I have run into one source of slow-down on occasion. The external devices each will need their own power supply module so they don't rely on the host port for power. One thing to watch out for, though: for devices like CD or DVD burners, the USB2 system can NOT supply enough power to operate them just from a USB2 port. In fact, very often when you do that you do NOT actually use all or even several of them at the same time, so the bandwidth limitation really applies only to the devices actually in use simultaneously. Hubs are certainly a good way to connect many external devices. I'm mostly looking for thoughts or any gotchas I might not be thinking of. USB external drives are marginally more expensive but hubs are stupid common, power is an easier to solve issue and they would be easier to mount or I could just not mount them anywhere and stack them up.
With limited SATA ports I'd have to use port multipliers (seem finicky and not commonly used) and get creative with mounting and external power. Solve it parallel instead of trying to speed up serial.Ī quick ebay even shows if you want used you can buy them for $8 shipped all day long. Why not just brute force the problem and make a stack of them. I regularly see external DVD burners on sale for like $13. Then I realized I was really over-complicating things. I'd thought about trying to build a robot out of something (unrealistic) or buying an old loader off ebay (I seem to recall them being expensive and they probably require a lot of babying).
I was ripping an audio book yesterday and wishing I had a loader robot since it requires a lot of manual intervention. Of course, those are theoretical bandwidths and the USB 2.0 one (60MB/s) I've never seen in the real world. It seems like at 52x I was at ~7.5 drives per USB 2.0 port.
