The Evolution of Hard Drives – 1979-2011 [Pic]

Next year’s model is already in the picture, somewhere between pixels 585 and 586 in the bottom right corner.

  1. goin even smaller and smaller.. though 2.5 in harddrive have only caught on in laptops and low power applications.. the 3.5in drive is far from dead especially in terms of capacity!! i can see it out-living 2.5 drives which will die and be replaced by SSD

    • thats not true.
      the 3rd smallest is your 3.5in desktop harddrive and is currently available in capacity upto 3TB.
      the next smallest is only up to 1tb.

      i dont know what the capacity of the smallst drive pictured here.. but place my bets on it being nowhere near 1tb.

      What is true to say is "The smaller they get, the faster they get" though the 2.5 drives are relativly poor on performance! lol

  2. If the big beastly 1 that's nearly as old as me was re made using modern techniques and materials i wonder how many TB's could be squeezed onto discs that big…

  3. Over 30 years, and they still look exactly the same as they did back then.

    Sheesh, you'd think someone would have some kind of innovative burst since then. With Native Command Queuing (sp?) and 4kb sectors, why the hell haven't we seen dual-head hard drives yet (on opposite sides of the disc)? That would effectively double transfer rate, as each head stack could read alternating tracks at double the speed, seek to different positions at the same time and perform parallel read/write… effectively doubling drive speed in every possible way.

    Am I SERIOUSLY… SERIOUSLY the first person that's thought of this?! Come on WD, hire me already. >.<

    • Funny, I just found that the idea's already been thought of, but idly dismissed. Evidently Seagate owns the patent on it, so they would need to be the ones to produce such technology. Well, they need to get on it already! The time is right for it – HDD processors are already blazing fast to track and coordinate single-actuator systems that are in use in all hard drives to date… and with everything "dual" these days, and SSDs mopping the floor with hard drives in terms of performance (software is STILL optimized for hard-drive use, not Flash), there seems to be no better time than to get into the game with dual-actuator hard drives. Maybe the time wasn't quite right in 2009 when it was first "revived", but a good amount has changed in the past few years!

      Here's that Tom's Hardware "Exclusive" on the dual-actuator/head hard drive concept… http://www.tomshardware.com/news/seagate-hdd-hard
      … with patent drawings and everything of exactly what I had on my mind, too! Something about thinking alike…

  4. In the early '80s I worked for Control Data Corporation, for the Md. State Lottery. We had three 80 Meg and two 300 Meg disk packs on each of the 3 CPUs, (1 online & 1 back up running, and the 3rd system offline, rotated daily), with about 5 and 12 single sided disks in each unit, (long time ago..+ or – # of plates). The packs screwed into a floor unit that measured about 2 foot x 2 & 1/2 foot x 3 foot, and were themselves approximately 6 inches and 10 inches high x 15 inches in diameter-about the size of a medium pizza, …lol, encased in blue plastic casings with a T handle that was also the locking and unlocking mechanism after insertion into the unit.

    This halfway dead VAIO I'm using has more memory left on it's screwed up internal HD than the whole computer room had…………….lol!

  5. I remember walking by a platter (which had been scared by a disk head) in 1981 which was around 3 ft in diameter.

  6. I want to see how much we can fit on a modernized version of that massive hard drive. Estimates anyone?
