I want to use multiple OS (not at the same time) and I don't want to install all OS in one HDD. So I want to use an external USB 2.0 box (my Dell T3500 only supports USB 2.0) and several HDDs. Each OS for one HDD. When I want to switch OS, I can just shutdown the current OS, replace the HDD, then boot it.
My concern is about performance. Will it have significantly performance downgrade? Thanks.
P.S.: I also tried a 3.5" SATA HDD box but the CD/DVD bracket is 2~3mm smaller than the 3.5" SATA HDD box so I can't install the HDD Box in it. :(
