It's been my experience that high quality disks, such as the Western Digital Caviar series, will last 5 years and should be replaced at that time!!! I find most other brands to be suboptimal, e.g., expect a head crash and catastrophic loss of all data. The Caviar Black disks spin at 7200 RPM and carry a 5 year warranty! I've had poor luck with Seagate. YMMV. I realize that a RAID array is redundant but is it worth being cheap to hopefully replace every failed disk before another one also fails? Understand that the MTBF is less than that for one disk increased by being able to continue until two disks fail. This is because, assuming all disks of the same type and time in service are more likely to fail around the same time, same as incandescent light bulbs. I suggest, if you use refurbished disks, pick a RAID mode, such as RAID6, with double redundancy due to two different parities that can withstand two disk failures in the array. Wikipedia's "RAID" entry is excellent. If the cost isn't out of your pocket buy new WD Black!

I want to add a few more drives to the NAS. _______________________________________________ Ale mailing list [email protected] https://mail.ale.org/mailman/listinfo/ale See JOBS, ANNOUNCE and SCHOOLS lists at http://mail.ale.org/mailman/listinfo
