How to disable software raid on SME 7.0 A26?
It is a misconception is that software raid is inferior. You'll find many opinions if you search around the net, but when people take the time to test and document, they usually conclude that on today's fast CPU's, Linux software raid is just as good or better.
This is a fairly recent benchmark someone made comparing a 3ware raid card (not a cheap card) to linux software raid:
http://spamaps.org/raidtests.php"I think in this test we've shown that the 3ware's hardware RAID5 is totally inferior to Linux 2.6.x's Software RAID5. The only advantage to using it is that when you're dual booting, it will work the same in Windows/Linux. For a server, its not even an option, as you see the dips in the concurrent numbers. It might be more fair if the 3ware could use larger chunk-sizes than 64KB."
And about cheap SATA raid cards:
http://linuxmafia.com/faq/Hardware/sata.html#fakeraid"Most ATA RAID host adapters (except 3Ware Escalade, Adaptec 24x0, Areca, HP/Compaq, IBM ServeRAID, Intel SRC*/ICP Vortex, LSI Logic MegaRAID 150-4/150-6, and Tekram) turn out, upon examination, to not be real hardware RAID, but rather software/BIOS-dependent fakeraid. (I.e., missing hardware functionality is traditionally emulated inside idiosyncratic, undocumented, and proprietary software drivers, to hit low price points). Fakeraid is difficult to support in Linux — absent either reverse-engineering, special proprietary drivers, or (rare) manufacturer cooperation. (HighPoint, LSI Logic, Nvidia, Promise, and VIA provide proprietary drivers to support their respective fakeraids. I personally would steer clear.)"
