And I have to disagree with Anthony on this one: spinning disks are going to be in use for a while as external backups: sure, they're slow, but this is a BACKUP. Cost per terabyte is immensely lower and speed isn't usually the priority, and you can put multiple copies of backups (or diffs, or whatever suits you) on one large external.
Certainly you're going to use spinning rust for multi-terabyte backup sets, but the point I was getting at is that if that's your archival set whose files are set in stone once written then you may only need to do backups of that monthly or less often, while a small active fileset (including any recent archival additions) may be in the tens or hundreds of gigabytes range so that your dailies are small and manageable and have a good chance fitting onto flash. -- Anthony de Boer
