    My previous Gorilla Drive 256GB flash drive took a dump so I decided to switch to this impressive one.

    Pros:
    -Durable case
    -Fast speeds
    -Screw to open and close instead of a pop-off/slide cover

    Cons:
    -It may be easy to lose the case part that screws off, I would have personally made the rubber rings more of an octagon shape to prevent rolling

    These thumb drives screw into a metal container - which is as close to a bulletproof housing as you are going to get. This makes them suitable for travel, even wilderness travel. They are not the cheapest or highest capacity drives out there, but I have several and have found them to be reliable. No need to get these if all you are doing is transferring files from one computer to another, but if you want to travel with them, or backup stuff for a long period of time, I recommend these as a good option.

    If you're like me and kind of rough on things, this is a must buy. It is very well built. I was going to put it on my keyring but I didn't want to scratch it. I have no doubt that it could of took the abuse though. I use it almost daily to work on a project at the house and on the go on my laptop.

    I wish it didn't look as good so I could put it on my keyring but I opened it up and decided I didn't want to get it scratched. That would be the only "bad" thing, if you can call it that, to say about it. That it looks too good.

    These are probably one of the best usb storage devices on the market. The only issue I have is that they are costly little buggers. They are clearly double the cost or more of similar products in the same category. I've ordered both the 128 Gb and the 256 Gb devices. Both are solid and reliable. I very much like the protection their covers afford when transporting from place to place. Full aluminum outer casings with rubber seals and fast transfer speeds while using. Now, if only Corsair could lower the cost a little - really?!
