Don't make the mistake of thinking you are getting an affordable NAS via your existing USB storage drives with this gadget, even though it says it is a "Storage Server". I got it to attach a Freecomm via its USB port to my LAN's router as it said it was a storage server. Well the issue many will have is that if, like a lot of folks, you want to have access to your USB storage from multiple machines on your LAN simultaneously then you will be in for a shock because this gadget appears to only present itself as an IP address without any SMB/NFS/etc sharing included. You have to install the TP-LINK included software on each and EVERY machine on your network and then the software allows you to, essentially, mount that USB storage from a SINGLE machine at any ONE time and you have to make "a request" and "accept that request" for the ability to grab the USB storage from that original machine for use on any other machine on the LAN each time. This means that using any automatic backups of LAN machines to your USB storage via this device are not feasible. The only way to get around this would be to dedicate one of your LAN machines to mount and share the device which would mean having that machine running all the time. Duh!
