5 Just what I neededdaveplay1 | 08/03/2012 | See all daveplay1's reviews (3)Read great reviews on Amazon about this ethernet switch however it was cheaper here on Play. I have a NAS drive that was connected through a router to the PC but that had just a 100Mbps through put. This meant that with the overheads I could only transfer large files from PC to NAS drive at around 8MBps. For a 2Gb file that is slow! Plugged this in and straight away I am transfering files at 30MBps which is about as fast as the NAS can go and over 3 times quicker..excellent.
