It really depends on what you mean by low cost? The ony ide raid controller that does 8 PATA drives well under linux is the 3ware controller. For SATA drives you have the 3ware, and adaptec controller. In theroy the highpoint 8 port sata card would be a good canidate for software raid, but highpoint has yet to cough up an open source drive yet. It you want to go the software raid route and have 2 spare pci solts. You can go with either the high point rocket raid 454 (PATA), or the promise SATA150 TX4. I really don't recommend any of promise's cards that use use the i2o driver, or any sort of binary only driver. PS- Why not at least run software raid 5? It takes far less cpu than you'd think, and can save your ass.
