I'm looking to replace my aging DIR-655 and the new DIR-857 looks appealing. This C-Net review has this to say about the USB port on the device:
SharePort is a useful feature of D-Link USB-equipped routers that enables the router to support any USB device as though it were connected to a network computer directly. Over time this technology has evolved from allowing only one computer to access the connected USB device at a time, to multiple access, and now, the ability to share data via the internet.
Can I connect a drive array to this port such that multiple Macs in my network can do their remote Time Machine backups to that attached storage space?
Will it handle a HFS+ formatted file system?
And as a bonus:
- Will it handle a Drobo?
I know none of the above is possible with the DIR-655 I have now.
Some clarifying points:
I realize I could do this with a TimeCapsule but I have all the disk on hand already with the Drobo and I happen to really like the features of the D-Link firmware (see my comments in Kyle's answer below for details)
Daniel Beck has found out that the SharePort software does work on Mac, but is it Time Machine friendly? There are non-Apple, remote storage devices that do support Time Machine (see this ReadyNAS FAQ for example) so is this similarly blessed and compatible?
