Max,

I use a 440 for development - does a fine job. If you really are limited to 3 18GB disks, however, you don't have enough drives or disk space to stripe and mirror. Slicing the disks up the way you are describing is a waste of time. You will get zero benefit and quite probably make it more difficult to manage the space for your database. When you install Solaris, create the least number and largest size partitions that you can.

BTW - SCSI drives are cheap on eBay.

Good Luck,
