Yes. And I believe I first said this here on the BLU list sometime around, oh, 2003 or so. Motherboards almost always have 6 or more SATA connectors, brand-new disk drives have plummeted to about $60. CPU and RAM overhead is negligible (under 3%) when you set up software RAID1 or RAID10. And you get 2x the read performance if you use RAID1/RAID10. Q.E.D., unless you're concerned about 60 bucks (or the $4 annual electric bill per drive), then there is no reason not to install hard drives as pairs. Ever. Even if you can't spare the $60--you probably have old disk drives lying around that you can use. For free. Never run Linux without RAID. Ever! -rich _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
