I'm currently using an external 320GB drive enclosed in an aluminum Firewire 800 case to store my media files. It is a well made enclosure but there's something about the drive inside or the case itself that, when it goes to sleep, it does not wake back up consistently. I checked my Energy Saver settings and I have the "put the drives to sleep" unchecked. I have no problem with the drive itself deciding to spin down when not in use, but I expect it to perk right back up if I click on it. This does not always work in my case and I am sometimes forced to cut the power to the drive or the Mini will get hung-up on restart. So this little inconvenience has pushed me to look into NAS possibilities sooner than I had already planned. LaCie introduced a new drive that seems like an excellent choice: http://www.lacie.com/us/products/product.htm?pid=11247 I like the Mac friendliness, UPnP, and iTunes support. The 500GB model can be found for a good price online and I can always upgrade the drive itself later on. Since a NAS storage device implies that a network connection will be utilized, I trust the "Wake on LAN" feature will be enough to avoid the inaccessibility problem that I am currently facing. As odd as it sounds, when I try to access a share on another Mac I have on the network using a "recent server" link, the Mac does NOT wake up. I have to use other means to wake the machine up first, then it will respond to my shared volume request. This is counter-intuitive to how a friendly Mac environment should work but my work-around isn't a pain for now. On the other hand, if the LaCie doesn't respond to a request after it has went to sleep, that will be a big problem! Does anyone have any experience in this area? Thanks.
