Weme via Amazon offers its Weme USB 3.0 to Serial ATA Converter Adapter, model no. BC78839, for $21.99. Coupon code "Y4IHNYNL" cuts that to $10.99. Plus, Prime members bag free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, it costs an extra $8.28.) That's tied with our November mention, $11 off, and the lowest total price we could find. It supports 2.5" and 3.5" drives up to 8TB.
