Seagate Announces 750GB Hard Drives
Hack Jandy writes "Seagate documents have leaked out the two 750GB 7200.10 Barracuda hard drives. The drives are the first desktop hard drives to use perpendicular recording, feature a 16MB cache and 7200RPM spindle."
Check out the Seagate Barracuda for more info.
We can finally Get Perpendicular!"
DYWYPI?
I suppose that why it has perpendicular recording.
We all know 16k of storage is more than enough for anyone.
Now I have to go to Costco and buy 3 250GB drives!
This issue is a bit more complicated than you think.
that will hold almost half of my porn!
I am not left-handed, either!
Each time the capacity of hard drives goes up a few gigs, I think back to the day in the mid 90's when I got my first "gig" hard drive for $500. Wow, it was the most incredible thing to be one of the first people in my neighborhood to have so much storage... I didn't think I'd ever run out of that much space. And today, the OS won't even fit into such a thing.
But let's put this huge capacity into perspective: Having once had to reverse engineer an obsolete 3.5" floppy drive to repair an obsolete piece of industrial machinery that was down (the customer couldn't afford to replace the whole machine because of a failed floppy drive, and the OS loads from floppy of all things), I learned that this contraption, which was on the market in the 80's, was really incredible, if you take a step back and think about it for a minute. Then, all it takes is a moment to realize that hard disk drives are several orders of magnitude more complex. First, the density of a floppy drive is nothing compared to that of a hard disk even from a decade ago, and secondly, the linear motion of the reading head on a floppy is controlled by a simple stepper motor, whereas the round motion of the reading heads on a hard drive is controlled by servo. I mean, just stop to think about it for a moment. All those gigs of MP3s, videos, and pr0n on someone's hard drive, and what an incredible piece of engineering behind them.
(from a co-worker)
750 (hard drive manufacturer GB) = 698.49 (real GB or GiB, depending on how anal you are).
As these sizes keep getting bigger the need to settle on one method of calculating GB, for both OSes and hard drive manufacturers, keeps getting painfully clearer.
Come on, there is no way that a 7,200RPM drive will have an average latency of 4.16ms, that's the pure physical latency of the platter! The transfer rate is similarly bogus, it's the burst transfer rate of the interface, not even the outer track transfer speed. Guess we have to wait for someone like storagereview to throw iometer at this beast and get some real info.

I'm sorry, but I really think you're mistaken. I and those in my field are caught in a seemingly unending storage excalation war. We provide 500 megabytes -- the users fill it up and demand more. We provide 50 gigabytes -- the users fill it up and demand more. We provide 500 gigabytes -- the users fill it up and demand more. Sure, they're wasting A LOT of space, and we could slow down the rate of growth by running scripts to delete MP3s or whatever every night, but that's a stopgap measure, and in the end is probably more expensive in terms of costly technician time than the cost of just slapping more drives in our Promise array. Currently we're backing up all of our servers to a 6.5 TB array via rsync -- and it's getting full. Give me a petabyte disk, please!

They're becoming IO-bound far faster than cache-bound. It takes literally hours to read an entire 500gb hard drive at this point. The cache, on the other hand, is staying roughly on par with the IO speed, which seems like a more natural combination.

It's getting to the point where you want to keep your OS and core applications in Flash memory and things that are less important on hard drives. I just bought a 512 MB usb key for $25. Scaling up, you could get a multi-GB flash drive for a couple hundred bucks.
Some companies have multi-tiered storage solutions (e.g. fast SCSI RAID, cheap EIDE RAID, optical, etc.). Some of those ideas may make their way into desktop devices. You'd boot off of flash memory nearly instantly (it would cache your OS and core applications), then you'd play your MP3s, surf the web, or whatever on your relatively slow hard drive.

Haven't you seen Blade Runner?
What will you PUT on it? But there comes a time after which we actually run out of relevant data to put on it.
Trust me, if your "relevant data" includes pornography, you will NEVER run out of data to put on it. Call that "Gabriel's Law" if you will. ^_^
Don't put advice in your sig.
Yes, it should considering that according to Wikipedia http://en.wikipedia.org/wiki/NTFS [wikipedia.org] states that the maximum volume size for an NTFS volume is 16EiB. One exibyte is 1,152,921,504,606,846,976 bytes, so 16 exibytes = 18,446,744,073,709,551,616 bytes. Since a 750GB hard drive should hold approximately 750,170,112,000 bytes, an NTFS volume should be able to handle 24,590,081 of those 750GB hard drives in a RAID array. Now assuming a RAID array can handle that many of these drives, and that this new 750GB hard drive merely takes the price spot of Seagate's current finest offering of a 500GB hard drive (priced on newegg as $295 each) http://www.newegg.com/Product/Product.asp?Item=N82 E16822148108 [newegg.com] rather than debuting at a higher price point, which it probably will, that many hard drives would cost about $6,147,520,250 before tax, and not including any of the massive discounts one might expect to recieve for such a massive purchase. On top of that, at a sales tax rate of 7.75%, the tax on those drives would cost you $476,432,819.38. So I don't know about you, but I doubt this is going to be a problem for either XP or Vista for a long, long time (assuming you use NTFS partitions).
the 750 GB hd is really only about 700 GB due to the manufacturers counting 1,000 instead of 1,024..
Anyway, lets look at how much space that really is, and how easy it is to fill up.
DVD Movies range from 4gb to 9gb depending on film length and extras, lets settle on an easy middle number, 7GB average.
That is around 100 DVD's you could store on your hard drive (My room mate owns over 150 DVDs, so while it might be a large number to some, it is not so large to others)
That is not including TV series, if someone were to store 1 season of the show 24 on their media center pc it would take 45GB of space.
Also concider that HD movies are going to be around 30GB each
Video games are getting increasingly large, Recent games like
The Godfather (4.5gb installed)
LOTR: Battle for Middle Earth II (5gb installed)
TES: Oblivion (6.3gb installed)
World of Warcraft (5.3gb installed)
Tomg Raider: Legends ( 7.3gb installed)
Games are only going to get larger too.
This is not even counting people who dabble with video editing or anything like that, work-wise that consumes monsterous ammounts of HD space..
Yes there's a limit to how big one movie will be.
:)
Actually, I don't think there is. A quick Googlin' turned up this site which informs us that uncompressed 1920x1080 video at 24 frames/second takes up space at around 400 GB/hour. So, one of these new 750GB drives maps to about one uncompressed high-definition movie, and it can't even be two hours in length (the site also tells us that this drive wouldn't even be capable of playing back such a movie - not enough bandwidth). Now, yes, we may not "need" to see uncompressed movies, but it could easily be argued that we don't "need" quality better than good old NTSC, either.
In 20 years, we'll be watching all our movies in digital form with no compression applied and/or the resolution/frame rate will be so high that we really won't be able to tell the difference between looking at the screen and looking out the window.

Good man.
I rarely criticize things I don't care about.
Pound the table all you want, but it simply isn't "just the way it is". Keep in mind that the http://www.essex1.com/people/speer/large.html predate computers by decades or centuries (depending on your precise definition of "computer"). According to the metric system:
The only way you could say that 1 kilobyte is 1,024 bytes is to make a special exception to the metric system's prefix rules, and the whole point of the metric system is to have a system of measurement without silly exceptions like that. If they had wanted a system where you had to memorize different rules for different units, they would have stuck with the imperial system.
So to sum up: some computer geeks thought it would be convenient for them to redefine the metric system to work using powers of two rather than powers of ten. This was fine as long as they were only interacting with other computer geeks. When computers spilled over into the world at large, however, this little shortcut conflicted with the way the terms were/are used by everyone else. Since the traditional (powers of ten) definition has both seniority and wider usage, it is now winning out, and rightly so.
I don't care if it's 90,000 hectares. That lake was not my doing.
When you buy your TB-iPod, it will come preloaded with the entire history of human musical creativity and you will buy unlock codes with iTunes.
When you write "musical creativity", does that mean it won't come loaded with country and hip hop?
