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]
