    Time to dust off the ol' floppy autoloader. Will only need to reload the hopper 20,000+ times.

    Ever heard of this wonderful technology called RAID?

    Well, with RAID offering more security, I still wouldn't call it a backup. Besides, they're yet to invent a RAID controller for USB drives ;).

    they've been using RAID internally in USB flash drives and external USB enclosures for HDD's for years. Hell, its an inherent tech in SSD's as well - two modules RAID'ed together invisibly to the sytem = fast SSD/flash drive.

    RAID is for speed, capacity, and/or redundancy. It is not a substitute for a backup.

    yeah, i remember playing dragon lair games that use 6 Floppy disk :eek:

    btw why seagate didn't release internal 3,5 inch HDD first ?


    not really if you use RAID0 or RAID5

    RAID0 for capacity and speed. RAID 5 for capacity and some redundancy. Your problem?

    He meant RAID'5 is usable as a form of backup.

    Yeah it would separate it from the pack with that feature out of the box. I still have no USB 3.0 devices myself. :laugh:

    RAID1 essentially IS a backup. All your data is stored on two seperate drives, any data written to one, is written instantly to the second. This is better than just backing it up to a second drive every few weeks, wouldn't you say?

    RAID0 is the exact opposite of a backup. It actually puts your data at a higher risk of loss.

    RAID5/6 is not a substitute for a real backup. However, it is better than no backup at all.

    I'm well aware of that, but that's not what I was referring to. Since the article was about a drive connected via USB (which I have a feeling everyone forgot ;)), I was talking about a RAID controller that would allow you to connect USB hard drives to it.

    RAID1 does protect you fully from a single drive failure, but it does not from electric shock (thunderstorm or PSU failure), which might smoke all your HDDs at the same time. That's what I meant by saying it's not a real backup.

    It doesn't need to be connected to a RAID controller to be used in RAID.

    Generally, if you are talking about using an external drive as backup, and the external drive is connected to the same power source as the PC(and they almost always are), then a lightning strike that takes out the computer and all the drive inside will also take out the external. Of course a solution to this is buying a good UPS, then you don't have to worry about the internal drives at all. A good PSU helps also.;)

    You could use optical media as storage, but those degrade over time and have a very limitted number of uses, and becomes quite expensive. I would be looking at 400+ DVDs to back up my 2TB+ of data, that isn't practical.

    No it's not. It's replication of the current state of the hard drive to protect against a single HDD failure. File corruption and deletions are replicated on both drives and something you cannot recover from unless you have .. a backup. :)
     
    Mussels says thanks.

    ^ That's generally how I view it. Could have 1 drive, could have X drives in RAID-51 with hot spares, but it's not a backup.

    thanks, you beat me to it. its really hard to get across to people that RAID is not a backup and never will be, and that it only protects against drive failure (not corruption/deletion)
