Pros: Worked fast, when it worked.

Cons: Died at 4 months, won't mount, can't be reformatted.

Overall Review: It didn't get much use. I used it once in a while to transfer new files from my desktop to my laptop. It was working fine, I unmounted it from my desktop, plugged it into my laptop, it was unreadable, unrecognized. Plugged it back into my desktop, it was unreadable. I opened all my disk related utilities to try and save the contents, but it was not readable. The computer asked if I wanted to format it, so I tried that, but format failed, again and again. It is totally unusable. Not worth the time or the money to deal with Toshiba with warranty, even though I paid more a few months ago than it sells for right now. Look somewhere else for a flash drive. They should last longer than a few months.
