Ocean Technology via Amazon offers its Unitek Aluminum USB 3.0 to Serial ATA Dual-Bay Cloning Hard Drive Docking Station for $39.99. Coupon code "7MPR2P9B" drops it to $31.99. With free shipping, that's $12 under the lowest price we could find for a similar dock elsewhere, although we saw a similar Unitek model (made of plastic) for $8 less last month. It supports 2.5" and 3.5" hard drives and SSDs up to 8TB and features an aluminum body, data transfer rates up to 6Gb/s, offline cloning, LED indicators, and a 30-minute auto sleep function.
