If you’ve been dissapointed with the performance of commercially available hard drive docks (and more than a few people have) this spartan DIY solution removes the bottlenecks most commercial docks are crippled by.
Marc Bevand shares a DIY solution for a situation he’d had enough of, hard drive docking stations that were unreliable and limited in transfer speed by cable limitations and crappy chip design. He designed a tiny coin sized SATA power module that runs off a 12v wall adapter and an SATA power cable. The voltage is stepped down, via his lilliputian power module to 5v. The entire build cost him $9 and was a huge step forward in removing variables from his drive docking and diagnosis procedure.
