"Arguably" is right. I did some researche on this a while back. The counterargument is that retail HW raid controllers have slow processor, and that some are actually SW raid disguised as HW raid. If you want FAST HW raid, you have to pony up for the expensive ones. Some say kernel-based SW raid performs at par with off-the-shelf HW raid controllers on today's crop of multi-core processors. I haven't actually benchmarked it, but google around and you'll find a lot of comparisons and debate on this. --- mike t. _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
