My questions are:

 How well does the PogoPlug handle large, 1-100 Gig, files?

 How does the PogoPlug handle file access? Are files accessed in bulk (like FTP) or on a sector-by-sector basis (like a NAS)?

Background:

I'm planning to use my PogoPlug as a way to keep my home computers -- PC, Mac and Ubuntu Linux -- backed up and their files synchronized, but I am uncomfortable with relying on https and PogoPlug to keep my PogoPlug Internet-accessible files secure.

Much of the stuff on our drives I don't worry about: application, audio/video/image files and the like, but we already have other files, such as our financial, family documents, personal correspondence, and development files encrypted using TrueCrypts.

TrueCrypt is a tool that mounts virtual volumes where the data is stored in encrypted data files called Crypts; our Fiancial files, for example are stored in a 1 Gig data file crypts, and family documents (like scanned copies of insurance policy paperwork and such) in a second, 10 gig crypt. Each user on our LAN also has a 100 gig personal space (Windows users might call this their user Documents and Settings folder.)

If the PogoPlug doesn't handle gigabyte-plus files competently or does bulk file transfers instead of sector-by-sector access I will have to re-think how our files are stored or re-consider my PogoPlug plans.
