Is it video storage as in serving videos on the web from that disk or as in storing them and sometimes copying / watching from the disk?
In the latter case, seek time shouldn't be a problem. I've got an usb 1tb drive sitting here and it's working just fine for the usual usage. As far as prices go, the upgrade isn't really that big, so instead of buying two 500gb, I'd just take two 1tb and have a backup.
