NAS advice anyone?

[Skywatch]

Hi,

I have decided to remove the USB HDD from the pi and instead get a NAS solution that I hope will remove some 'niggles' with the current set up.

I have tentatively decided on a Zyxel NSA325 with a pair of Western Digital 3TB drives in raid 1.

Can anyone tell me if they have experience of that NAS and/or if this would be a good solution. Are the better options for around the same price leve (that lot should be about £270 all in).

Thanks
