Summary: Having just received this I can't comment on the durability, but the other Kingston products I have purchased have been first rate. The product appears well made, and installed easily in the usb port, and Windows 7 automatically loaded the drivers and recognized the new drive. While I had ample space left on my laptop hard drive, I bought this specifically for what is called a swap file to allow faster computer memory swaps.
Summary: Only had this for a few days, but have always had good service from Kingston products. Was purchased specifically to provide a solid state drive for "ReadyBoost" on my laptop. Windows will set up a dedicated section of the flash drive about twice the system memory. This appears to reduce the amount of hd access, and seems to speed up some operations.
Excerpt: I was looking for a flash drive to take with me on a photo trip to Iceland. I intend to use it to back up my photographs. The Kingston is perfect and I should have no problem with enought storage.
