Seagate Plans 37.5TB HDD Within Matter of Years 395

Ralph_19 writes "Wired visited Seagate's R&D labs and learned we can expect 3.5-inch 300-terabit hard drives within a matter of years. Currently Seagate is using perpendicular recording but in the next decade we can expect heat-assisted magnetic recording (HARM), which will boost storage densities to as much as 50 terabits per square inch. The technology allows a smaller number of grains to be used for each bit of data, taking advantage of high-stability magnetic compounds such as iron platinum." In the meantime, Hitachi is shipping a 1 TB HDD sometime this year. It is expected to retail for $399.

        Ok, so you are spending $399 for a 1TB drive. Compare this to a 400G (uncompressed) LTO-3 tape @ $50 per tape (price is good as of yesterday when I ordered another 100 LTO-3 tapes). Your drive is about 3x as expensive.

        The tape is still cheaper. It also takes up less space on my shelf and I can drop it and not worry about loosing anything.

        I am looking at these drives for the front end disk array that I use in my d2d2t setup (disk -> disk -> tape). Given about 40 of them I can keep 2-3 weeks of backups online in the disk and then destage to tape for the offsite vault and archive backups. This way restores of recent data is almost instant (no need to mount and seek to the spot in the tape), but the old archives cost me less and I save on power and cooling (the tape library expansion modules take no additional power. its just a shelf with tape slots).

        Its not an either/or choice. Most folks with any real amount of data to backup use both.
    • Backup tape density grows as well. LTO 2, which my company uses can store 200N/400C GB per cart. The truth is, our source code is so easily compressed that we get 500N/1000+C GB per cart when dealing with it. LTO4 should be out soon. I can only assume that in 5yrs tapes will be easily dealing in 20TB uncompressed.

      ...the tape will be in a cartridge that holds a spool 65cm in diameter, holds approximately 600TB (1200TB w/ compression) and will require an autoloader that eats at least one rack for the entry-level 8-tape kit. /dev/nst0 will weigh in at 38kg, and cleaning will require a tape w/ 6000-grit sandpaper in place of media.

      All BS aside: you do bring up an excellent point. I'm a guy who has to do backup/recovery, and I've found that even a fully compressed LTO-3 will barely --just barely-- hold up to 1.2TB if you rig it right (by combining hardware/software compression, and the love that Bacula gives it (though admittedly sparse file handling most likely has inflated the reported amount of stuff).

      Anyrate, that boils down to --maybe-- two full HDD's if the two are 500GB SATAs.

      The good news is, after you pare down the crap you really don't need to backup, it usually isn't all that much for most companies. You can safely exclude out most of the OS itself for starters... w/ kickstart on RHEL and a .ks file that replicates what you've got on a given server (partitions, packages, etc), you can cut a LOT out.

      Even more good news - if you get up a monster RAID array of similar drives (full SAN kitting or just attached to a big ol' server, no biggie), you can use it instead of tapes for most of your day-to-day backup. Then latch your tape drive or autoloader onto it and only commit to tape the reallly vital stuff that requires a long retention period. Most backup software suites (even Bacula) support writing to file as well as tape, so this shouldn't be too big of a problem for a sysadmin if s/he knows what s/he's doing.

      Adaptation and all that.

      But then, most of the servers in my care consist of a pile of RAID5'ed SCSI drives that range 36-140GB in size... and I doubt that most of them will get much bigger before it's time to replace the servers themselves. Just because you can get monster capacity on a single drive, doesn't mean that you need to or even want to.

      Now if I already had a monster robotic multi-drive tape library running 24/7 now, and the boss wants to up the HDD capacity on a given pile of servers because he pretty much has to? Yeah. That would require a lot more thought and planning, and at that stage of the game a disk backup solution similar to what's been outlined above would be big and ugly, but would pretty much be what you're stuck with having to do.

      ...at least until they come out with the LTO-48 ;)

        Disks DIE. Tapes rarely do (comparatively). Tapes, although slow and linear, are incredibly durable.

        HDDs aren't exactly volatile, but they are a heck of a lot more susceptible to corruption and failure due to the fact that you have both a magnetic storage medium AND the circuitry to power and control it on one device. And if one dies, you're pretty much fucked. A tape is only one of these, and is simpler and more reliable.

    Ok, so on the more general point of high capacity 3.5 inch drives, Does anyone really need these? In my experience, PC hard disks are already way too big. A friend of mine uses his 100 gig drive for some emailing, websurfing, playing a few games, and music playback. Last time I checked his PC it was over 85% empty. And most of the space that was consumed was the O/S.
    All a bigger drive gives joe average is a longer defrag time, and longer search time. I'd hazard a guess that 80% of current domestic end-user drive space is currently empty.
    Sure, many slashdotters will have filled their disks with all manner of stuff. I'm a developer, and the obj files alone for games stretching back 10 years certainly take a up a huge chunk of my disk, but we aren't average joes.

My 1.2 Terabyte RAID array is full, and I am currently wondering how the hell to add more storage and migrate the data without simply building a whole new machine.

      The innovation in capacity and density is driven by the needs of enterprise users, and atypical users like me. The advances that come of it are then incorporated into lower-end drives as well. The reason that you start to see 100GB drives being the lowest capacity you can find is not because nobody could get by on less, it is because it would cost more to keep producing drives using the older technology -- each leap forward in drive technology has to be accompanied by retooling of manufacturing equipment and process, and it doesn't make a lot of fiscal sense to keep producing lower capacity drives if they cost as much or more to make as a newer one with higher capacity.

      The same technology (which fundamentally is increasing the density of the data on the platters) can be used for making physically smaller, less power consuming drives.

This could go into a device like a HD camcorder, and have space for plenty of full quality uncompressed video.
    • I think the market is right around the corner: high-definition TV.

      The PVR market has been crippled in recent years because of market confusion, and compatibility problems (will my TiVO work with my cable box, etc.), plus competition for consumers' money by HDTVs themselves.

      Once people get done buying their HDTV and paying off their credit cards, they're going to start looking at PVRs. I think that's a market that's probably going to explode in the next 5-10 years, even more than it has already. I also think you're going to see PVR functionality being built into the 'standard' cableco boxes, rather than as an upgrade. (Not that it will be free, they'll just charge everyone for it.)

      High-def TV takes up a lot of space. That means if you want to have significant PVR functionality, you need to have a lot of local storage. 37.5TB, or 300Tb (aka 300,000,000Mb, if we use the 'marketing department' definitions) would be about 4,340 hours (180 days) of 19.2Mb/s HDTV. While that seems impossibly huge, I could imagine a future PVR using it as local cache: constantly downloading and storing programming based on your preferences. Add in a big HD movie library (say the contents of your local Blockbuster) and you can give the customer the impression of many simultaneous channels, even if they only have a relatively narrow pipe. (Narrow being 1 HD channel at a time, or a 20Mb pipe -- fat by today's standards, granted.)

      Content always expands out to fill the available capacity. I remember when I first heard about the development of DVDs, back in the early 1990s. They seemed pretty ridiculously big then, too. Now I have stuff that I can't back up to DVDs, because it would be impractical to split it among so many discs as would be required. (Apple's Aperture doesn't even try to have a backup-to-DVD option, it's designed strictly to work with removable hard discs as backup 'Vaults.')

      There was a time when people thought 20MB removable media was more than a single person would ever need, though we might look back and laugh. There's going to be a time in the future when 40TB looks the same way.

      But yes, price is also important. The drives I bought were in the "sweet spot" where the cost per GB was low. The higher dens
    • Actually a larger hard disk can only help with defrag times and won't effect search times (assuming the same amount of data)

      But your point on Why Innovate on capacity is a good one--moreover why innovate only on capacity.

      How about a hard-drive with built in RAID? Spread writes across all platters so that if one glitches you get the others. Still, this is not optimal because you can't replace a platter--but still, can we work on using that extra space to improve reliability?
  • Gigantic hard drives are great and all, but I'm especially wary of anything Seagate releases that's new.

    My first large hard drive was a Seagate 120GB 7200.7 that still works to this day. It's one of my favorite drives and has never let me down.

    I needed more space so I buy the then top-of-the-line Seagate 300GB 7200.8. I believe this was the first to use Perpendicular Recording Technology. I backed up all of my precious data on there and went about my business, only to realize that after 8 short months, the

      The 7200.8 does appear to have issues. The Storagereview reliability database has it ranked in the 31st percentile reliability-wise, although the limited number of entries (only 220) might be skewing the results a bit. The 7200.7 on the other hand is in the 89th percentile with nearly 800 entries. The majority of Segate products listed in the database with a statistically significant number of entries are ranked in the 90+ percentile for reliability. Personally I have installed about 300 Segate HDD's in ser

    • Storage space wise we seem to be getting there a couple of hd generations even if were not there yet (in terms of affordability). Brain has around 10^11 neurons (one terabyte is 10^12 bytes, SI standard). Each neuron can make connections to thousands or ten thousands other ones. Even with some clever mapping of connections I'm guessing we would need something in the petabyte scale.

    This drive will not be 1TB. It's another scam. Rather than actually be a 1GB drive, as in 1,099,511,627,776 bytes it's a 931.32~ GB drive as in 1,000,000,000,000 bytes. Yep, 69GB short of a Terabyte. It's just falsely advertised as a 1TB drive.

    Hard drive makers:
    Kilobyte = 1024 bytes
    Megabyte = 1024 kilobytes
    Gigabyte = 1024 megabytes
    Terabyte = 1024 gigabytes

    Label your fscking drives accurately.

    • Eh, close enough. Who's really going to miss that missing 69GB, anyway? That's barely, like a small shelf of DVD movies. A pittance barely worth mentioning. I routinely lose 69GB in the wash. Never underestimate the bandwidth of a guy wearing sneakers and cargo pants with a buttload of flash drives!

        While the names may have been officially changed in 1999 and many of us having been working on computers for far longer than that, that's just old habits dying hard - the real problem is one of a perception.

        Windows (and I assume Mac OS?) continues to display file size in terms of base 2, and HD manufacturers have bought into this base 10 thing (to make their hard drives sound larger).

    Here is a Capacity over time [wikipedia.org] chart.

    Just eyeballing the straight line, this chart shows capacity doubling every 21-22 months or so. Lately things have sped up a bit.

    I don't think someone would announce a drive that was 9 years away. It looks like things are moving at a faster clip, faster even than the 18-month "Moores law" that applies to transistors.

    Here is the important question on everyone's mind:

    Which is doubling faster:
    Drive size or the yearly porn production rate?
