My setup consists of the following: New SR MPB for me Dell desktop running WinXP that I was hoping to retire soon Asus laptop running WinXP - my wifes computer Networked HP AIO printer Verizo FIOS supplied wireless router (Actiontec) Vonage device I wanted a large external drive that can be shared by all on the network but also have firewire 800 and maybe eSata available for fast direct connections for backups and large transfers. To be able to use the drive on any computer, avoid file size limits, maintain high transfer speeds, and have time machine work when available it seems that the only practical option is to have an HFS+ formated drive and install Macdrive on the WinXP machines. However this significantly reduces NAS options. The Lacie NAS drives can do HFS+ but they have no firewire and I've heard the transfer speeds are not great even with direct connections. I can use an airport extreme base station + external drive which would probably work well (I know it will be a little slow on the network) but it is very pricey. The third option is to keep my WinXP desktop networked and use it to share the external drive. The last option is what I'm currently planning on doing with a Samsung 500gb SATA HD + OWC Mercury elite usb 2/fw 800/esata enclosure. Anyone have any other recommendations?
