Introduction

I have discussed the perils of storage before. Like with money, the more you get, the more you want! And the storage industry has been all too happy to feed our growing need to stash our digital junk. Personal video players, media PCs, DVRs, and MP3 players all make it easier to generate large files (and lots of them). Add to that falling digital camera prices (and increases in resolution) and you now have a slew of digital pictures to store.

Yes, a lot of this stuff can be backed up to CD or to increasingly popular DVDs, but few people actually back up their data regularly. So, in the end, it comes down to a demand for bigger hard drives. Never mind the fact that the operating systems we use are approaching gargantuan sizes (yes, Vista, I am talking about you), and most computer games are in the realm 2-5 GB each. Our hard drives don't stand a chance. Or do they?

As platter densities have increased, we have watched our drives grow. 20, 40, 80, 120, 250, and now 500GB drives are in the mainstream. Larger ones are starting to show up, but the 500 GB variety is gaining popularity. All the big players are in the market. It is these 500 GB monsters that I have with me today. From Western Digital I have their Caviar SE16 (WD5000KS), from Hitachi I have their Deskstar 7K500 (HDS725050KLA360), and from Seagate the Barracuda 7200.9 (ST3500641AS). Each are SATA II, 7200 RPM drives with 16MB of cache.
