Google travan drive or tape drive.  I have a seagate travan drive I bought in 1996.  It moved like watching grass grow.

RAID, my friend, RAID.  Get ten or more of these running in a raid format, and speed stops being an issue.

 you don't understand the basic of how it works do you?

How are you going to make a RAID array that has to output to a single casset. Your basicly saying "if i RAID 10 DVD-Rs together i can create one Disc in seconds!"

By 'it', do you mean I don't understand a specific type of RAID array (pick one) or tape drives?

I know what I am talking about because I have seen it done.  Not sure where you pulled the whole DVD-R thing from? Because I have to agree what you said about DVD-Rs makes no sense.

 it's recording data onto magnetic tap, a removable storage.

You can't just RAID five tape decs together to write ONE tape.

Can you show me where I said "one tape", cause I'm looking back and I don't see it.

What I am talking about: You stripe across 10 (or more, or less) separate tapes.  They, in effect become one large tape (in effect, in theory, but they do stay in their individual drives, duh). You are simultaneously writing to ten tapes, reading from ten tapes. This increases your read/write speed and drive size substantially.  If you are worried about losing data, you toss another couple tapes (in different drives, do I need to say it) to do an overnight backup on the whole array.

Yes, it would be a bad idea to remove one of the tapes... that would be messy. But you would have a stupid amount of storage, and it would be stupid fast.

If you don't belive me, just Google: "Tape Drives RAID".

What he is saying, poorly I might add, is that you can't RAID sequential media. Redundant Array of Inexpensive Disks. The whole idea of trying to stripe across a tape array is terrible, just terrible.

 Thanks for the translation, yeah, you got it. A Tape Raid is just a ugly, bad, idea. Sure it CAN be done. I mean we could do a RAID of BlueRays and only have x% of data on each disc. You CAN do it but it's just a horrrrible idea.

Thank you for the clarification.  This article: http://www.enterprisestorageforum.com/continuity/features/article.php/3607321 says basically the same thing.

CORRECTION: What I thought I had seen before (tape drives in RAID), was reality a backup to multiple tapes at the same time, not an actual RAID array. Apologies.  Head-desk.

I may be wrong, but I believe it is the speed at which these devices work that makes them impractical for home use. Companies that run these solutions pay people to sit and switch tapes, and if memory serves, they are not fast.

Not only are they painfully slow, they tend to be delicate. Maintaining tape archives was part of my job a few years ago. Broken cartridges were not uncommon.

Unless you have truly epic amounts of data, the best way to back up a hard drive is with another hard drive. They're cheap and they work.

a company needs to come along and make this for home use and make it affordable. As more people are putting EVERYTHING valuable in digital format (that can be put into this format) it is becoming harder to do a safe backup just because of the cost. One tape could take care of a family for a long time.

Would be impractacle for home use though.

 Why? Is it just write once, no apending?

Its because they are essentially cassette tapes with large storage capacity. Pretty much means they are beyond slow at writing and retrieving data. They are only good for keeping large archives of data that you don't need very often.

 yeah but a inexpensive, removable, large capacity backup seems idea for homes. Sure it isn't fast but home doesn't need to have fast backups.
