Perhaps we'll see cheap hard drive carrying and storage cases catch on soon, or just differently specced drives specifically geared for archival purposes. Possibly they will have lower performance, but be more reliable and shock resistant?

DLT7000 (30GB/tape)?
VXA-1 (33GB/tape)?
AIT-2 (50GB/tape)?
M2 (60GB/tape)?
VXA-2 (80GB/tape)?
Ultrium (100GB/tape)?
SDL320 (160GB/tape)?
Ultrium 2 (200GB/tape)?
Note that those are all *native* capacities. You could theoretically back up one of these high capacity drives to a single tape, depending on the data you're storing.
A library would be a much better option, but even that isn't necessarily beyond the reach of even small businesses. A VXA AutoPAK 1x7 with a native capacity of 560GB is only $3,299 from Exabyte.
The problem with backup is largely one of what *home* users can do.

It's relatively cheap to put up a nice raid-5 external scsi storage chassis -- about 1Tb of space would cost slightly over $10k. Most research groups can easily come up with this amount of money, however we end up turning them down because we cannot afford to back up that much data. Tape drives are NOT cheap. Tapes are NOT cheap either. Moreover, while drive capacities have been increasing steadily, tapes haven't been able to catch up at all -- AIT3s are currently 100G uncompressed, and with the data physicists like to produce, we cannot rely on the 2:1 compression to hold true. To be able to back up 1Tb of data we would need at least 8 tapes and at least an 8-tape changer.
Add to this 30-60 AIT3s for daily backups (~$5k), plus 8x12x3=288 AIT3s for a 3-year monthly archival storage, and you quickly run into SUBORBITAL amounts of money which research groups expect us to come up with. I mean, we're talking ~$10k for the 8-tape changer, and ~$25k for tapes.

For VXA-1, tape costs about $2/GB, retail price (you may be able to do better).
For DLT-IV, tape costs about $1.4/GB.
For VXA-2, tape costs about $1/GB. About the same for AIT-3.
If you can find decent and not too expensive hot-swap drive carriers, those 320GB drives at $300 USD almost start looking good for backup media themselves! They could be close to $1/GB if the carriers aren't too expensive.
All that above was uncompressed storage. Compression can cut those prices in half if you can use it with your data.
HDs can backup data real fast, especially if you're using rsync. The problem is the drives themselves are more fragile than tapes. Though you can easily damage a tape by dropping it too (especially DLTs). Tapes are a bit better in terms of temperature range. Dunno about long-term archival storage.

I'd love to replace them with 320 GB drives, for a cool 1.5 TB or so of space, and, frankly, the 3ware RAID controller and the ATA100/133 drives attached to it are more than fast enough for all of my video capture, editing, and rendering needs. 20,000 RPM wouldn't just be superfulous, it would probably be detrimental in terms of the expected disk life and heating issues within the case.
Re:Can we PLEASE work on the spindle speed? (Score:2)
For your aplications that need speed, you don't want these devies. You want 'solid state' hard drives (aka gobs of RAM on an IDE/SCSI bus).
Besides, while I havn't run the numbers, I'd be willing to bet that a single 15k RPM drive can't fully utilize an ATA133 bus. (it may be able to burst that high, but I doubt it can sustain that rate in the real world.)
That's why scsi systems that are at 320 megaBYTES/sec usually have 14 devices on them.

Not spindle speed. You can put the newest fastest 15K RPM SCSI drive on an 15-year-old computer with a SCSI-1 bus. You probably need a SCA to 50-pin Centronics chain of adapters, and of course the drive will fall back to single-ended mode as opposed to low-voltage differential, but it works.

Faster seeks! Reduce the rotational latency by spinning the platter faster and you'll have to wait less time for the data to come under the head.
If you do streaming video, seek times may not matter much to you. But for many applications which have large numbers of small files, seek times are usually the limiting factor. There's much more than just MB/s when it comes to disk performance.

No, but you can put 48 (or 480, or 4800) SCSI drives outside the PC-clone case. This isn't an option with IDE, where cable-length limitations hit you real fast.
I agree, no desktop user needs that many drives, and few server platforms truly need that many either. But it's available for those who do.
Again, I'm no SCSI bigot; all my personal systems are now ATA. But there is a very real market segment where ATA is not an option, either for RPM or drive number/cable length reasons.

320GB is a nice jump. Unfortunately, the initial price is way too expensive. It seems like every time hard drives get to an affordable level, my collection of mp3's shoots past it. At the moment it's at 700GB, and they are all archived on 1100 cd-r's
At the moment, I'd say the best deal is 80GB hard drives at about $80. But a hobbyist can't afford 10 of those.
Another phenomenon I've noticed is that the more you have on a hard drive, the faster you can set up trades. Which just makes your collection grow even faster. Even if I had all 700 GB of mp3's on hard drives, it just means I would be able to double the collection in a month or two. Enough hard drive space is thus impossible to attain.

No, they aren't. MTTF is Mean Time To Failure, where "mean" means "average", get it? Having a drive that, theoretically, lasts a hundred years is meaningless from an engineering point of view. Reliability figures such as that are used to calculate how much redundancy one needs to make sure the system as a whole will not fail, within a given margin.

Traditional fair use archives of digital entertainment? Like movies and music? I want a home server with all my CDs and DVDs archived on it so I can send the data to thin-clients around the house, like STBs. 160 GB barely is enough for my CD collection, and boy, do DVDs fill up a disk quick!
To argue that this is wrong because of defeating the DVD CSS in a DMCA-defying act is like arguing it's suddenly O.K. to roast Jews because Nazis in power passed a law saying so. (Yes, yes, Godwin's Law, and the concentration camps' purpose was somewhat hidden from the populace, so the analogy isn't perfect). The point is just because something is a law does not mean that disobeying it is wrong, or that obeying it is right. I provide a proof, in extremis, by example. Because this is possible it is reasonable to question whether any law is correct to follow or moraly bankrupt. Extreme and less extreme laws differ only in the difficulty of answering that question, and not whether it should be asked.
The DMCA, in many ways, is a horribly insidious law: it sets the precendent that something that can be used to harm is now illegal. I'd venture that anything can be used to cause another harm. The DMCA sets to stage for rendering all activity illegal, at the whim of prosecution and judge. Well, fuck, if everything is now illegal, I've got a lot less incentive to care if I obey the law -- obedience to arbitrary law suddenly becomes a very weak proxy for a moral compass.
The kind of person who thinks something should be enforced "just because" it is the law, is the same kind of person that stands around when innocent people are killed by the state. Not the kind of person I want standing near me.

Not as true as you might think (Score:2, Informative)
Let's look at transfer rate first:
If you double the density how will this affect transfer rate? Let's assume that the increase (it's doubled) in density is achieved by having sqrt(2) times more tracks and sqrt(2) times more bits in each track - a fair assumption IMO. The transfer rate of a new 5400 RPM disk compared to an old 7200 is then (5400*1.41)/7200 = 7636 / 7200 = 1.06. The 320 GB disk's transfer rate is 6% better - not very impressive.
The theoretical average seek time for the old 7200 RPM drive on the other hand is 1/(7200*2) = 6.9 ms compared to the new disk's 1/(5400*2) = 9.3 ms. That's 25% better - which I think is quite a lot.
In real life I think that you'll find an old 7200 RPM drive quite a bit snappier than a new 5400.
