A Buffalo sales rep directed me to pogo plug in the first place. They use Pogoplug functionality, but their drives require Unix formatting even for USB blugins. So Pogo was an easy choice.

I can't see any advantage in buying a Buffalo to having a USB plugged into a Pogo. Except that the Buffalo is also, I believe, a true NAS, directly accessible by LAN, where a Pogo setup isn't. Although the internet access isn't that slow with my U-verse internet service, it would have been annoying with my old basic DSL.

The Buffalo has both internal drive connectons and external USB ports--and the drives plugged into the USB must also be linux format. Which means you can't temporarily disconnect a drive and plug it into a mac or winbox (because the Buffalo has a linux engine which requires a linux file system, which in turn is unintelligible to mac or win OS). This is also true of the Seagate version. Iomega I think might be agnostic on this.

If this might be an issue, call and ask first. I did, and that directed me to a Pogoplug as a more economical option for me...presently using old notebook drives as they are fast enough and virtually free.

If, though, you want to drop your Biz for a Buffalo, I'd be interested in buying your used Biz...
