it's not a fast SSD drive, it's perfect for this old Mac where the real bottle neck is the drive bus speed. Super fast compare to a standard HD, and has extended the life of this machine yet another couple of years. Thanks Kingston for your super cheap, yet super under performing drive. Works for me.

Measurable fast boot up speed increase but that's to be expected with an SSD. Will do more research before my next SSD purchase as the size is a massive limitation of the value of this product.
