As one of its daily deals, Woot offers the Centon 64GB DataStick Rush USB 3.0 Flash Drive in Black, model no. S1-U3P6-64G, for $19.99 plus $5 for shipping. That's the lowest total price we could find by $8 and the best non-rebate price we've seen for a Centon 64GB USB 3.0 flash drive. (For further comparison, we saw a similar model bundled with security software for $10 less after rebate hassles in December.) The drive features a capless sliding cover and up to 25MB/s write speed.
