I would like to build a portable NAS (with one hard drive of I think 4TB). I need a full Linux and I don't want to fiddle around too much to make it work (no patching and compiling my own kernels and stuff like that).
For this I need a
- small (say like two 2.5" drives on top of each other, plus at most 50%),
- low power (not more than 3W idle, preferably less)
- SBC (single board computer)
- with SATA (one port, preferably III, II is okay too, doesn't need 12V, just for 2.5" drives)
- and Ethernet (Gigabit).
- Bonus if it has an integrated Li-ion controller (or if you know some separate Li-Ion battery controller board for 5V uninterruptible output).
- Bonus if it doesnt have a crapload of unnecessary features/connectors.
Raspberry Pi doesnt have enough performance (the limiting factors are USB 2.0 and crappy Ethernet, I think) and mATX/mITX boards are too large. What can you recommend for maximum data throughput? I would like to get at least 40MB/s actual real world throughput.
It should be as cheap as possible. That said, as long as it's significantly cheaper than buying a laptop and ripping off / not using the screen, it's okay. If there is a ready to use NAS (without hard drive/empty enclosure) like that I'm fine with that too.
