How Data Storage Has Grown In the Past 60 Years 100

Posted by timothy from the megaleaps-and-gigabounds dept.
Lucas123 writes "Imagine that in 1952, an IBM RAMAC 350 disk drive would have been able to hold only one .MP3 song. Today, a 4TB 3.5-in desktop drive (soon to be 5TB) can hold 760,000 songs. As much data as the digital age creates (2.16 Zettabytes and growing), data storage technology has always found a way to keep up. It is the fastest growing semiconductor technology there is. Consider a microSD card that in 2005 could store 128MB of capacity. Last month, SanDisk launched a 128GB microSD card — 1,000 times the storage in under a decade. While planar NAND flash is running up against a capacity wall, technology such as 3D NAND and Resistive Random Access Memory (RRAM) hold the promise of quadrupling of solid state capacity.

      To be honest, it wasn't a terrible unit of measure early on, especially with things like mp3 players, cameras, and SD cards.

      Yes, an mp3 can vary in size dramatically, but there is a fairly consistent average. Most mp3's are going to be somewhere between 3 and 10 MB. That's close enough to give a rough estimate of how many "songs" you can fit on your mp3 player.

      It was a reasonable measure for a non-technical person because it was a capability they were actually concerned with. These days it's silly though, because the number of songs you can fit on even the cheapest walmart mp3 player is in the "probably more songs than you will listen to in your lifetime" kinda range. It's turned into a big cool sounding number rather than a useful piece of information.

                Hard disk drives use sectors which at some basic level have to be addressed by a powers of two binary addressing system. This means that no matter what else you do with sector sizes or block sizes, the binary counting system *always* comes into the picture.

                Right, they're addressed using LBA48, which happens to be encoded in binary because that's how we build computers. That doesn't imply disks naturally only support powers of two for sector counts or sizes - they evidently don't.

                CDs and DVDs have 2,352 and 2,418 byte physical sectors. Some Fibre Channel HD's support 520 byte sectors, and of course like optical discs all HD's have substantially bigger physical sectors internally for error detection and correction. A quick sampling of some of my HD's reveals drives with 732,566,646, 3,907,029,168, 500,118,192 and 312,581,808 sectors (at least they're all even?).

                Ethernet is even more flexible, supporting any frame sizes between 64 bytes to over 9KB, hardware permitting. Note 9KB is not a power of two.

                Wrong, and wrong again. *All* computer peripherals transmit data to and from computers encoded in binary signals. It means that all computer based addressing is essentially binary

                Um. Yes, the numbers are encoded in binary. No, this doesn't mean computers can only handle number maximums that are a power of two. Memory happens to be like that because it has to be insanely low latency and simple bit operations like masking off the lower portion of an address is very efficient, but not everything is so restricted.

  • 2.5" Hard Drives have been stagnant though. While SSDs have been steadily improving, the biggest 2.5" HDD you could get a few years ago was 750 GB, and now it's still just 1 TB.

    • I assume you're talking about 9.5mm drives because there have been 2tb 15mm drives for quite a while. And Samsung recently released a 9.5mm 2tb drive but they're only selling it in portable cases for some stupid reason.

  • I've got more storage now than I ever thought existed when I was a kid. I have a 32tb fault tolerant array in my RV. My little pocket camera has 32 gigs. So does my phone. I've got 4 2tb drives I cycled out of my array that are just sitting in boxes because I have no use for them.

  • ....When a 20 MB Seagate ST-225 hard drive at US$499 including controller was considered a good deal--and this was way back in 1984! Today, I can get _three_ 3 TB hard drives and still have US$50 left from that same US$499.

  • I paid close to $300 for an 80 Meg scsi hard drive while my friend had a 200 Meg hard drive the size of a dishwasher (what most thought it was) for his Unix.

    I kept backups on 3.5 floppies (one of three) http://i42.tinypic.com/2hwpx82... [tinypic.com] , then on 700 Meg CD's upto Blueray DVD's that hold some 24 Gigs. Only one BlueRay DVD made it though with no errors, yet no data loss.

    It's cheaper, more reliable, and a damn lot easier now to make my back-ups to USB hard drives and sticking them away until needed.

    For a real insight into increased density of storage, look at the enterprise level SANs. 10 years ago 10TB of storage took up several racks. I just installed a 3PAR array. It's configured for 60TB and takes up 1/4 of a 42U rack, and uses 1/10th of the power.

    in 1952, an IBM RAMAC 350 disk drive would have been able to hold only one .MP3 song

    Where is that 1952 date coming from? It wasn't commercially available until about 1956, in limited quantities, and as best I can tell, it's from a research project that started in 1953 with the goal of testing the various storage possibilities, disk being one of many. Thus, it's not likely that working prototypes would be available until about 1954 or '55.

  • Unfortunately, backup capacity does not scale as storage does, network throughput being a common bottleneck.

    by Anonymous Coward

    The larger disks, the more data corruption. I quote the wikipedia article on ZFS:
    "...The main problem is that hard disk capacities have increased substantially, but their error rates remain unchanged. The data corruption rate has always been roughly constant in time, meaning that modern disks are not much safer than old disks. In old disks the probability of data corruption was very small because they stored tiny amounts of data. In modern disks the probability is much larger because they store much more da
