Tingin ko ang mas limitation niyo dito ay kung gaano kabilis yung usb drive niyo at kung gaano kabilis ang wifi niyo. Kayang kaya ni pi na mag host ng shared files.
I actually tested it, unfortunately, stuck lang sa 7MB/s yung transfer speed ng rpi/rpi2 (any revision), due to
1. Shared bandwidth ang USB devices, that includes the ethernet which is also connected on USB bus
- unlike banana pi, banana pi has its own interface for ethernet chip and last but not the least, gigabit capable sya, as my test with banana pi, it can achive 23MB/s easily if you access your storage with builtin SATA port or around 18-20MB/s in USB port.
2. Dont have its own USB controller separated, nasa SoC mismo yung USB controller so, yeah...
- banana pi got this USB controller separated on its SoC
From my tests, banana pi wins when it comes to a standalone low power server thing. parang pogoplug lang din ang specs nya.
Edit: test were done formatted at ext4 using arch linux. So your milage may differ depending on your setup, specially NTFS.
