Yes, but in order to cache you have to read the data from somewhere first. And eventually write it to disk. When you're moving multi-gig video files and such, you run out of cache very quickly. $269 for 1gb RAM drive is crazy price/meg when you can get 200gb IDE drive for $89. The solution is SCSI (or SATA) drives, and lots of them. On different PCI/SCSI/SATA buses, and lots of them. That gets pretty expensive... it's cheaper to wait a few minutes for the file to transfer. :) As far as doing gig-E at home, i say why not. It's cheap enough now to do it just for the coolness factor. Gig-e is not going anywhere, so it's not a bad investment. ray
