Seagate Pushes Hard Drive Platters to 160GB

TheRainDog writes "Although perpendicular recording has yet to make its way into desktop hard drives, Seagate continues to push platter densities the old fashioned way. The company's 160GB platters have the highest areal density in the industry by over 25%, allowing Seagate to create a 160GB Barracuda 7200.9 hard drive that uses a single platter and costs under $90. The single-platter design has lower noise levels and power consumption than multi-platter designs, and a lower probability of a catastrophic head crash. Higher areal densities also allow the drive head access the same amount of data over shorter physical distances, improving performance dramatically in some instances. The Tech Report has an in-depth review of the 160GB Barracuda 7200.9's performance against eight competitors from Hitachi, Maxtor, Seagate, and Western Digital."

    Some may argue that a drive like this is overkill, or even wasted, on an old machine but people like me - who spruce up old P3s bought on eBay by adding faster drives and RAM to make economical web PCs for friends and family - would love to get our grubby little mitts on a drive like this !

  2. Risk of High Data Density by Bender0x7D1 · · Score: 4, Insightful

    My concern would be that anything that could affect a portion of the disk would destroy more data. I know scratches that aren't noticed on a CD can make a DVD unreadable and, while a drive platter may not have the risk of scratches that optical storage does, the general idea is the same. A physical failure, such as a head alignment issue, that wouldn't be noticed with lower densities may be a factor with the higher densities.

    Now, I don't have a solution to the problem, but I just want to point out that getting full performance out of something can raise new risks.

      Scratches on optical media come from handling the media, this happens at all sorts of velocities and thus there are a wide variety of scratches with varying degrees of damage.

      Scratches on Hard disks come from the freakin' head smashing into the disk while it is spinning at 7200rpm, there is no such thing as a benign head crash, when it happens it is bad, the head is gonna skip off the surface of the disk like a pebble on a lake. It is going to be bad no matter what the data density is.

      So the difference between scratches and head crashes is miles apart, not just due to data density. In actuality the data density differences are insignificant compared to the other issues.

    After looking over all the pretty graphs, it seems the 74gb Western Digital Raptor spanks the other drives in everything but platter density. And to push this farther I saw nothing about its reliability published. The 500gb hd isn't using the new platter technology and the 160gb drive is crippled compared to the larger brethren because of its smaller cache. The only thing I got from this review was that if I needed a drive that performs I should buy a Raptor.

    Faster than what? All 7200 rpm drives have platters that spin at... 7200 rpm. Drives of this speed have been around for years and years. 10k and 15k rpm drives have been around for a while, too.

  9. Re:2 heads by el+americano · · Score: 4, Insightful

    Seems like a legit point to me. With 3 platters and 6 heads you could triple your data read rate by filling buffers simultaneously, whereas they haven't even doubled the data density. 25% did they say? On top of that, you don't gain speed for the increased number of tracks, only the increased track capacity. Call it 15% then? I think the power, noise, and speed and just hype, the story here is cost - mostly for Seagate's profit margin if it's a real competitive advantage, but I won't complain.

    So where's the 500GB version? Forget low power and noise, I'd rather have 1/2 Terabyte.

    Could anyone knowledgeable care to comment on how reliable this drive can be?

    I bought an external drive from Seagate and my experience with the drive was absolutely horrendous.
    It was so unreliable that I had to return the drive and paid a restocking fee.
    I thought it was just me, but these user reviews suggest otherwise.

      Could anyone knowledgeable care to comment on how reliable this drive can be?

      Unless a Seagate engineer that worked on this exact model comes forward and reveals a secret serious flaw, then no, NO ONE, not even other Seagate engineers, can tell you much about this drive's reliability.

      You'll hear plenty of anecdotes about reliability, and every company has a hard-core "anti-fan" base who will never buy that company's products again, after losing their porn collection back in 1996.


      Even within a drive family, you can't always extrapolate reliability data to other members of that family. One simple example I've seen (to my surprise) a lot here on Slashdot - A lot of people consider Maxtor as good for nothing but paperweights, because some of the earlier members of the DiamondMax line really really sucked. I, however, have half a dozen of the later DiamondMaxes in use today, some as old as five years, without a single failure, ever.


      So, buy either the cheapest or the largest (or the inflection in that curve, which IMO Maxtor usually solidly holds, thus my using their drives almost exclusively), and just make sure you have everything backed up. Because eventually, you will have a catastrophic HDD failure. And as much as it sucks to waste a few hours reinstalling your OS of choice, it sucks a LOT more if you don't have all your software, porn, data (but I repeat myself), music, and what-have-you readily available on a backup.


      Personally, I wouldn't buy a mere 160GB drive anyway, when you can get nearly twice that for $20 more. But this may have one nice side-effect, in that if Seagate pushes out a 4-platter 640GB drive (hey, no one will ever need more than 640GB, right?), the 400s should finally drop down to the golden $100-$150 range.

  12. Re:2 heads by Agripa · · Score: 4, Interesting

    It used to be possible to do what you describe however once track pitch became high enough they had to switch to using embedded servo data because head alignment was not longer consistent between platters. Not only is there platter to platter variation in track alignment but the tracks themselves are eccentric. The only way you can keep more then one head in alignment is to have more then one servo actuator.

    The last drive I had with dedicated servo tracks was a Micropolis 8760E 5.25 inch full height drive. Note that these types of drives actually can be low level formatted since the servo data is not involved.

Well, of course I had a burrito handy, and figured that once I did a nice fsck -- twice -- that I'd be reasonably okay, so I put the burrito in the front of the bezel, where the faceplate is supposed to go, bounced the workstation, and started the fsck. Then I went outside to smoke cigarettes. After smoking for a while, and socializing with people, the burrito was no longer frozen, but HOT! Voila, instant sysadmin lunch.

    Read about it here: http://www.mattscomputertrends.com/flashvsharddisk .html

    The gist of it is that right now your dollar buys about 130 times more hard disk space than flash memory. In almost every year, you can buy more space for your dollar than you could last year. This improvement for hard disks in the last two years was measured at 44% per annum. The annualised improvement for flash storage over the same period was measured at 118%. By simply extrapolating these figures into the future until the megs per dollar figure for flash beats that of hard disks gives the date of 2017 or in just 11 years time.
