Raspberry Pi 2 runs nicely on a SATA hard drive using a USB/SATA enclosure

Saturday, February 28th, 2015

After testing USB SATA adapter performance on the Raspberry Pi 2 Model B, I decided it would be nice to have a lot more disk space for Raspberry Pi 2 development work for RoboPi and my other projects. Raspberry Pi 2 USB hard drive and adapter tests

I used gdisk to re-partition the 3TB 7200rpm Toshiba SATA drive, making a 200GB ‘usbroot’ partition, and making a ‘usbdrive’ partition for the rest of the drive for files.

It will be interesting to see how it performs as a development box – will the extremely fast seek times of an SD card be more important than the (roughly) twice as fast disk read speed?

The Raspberry Pi 2 is quite capable of being used as a development system, so I’ve decided to make a dedicated RPi2 development box I can ssh and rdp into from anywhere in my network.

So far I can report that the system feels snappier, especially when loading large applications. I will probably do some more tests later.

The output from ‘df’ is also pleasing :)

(Please let me know if y’all would like an article/howto on how to set up such a box)

Curious about the new Raspberry Pi 2 Model B and how it compares to the ODROID C1, Banana Pro, MIPS CI20 and Model B+? I was!

Here is my largest and most comprehensive single board computer review to date. I added more benchmarks – so now there are some usage benchmarks (boot and launch times), development benchmark (compiling Emacs), and a lot of synthetic benchmarks, power utilization test and mure.
