Could be network speed.

Will check it out later as NAS is cable to Wireless AP (Which is cable to router which is DHCP server), but PC and PS3 are direct to router. Really cant see that causing an issue with speed though as all are hardwired and the AP should act as a hub surely...

Depends. Are we talking 100Mbit network or gigabit LAN? 100Mb will top out at ~12MB/s.

I'm always wary of mirroring, chances are if the data on one side gets deleted/corrupted it will on the mirror too. The only benefit I see is if the disk totally craps out, and I'd prefer off-site backup to allay that fear.

I'd stripe 'em for speed and sync one-way to Crashplan

I have a Buffalo NAS which was very slow transferring files till I changed the ethernet frame size to jumbo (4,102 bytes), which helped.

It cost £60 + Hdd's Not a problem, I'll just line it up overnight and let it run, then finish over the weekend. Thanks tho.

Its only annoying while setting up and transferring approx 500gb to the NAS from different PCs. Can i turn RAID 1 off (or even remove the RAID 1 drive), copy everything at a quicker speed, then put the drive back in for it to rebuild and catch up?

That make sense?

Does it not have a USB port on it? I used to use an external USB drive and shanks' pony to transfer large amounts of stuff from a PC to my RAID NAS.

Turning off RAID will not speed it up massively IMO and it'll take a while to rebuild that array.

It's either connections or some disk problem ...
