High Density Storage

Charlie Engasser wrote in to tell us about 216 gigabytes hard drives over at Seagate. Uses "Optically Assisted Winchester" (OAW), which "augments traditional magnetic read/write techniques with a laser to allow positioning so precise that it can store over 100,000 tracks across one inch of drive surface". I guess it just means in a few years we'll be able to do with video what we do today with sound. From this page.

      I wondered about this as well. With a drive of this kind of capacity I would think doing FAT lookups would be just brutal. Already for most servers it's better to go with 3x9 gig drives then buy 1 27 gig drive, and use striping. It's an awful lot of data to lose if your 200 gig drive fails! (Of course, you can always mirror...) I'm beginning to think we're starting to push the boundaries of magnetic storage as far as they can be usefully stretched. Well. Perhaps not.

      I suppose it should also be examined that a higher density doesn't necessarily mean they'll build a hard disk of that capacity - they could just make existing hard disk capacities, 9 gig, 20 gig etc. on hard drives that are physically a whole lot smaller! Of course, I wonder what the new system for aligning the heads does to power consumption... it would be nice to get 20 gig laptop hard disks. :) Hmm, it'd be nice to have a laptop, period. :)

      Something I've thought about as drives get larger would be dividing the FAT and data segments. Use solid state circuitry to store the fat - instantaneous lookups - and then the platter holds only data. This way, the heads don't have to scan back and forth while doing lookups.

      Oh goody, my pet peeve...

      First off, I'd like to point out that brains are fundamentally different in every way from digital computers: storage, processing, etc. Estimated about brain capacity in computing terms tend to be based on enormously flawed concepts, like guesses about how many bits are stored per neuron. (Short answer: none. The information is stored in the network, not the nodes.) I can't imagine what playing 20 questions has to do with memory; as for 100bps I/O, consider that you're brain is processing (and storing, though perhaps not permanently) everything in the environment, not just what you consciously perceive. (This has been studied, but I can't find the references.)

      Second, even assuming you could measure brain capacity this way, would it be meaningful? Is audio stored at .wav or mp3 level compression? Is visual data stored as complete frames or more like mpeg? Is the data actually compressed for storage, or is the (arguably) poor quality of memories a feature of how they recalled?

      Anyway, a few months ago I heard (several times, can't remember where) that the capacity would have to be more like 10 to 100 terabits, based on how much people can recall over a lifetime. I don't believe this either, but it seems much closer than a couple gigs.
