Not you again Mktdude
- only kidding.
I know where you are coming from as I have been there myself (as you already know
Lets take this bit by bit.
Given your Metastock analysis programs require the RAID 0 setup (I am about to order my 2nd 7k60 and go RAID 0 over Christmas btw) to speed up report writing I would run your main system on RAID 0.
To use RAID 0, WinXP requires RAID drivers at install time (the 8890 comes with two extra floppies with the RAID or ATA non-RAID drivers on them which you insert into the system during install). During system config you would set the DIP switches to RAID, install WinXP with the RAID drivers from floppy and there you have your normal system.
Now the limitations. The third disk will only run in ATA mode (it is not RAIDable). As a consequence of this you cannot use Ghost or bitwise backup systems to copy your WinXP+RAID system onto the third drive and expect it to work (there is a way but it involves physically moving disks). In order to boot Windows from the 3rd disk you must have Windows setup with an ATA driver.
Not all is lost however. Instant recovery. This is how I would suggest you setup your system.
1. 2 x 7k60 disks in RAID 0 config.
2. Install WinXP with RAID driver
3. 1 x 7k60 in disk bay 3
4. Install WinXP with ATA driver
5. Configure both copies of your OS to how you like them.
6. Load your applications software onto both copies of your OS.
7. Load your data onto the WinXP+RAID disks.
Now your backup is not a backup but a disk to disk copy of just your data. At some point you are going to have more data on your WinXP+RAID disks than will fit on your 3rd disk. At that point buy a dual FW/USB mini external PS/2 powered, 2.5" disk enclosure
to handle any extra data that will not fit on the 3rd disk. These external enclosures are small enough to slot into your carry bag and do not need an external power supply.
In the 4.29%
chance that one member of your RAID array fails, all you do is to go to the BIOS and change the boot sequence
and then boot from the 3rd disk. If you need the external disk just plug in your PS/2 power tap and FW or USB cable and you are on the air.
