Ahh, biased figures. I am rather tempted to say that the Kingston SSDNow V300 120GFB is slow, because it is rated at 'only' 450MB/s read, 450MB/s write, and 85,000 IOPS by the manufacturer -- but what gives?

The Kingston SSDNow V300 is yet another value-oriented SSD in Kingston's wildly successful line of mainstream solid state drives. With the pressures of TLC SSDs squeezing the value market we take a look and see if a standard MLC SSD with 19nm Toshiba Toggle NAND and an SF-2281 processor can keep up...

As is typical for the SandForce (LSI) drives, the Kingston V300 120GB drive has ~7% overprovisioning that offers the user 111GB of usable space. If you were to purchase the 240Gb version, you'd find yourself with 223GB.
