Hitachi to Release Half TB Drive Soon

I suppose the manufacturers picture lots of users buying a 10K RPM drive, sticking it into an under-ventilated box and getting a replacement a week later because it died from overheating.

      There's also that RPM is not the only way of making things faster. Basically, the performance of a hard disk is determined by 3 variables:

      Rotational latency: The time it takes for the disk to spin into the right position. That is, once the head is on the right place, this is how long it has to wait for the data to pass under it. More RPM translates into less rotational latency.

      Seeking latency: The time it takes for the drive's assembly to get into the right position.

      These two are often added up in the statistics. Solid state drives pretty much lack them. I'm setting up now a firewall that boots from CompactFlash on CF-IDE adapter, and it boots really fast despite a transfer rate of only 2 MB/s. Latency can add up to quite a lot.

      Data rate: The speed at which the drive reads or writes data once everything is in the right place. This is a function of the RPM and data density. More speed means the data passes under the heads faster. More density means there's more data per square inch.

      So, increasing RPM is one way of getting more performance. The other one is packing more data into the same place. Some drives have small platters for this reason. This also means that a bigger drive is often also faster than a smaller one, given identical RPM, platter size, and number of platters.

    Video files are generally at least two orders of magnitude larger than audio files, so while it has been feasible for the last few years to build an MP3 server to store all of your music (and now it's even feasible for most geeks to build one to store their music in a compressed, lossless format) the same hasn't been true for DVDs.

    But last night I was looking at the price for Hitachi's 400Gb IDE drive ($368 on at newegg.com) and figured that I could throw a pretty decent video server together for about five kilobux. I was thinking of getting a big case and power supply, eight of these drives and an Adaptec eight port SATA raid controller. Set up a Linux system, set up the drives and RAID controller as RAID-5 and you could get about 2,500Gb of storage, which works out to about 265 DVD images (assuming that each image was a from a dual layer disc and 9.4 Gb in size. Use SMB over gigabit ethernet to mount these images to your clients and then play whatever you like. Eight 500 Gb drives would give you about 3,200Gb of storage which works out to 340 images (making the same assumptions about the size of each DVD). I'm sure there are better ways of doing this, this is just what I came up with off of the top of my head.

    Note that this assumes that you're not doing any processing on the DVDs. With a tool such as DVD-Shrink you could increase the amount of images you were able to store by stripping out alternate soundtracks, extra features and even the menus. And with DiVX re-encoding you might be able to (I don't know much about DiVX so comments would be appreciated) reprocess the video streams so that they used less space but were not visibly reduced in quality. If I had a spare 5 kilobux to blow right now I'd build one of these as a mighty heigh-ho and fuck you to Bill Gates, Jack Valenti and all of the other assholes in Hollywood and have the pleasure of having a whole-house video solution.

With eight, you now have a good chance that one will fail every 6 months.

    After that, it's been a matter of building the drives with smaller and smaller pencils to write those ones side-by-side. When hard disks were first introduced, they used a standard #2 pencil sharpened down to the eraser, but eventually they moved to mechanical pencils, then realized they could use the mechanical pencil lead without the pencil at all.

    Today, special microscopic pencils can be built one molecule at a time. The "eraser threshold" (currently the smallest one is 0.00003 centimeters in diameter) is a key factor in manufacturing drives.

    It doesn't matter how 'good' DivX encoding is, Mpeg-2 is a lossy format. Since mpeg-2 is a lossy format, conversion to any other lossy format (including mpeg-2) will result in 'further' degredation of the video quality. in the case of DivX since DivX and mpeg-2 throw away different bits of data, the lossy conversion will be worse, than encoding from a lossless codec like HuffYUV.
    So to anwser your question, converting to DivX will result in both a generational loss, and some mpeg-4 specific loss of quality. Would DivX be smaller? in the same resolution the space saving is marginal*, you actually need to down scale resolution to achieve 'impressive' down scaling of files. Also, to make the 'best' mpeg-4s you'd need access to a lossless master of the video. Converting mpeg-2 to mpeg-4 is like taking an mp3 and 'converting' it into an ogg vorbis. And Granny Ogg Doesn't approve** of transcoding mp3's to .OGG.

    *= Properly compressed MPEG-2 streams are only 10% larger than comperable (read same resolution) MPEG-4 stream, however DVDs don't usually compress the audio at all, and generally don't compress the video as much as it 'could' be. Also, DivX 'scales' better than mpeg-2 making a 200% magnification mpeg-4 'appear' better than a 200% magnification mpeg-2...

    Anyway, one advantage I have noticed about DIVX over DVD is reduced bandwidth. You can get very respectable video quality from 1.5Mbps DIVX, versus ~4-5 times that DVD. Either of these is acceptable over wired connections, but 802.11a barely allows acceptable DIVX, and even 802.11g struggles to support more than a few DVD streams. But it manages several DIVX streams handily. There's also the issue of multiple seeks and STR rates on the RAID-array. So if you are in a family/group situation and you anticipate multiple simultaneous wireless access, recompressing to DIVX/XVID is a good option to reduce contention.

    Also, if you're setting up a media server, then Media Center is a good choice. Its ability to do on-the-fly codec transcoding and bandwidth downsampling based on client profiles is a godsend, as is its ability to control Tivo and uPNP media hardware devices on the network. Technical info here.

    3.5" hard drives often have four platters on which to store data. 2.5" hard drives usually only have one or two. In addition, the 2.5" hard drive platters are (obviously) physically much smaller than the 3.5" hard drive platters. For a given data density, not only do you have half the number of platters, you have much less surface area.

    As far as transfer performance, you can transfer the most data where the platter is spinning the fastest - on the outer edge. The 3.5" hard drives' edge spins that much faster than the edge of a 2.5" hard drive, so it's easier to get higher data rates.

    Spinning the hard drives faster and faster also builds up much more heat, and consumes more energy than slower drives. Laptops have a harder time coping with heat (it's not like you can just keep adding fans to the chassis), and battery lives are already short enough.

    There is also a lack of SATA interfaces for laptops. I don't know why this is, but you are faced with a chicken/egg situation - do you build SATA 2.5" drives if there is no connector for it? Do you build connectors for a hard drive that doesn't exist?

Anyone who remembers having to dial-in CHS values knows this, LBA is a godsend. The reason it wasn't implemented from the start was that it would shift processing (sector locating) to the drives themselves, which wasn't cheap to do in the eighties and early nineties. LBA has also been the standard for a LONG while now, and besides a minor bump in addressing size (which was painless as could be) it's an awesome and generous implementation.

    As for SATA, they DID get it right, they serialized and simplified the data stream and implemented it as ATAPI or a subset of SCSI for OS compatability. It uses a 48-bit LBA which (IIRC) tops out at 131,072 gibibytes, that's 128 terabytes! The hardware platform is also quite well thought-out, with room to grow, in speed, size, and scalability.
