IBM's "Pixie Dust" Drives Improved 322
jeffroe writes "Infoworld has an article stating that IBM has enhanced it's 'Pixie Dust' technology yet again. The areal density has improved to 70gb per square inch! Apparently that means 80gb drives for laptops." IBM's also predicted hard drives to have 100gb per square inch by 2003. Storage space just keeps increasing.

There is simply no reason for Joe Shmoe sitting at home playing Sims/Unreal/Quake/etc to blow so much money on SCSI since the full potential of it will never be realized.

(The hardware compression is not good on decently compressed files, and actually ends up eating more space than the raw data would.....)
So, for 80 gigs (estimation), you need 8 tapes. Minimum 10$/tape, that is 80$. May as well buy another drive; let alone the speed of backup / restore and the tape change duties.
I've won 2 bids on ebay and now have 30+ tapes, brand new, for around 60$ total investment. Now I've got enough tapes to do 2 full backups of my server, and have some spares for incrementals and "oddball" machines.

I find the ATA RAID1 solution more elegant. The only issue that bites is that you can't do historical backups or pull data off the drive you deleted two months ago but now decide you need (it's happened to me). But disk mirroring is realtime and provides an easy way to cut over to the other disk (as opposed to reformat, reinstall, restore with tapes)

My company is run out of the house next to mine, and we have a cat5 cable running under the driveway to connect the two. This allows me to have a backup server at home that provides automatic offsite backup. I put together a machine that includes a 2ghz Athlon and two 120 gig 7200 RPM drives in a RAID array for backup. The box runs Gentoo Linux [gentoo.org] and uses BackupPC [sourceforge.net] for automatic unattended backups.
Of course, most people don't have the extra cash for that lying around (I had the business credit card, hehehe) but it is certainly easier and more cost effective than tape.
BTW, the backup server backs up around 10 machines (mix of Linux and Windows) with around 120 gig of data. It keeps up to two weeks of backups at a time (two full backups and twelve incremental backups). Current HD usage is about 33% due to compression.

UT2k3 is 2.4GB, more if you have some custom maps. Except UT2k3 also wants the CD; you don't want to constantly swap in originals, so you rip the play CD and mount in daemon tools. That's over 3GB for one game.
NOLF 2 is ~1.6GB, plus easily 50MB+ of savegames, so let's say 1.7GB, plus daemontooled CD, that's 2.4GB.

Email: I recieve a tonne of it, and I keep all of it, too. This year I chalked up 1.3GB.
Windows: 1.8GB here. Oh, and another 1GB of swap.
Backups: I mirror my ~/ and various other dirs to my Windows machine, that's another 1-2GB of junk, easily.

Music: I'll admit I don't own much, and the RIAA probably would be rather irriated at my collection, but what I do own, I rip; the CD's barely get taken out once, purely because my computer is my sound system, and OGG's are the most useful format for me. 50-100MB per CD, multiplied by however many CD's I might own. 100 CD's isn't uncommon; 5-10GB, assuming I use OGG and not FLAC or another lossless codec. 20GB+ if I go lossless.
Movies: Ditto for MP3's; although legitimate use is probably closer to "If I want to make my own edit of I want the space to do it in". 10-15GB, easy. Plus maybe I want to keep those 6GB VOB's on my HD so I don't have to hunt for the DVD's and risk damaging/exploding them
8 DVD's * 6GB = 48GB. Oops. A friend of mine owns over 150 DVD's, I'm sure he'd love a couple of TB to store them in rather than hunt around his shelf for them.
TV: Let's not forget TiVo and friends. Hands up who wants multi-TB HD's for their PVR?
Alternate OS's: When I want to try out RH 8 or FreeBSD-CURRENT, I want the disk space to try it out. 5GB (at least) for the spare partitions.
Cache: 3 browsers, each with 200MB+ cache dirs. 600MB of tiny files that probably bloat to 800MB easily. I might like to give squid half a gig or more.
Source code repositories: I have 1.2GB of tarballs and source direcories, most aren't even full CVS repositories.
Versioning: I dream of a time when my filesystem is one big version controled repository. I want to keep every modification I make to my HD, at least in certain directories. Multiply current requirements by about 100.
That's about 55GB there, and I've not even got onto applications or central storage for all my digital data, or filesystem version control, and my requirements are only going to get bigger while I'm allowed to purchase permanent licenses for data.
Conclusion: Relatively average users could quite happily make use of multiple TB's of quiet, reliable, backupable, rollbackable and relatively portable storage.
