Amazon offers its Prime members the HP 128GB X702 USB 3.0 Flash Drive, model no. P-FD128HP702-GE, for $34.99 with free shipping. (Non-Prime members can spend $35 or more to qualify for free shipping; otherwise, shipping adds $8.) That's $1 under last month's mention and the lowest total price we've seen for this drive without a rebate. (It's also a current low by $25, outside of the mention below.) It features read speeds up to 190MB/s and write speeds up to 130MB/s.
A close price: Newegg offers it for $34.99 plus 99 cents for shipping.
