[Andrew] was left wanting by the slow hard drive in his 2011 Mac Mini. He set out to add a 10,000 RPM drive and we think he did a great job of pulling it off. Luckily he also took the time to document the process so you can try it yourself.
As with a lot of Apple products, a big part of this hack is just getting the darn thing apart without breaking something. Once that’s done, you’re got to do a little bit of interface hacking. To save space Apple uses a non-standard SATA breakout cable so [Andrew] starts by ordering a second hard drive cable from the company. He then soldered a thin wire connecting 12V from the motherboard to the 12V pin on a SATA connector. From there it’s just a matter of altering the original hard drive sled to make room for the 500 GB WD Velociraptor drive. It fits below the original and serves as additional space instead of as a replacement.
