This is low cost NAS (Network Attached Storage) device with some neat features:
1. 160GB hard drive
2. USB Print server (probably won't work with All-In-One machines).
3. USB ports for additional external HDDs (FAT32). Not sure if it works with USB hub.
The price is very good for networkable disk. OK, the performance isn't top notch, as it shown by Tom's Hardware test
but for the price it is hard to complain.
