I have a SONOS system and in terms of a NAS I am very happy with the WQestern Digital Shared Space drive whose URL is http://www.westerndigital.com/en/products/products.asp?driveid=501

I like this drive for a number of reasons such as no third party software to connect with it, does not conflict with my office's VPN, etc...

I will also echo the above comments that although I do have the drive configured as RAID 5 I still do weekly backups of the entire drive using an external USB drive because in the event of fire, flood, surge, etc. all could be loss...the only thing the RAID 5 protects against is the failure of a drive...

Hope this helps.
