Hm,
If the SATA connector is like the PI plus boards, it is a USB to SATA connector. Hence it would have a max. data through put of 480Mbit/s = 80Mbyte/s, not counting the loss to protocol transfer. To find out if there is something mentioned in the PI Plus schematics, I tried to download them, but the google drive link is broken (again...).
Interesting would be the maximal data rate for the GPIO and also it would be good to know what interface data rates the MSATA or M2 connector has.
But IMHO the OrangePI and all the other development boards are not usable as NAS (e.g. the BananaPI R1). They all lack of the necessary speed. None of the allwinner boards reach even the 1000Mb/s network speed.
A NAS required different hardware after all. I did build out of my old AMD 870 mainboard a RAID 5 NAS. There I have full SATA3 speed and GBit LAN. My old PhenomII is running on 2 cores only @ 800MHz and the whole system uses about 10W in IDLE and about 35W on full load.
The Orange PI's or others will never reach the full potential of a real NAS. But they have so many other uses e.g. smart home, smart tv box, CCTV, CNC and so many others. |
