Thanks for the performance report. The V+100 is based on a Toshiba T6UG1XBG controller, and it doesn't have any durable cache from either a battery or capacitor. As such, putting a database on that drive is very risky. You can expect the database to be corrupted during an unusual power outage event. See http://wiki.postgresql.org/wiki/Reliable_Writes for more information.
At this point most people considering one of Kingston's drives for a database would be better off getting an Intel 320 series drive, which is around the same price but doesn't have this issue.
