I looked at the Synology NAS boxes real hard and ended at the top of my list. At $130 though, I finally decided to check out and think I am going to move to RAID1 devices. Bought
this one from OWC. Also bought one of
these.
Both are connected via eSATA to my Win7 box which has been converted from an HTPC to a ripper/converter iTunes/DLNA server. I did have to buy a So, I've got a backup of my media sitting there in the RAID1, plus easy backup to a 3rd drive for off site storage.
And my new MBA, with a 256GB drive and 220GB free space has an iTunes library that's 1.2TB in size.
About the only negative I have thus far with the Maximus is that once it goes to sleep, it takes almost a minute to wake up upon access.
