For higher end systems with lots of I/O and very large storage needs it may be necessary to go with a high quality hardware RAID card with a large battery backed cache. For smaller systems Linux does software RAID very well, especially in these days of fast, inexpensive processors and inexpensive memory (compared to several years ago). One thing to consider is what happens a few years down the line and your hardware RAID card dies. Can you replace it? What happens to your data? At least with software RAID you can replace the controller and everything can be brought back up. I've been using soft RAID on my own and several client servers for a few years with no real problems. Hope this helps. -- Kourosh <linux-raid@mindwaresystems.com> - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
