Hi all, I am new to the world of NAS devices. I have 5 X 3.5" Sata HardDisks which I would like to share the data around my home network. I have 2 notebooks, 1 netbook, 1 iPad, 1 desktop and a PS3; I would ideally like to share my files with all devices, and it will be a bonus if I can create different user account for access. I would like to spend around £150-£350 ($240-$550USD) on the NAS. Any advice would be appreciated.
