Can anyone please recommend a NAS that has both Read & WRITE support for external hard drives attached via USB (or eSata)? I have several 1TB WD My Books that I would like to be able to add to the NAS for additional storage. It seems virtually every NAS I have come across is read only. I realize I could re-format as FAT32, but since many of my files are larger than 4GB, this really is not an option for me. The inability to write to an external NTFS formatted USB drive is a really a dealbreaker for me. Thanks much in advance for the thoughts.
