01/10/05: Serial ATA (SATA) on Linux

Jeff over at nethub.org has found a good article about Linux's support of various SATA chipsets. SATA RAID is near the top of my list of things to try, and for anyone else considering it, this is a must read. Jeff writes:

...not all Serial ATA controllers are created equal. Most Serial ATA controllers claim to have RAID capabilities built in, but keep in mind that true hardware RAID capabilities are only available from a very few cards. I've seen many headaches related to the "fake" or "software-based" RAID that many of these cards cause.

After the many good things I have heard about Linux software RAID capabilities, I may just go that route rather than buying a much more expensive hardware RAID solution. Afterall, I'm cheap and stubborn. Still, how disappointing it would be to buy incompatible hardware, especially with a 25% restocking charge. Keep that in mind before you run out and buy a bunch of SATA drives.

When you look at a motherboard with Serial ATA on-board or if you look at purchasing a PCI Serial ATA controller, I would highly recommend doing lots of research. I've run into a few that simply refused to work in Linux. Others work, but at such painfully slow throughput speeds that I felt like breaking out an old 850 MB PATA hard drive from back in the day and doing a speed test comparison. LOL

Google is your friend.
