    Well, I wasn't mystified by RAID - though I once looked forward to having a RAID 5 array - when I had only a single 80MB SCSI drive and started reading about computers. Actually I'd still be interested in RAID 5 if the cost for a decent controller wasn't so ridiculous.

    Anyway - good article - hopefully it stops a few more people from putting valuable data on a RAID 0 or JBOD array.

    Always wondered somewhat what RAID3 and RAID4 were, not that I ever really cared ;) Good read - I like these recent storage-esque articles, like the recent DIY home server one as well. Partly because I'm in the market, and partly because there's a distinct increasing need for stuff like that in the home for media whores like myself. Keep up the good work!

    excellent article. i consider myself a total RAID amatuer. the only thing that was shockingly confusing for my head was that exclusive OR thing. haha!

    good stuff!

    I got my card for like $200 something a few years ago it even has expandable memory(got like 512mb in there right now). I will say that it is definitely worth it, I previously had a RAID 0 and after it failed I never wanted to lose my data again so I got 3 WD Rapters in a raid 5. It has run great for years and I never turn off this computer. I do however need more drives...

    Hopefully I can save up for a 1TB :waah:

    The wha???

    Filled me in on a few things, like RAID 3 and 4 and RAID 1 only supporting 2 drives, I thought it could be more, like having two redundant drives.

    Nice article, just as my own raid card dies in 2tb raid 3 mode :( I can think of replacing it with something better.

    I had also come across this page which shows quite nicely the differences between raids with some animation. http://www.acnc.com/04_01_00.html

    Incidently if anyone can recomend a raid card that is known to work with vista, I would be happy to hear from you.
    (something like 5-8port, sata-II, pci/pci-e)

    Great article, but I do miss some examples of RAID implementations (like some good HW cards, Soft vs Hardware RAID [I think Linux here ;)]),...

    But nothing is perfect, and there's allways something somebody wants added :)

    Great article, but it would have been even better with some pointers on dedicated RAID controllers.

    The article is called "Understanding RAID" not "Implementing RAID"

    I think that RAID1 isn't really a good security measure. Just because you got such an array set up doesn't mean that your data is safe. An external HDD that is unplugged from the computer when not used is way more secure.

    From my experience, what has caused most data loss is HDD corruption either caused by bad drivers or Windows. RAID1 won't protect you against any of these :(

    Nor will it protect you from lightning strikes, Viruses or Hackers. It will only protect you against a drive failure. I'm sure most readers are aware of this, but just in case someone's thinking about using RAID1, keep it in mind, so you don't stand there with your beard in the mailbox when your computer has catched on fire :p

    Edvuld, you are talking backups... RAID isn't backup... RAID is protection against Harddrive failure... Safe data is data on redundant array + a good Backup routine.
