I just built a new system, and as is my wont, I intended to equip it with a pair of mobile racks so that I could have switchable drives - one being the clone of the other. That is 100% redundancy. I have been doing that for about 4 years now, and it works well.
But, I decided to try a more sophisticated system, the Trios II multi-drive selector by Romtec. It consists of a contactless controller card that sits in a PCI slot (no electrical contact there.) Then there is a bridge cable with a feeder that goes in between the P/S ATX connector and the mobo, with a long lead that plugs into the Trios card. There are 4 IDE ports on the card. One goes to the primary IDE controller on the mobo. Then there are designated IDE ribbons going to up to 3 IDE drives along with numbered power cables. Then a small desktop controller allows the user to select 1, 2, or 3, or 1+2, or 1+3 combinations.
I installed this system easily in less than 30 minutes, and have found it to work very well - as advertised. Today I used it in the 1+3 mode to clone drive 1 to drive 3 using DriveCopy boot floppies.
Trios
I can honestly recommend Trios II for anyone who wants to boot from up to three different drives.
