How fast can a Raspberry Pi 2 file server be?

I thought I’d measure the performance of a Raspberry Pi 2 SMB server… with the on-board 10/100 Ethernet, and a USB Gigabite adapter.

There have been so many questions on the forums about using the Raspberry Pi 2 as a server – and some unrealistic hopes of gigabit performance – that I ran more tests than I originally intended to pin down the performance limits.

I welcome your feedback on my forums – or the Raspberry Pi Forums!

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.

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 🙂
