I have googled to no avail, so I thought I would ask here.

Quick background on what I am trying to do :

I have 300+ dvd's and 500+ cd's (yes i know, i have been collecting for years and am a sucker for discount bins!) in my collection I am about to start ripping to put on a plex server.

So here is the actual question:

I can buy a lot of 20 usb external dvd roms on ebay for a little over $100. Each one has its own wall plug for power. So if I buy a powered usb hub, how many could I plug in at one time and the pc recognize? The software will see any numbered drive and let me check to copy it. I want to load up as many as possible and let run thru the night.

The pc itself has more than enough horsepower to do it (dual xenon workstation, 16gb ram, Quadro card, win 10 pro, etc) and it will be storing the ripped dvd's to the plex server.

I was thinking about a hub like this and 12 dvd roms at a time.

usb you can have a max of 127 devices connected at once!


BUT since each drive requires a drive letter and you only have letters d: - Z:  available, once their all used up our done.


buy the little portable players for like $25ea without power, your usb adapter you provided in the link is powered so it will supply the power needed to run them.
