Basics of RAID

Posted by Zonk on from the brush-up-on-the-essentials dept.

Doggie Fizzle writes "RAID has been common in business environments for ages, and is now becoming more viable and popular for personal computers. This article focuses on the the basics of RAID, and spells things out for beginners or tech veterans. From the article: 'The benefits of RAID over a single drive system far outweigh the extra consideration required during installation. Losing data once due to hard drive failure may be all that is required to convince anyone that RAID is right for them, but why wait until that happens.'"

    Here is a link that explains the basics of computer hardware; I think that it's a good companion piece to the RAID article: http://www.angelfire.com/rings/judy_patch/

    IDE HDD Talking to IDE Controller:
    HDD: I'm gonna need more time for that write
    Contr: Yeah OK, go ahead good buddy
    Contr: What's up?

    SCSI HDD Talking to SCSI Controller:
    HDD: I'm gonna need more time for that write because I found a bad block
    Contr: Yeah OK, go ahead and remap that bad boy
    Contr: What's Up?
    HDD: Need more time to map that bad block
    Contr: Yeah OK, go ahead
    HDD: All done, grabbing the next command in the queue

    Yes!!!! I now can point my PHB to this article, and then to the article on how to turn IPods into a raid, and that should be enough to convince him to buy a few dozen. Now I will just need to explain to him why having a spare Ipod stored at my house will be a wise decision, you know, just in case the vendor closes it doors tomorrow or does something 'crazy' like switch architectures next year.

    You think that's bad. See my article on why SATA is better than IDE. It's only more relevent now than when it was written, 12 years ago.

    Yes, it mentions that in the article: RAID 0 is one of the configurations that does not provide redundancy, making it arguably not a true RAID array.

    Well, if it's a RAID array, I think it is redundant.
