New computer hard drives run at 1 tb!
|
Isn't a terabyte a 1000 gigs? I didn't know this was a big deal. Yesterday at BB I purchased an external USB hardrive (laptop user) with 250gig for $99, and they had external terabyte drives for $449 with IEEE 1394 and USB.
I saved a small forest! |
1tb hdd will rock. cant wait for 2nd generation and the price to come down.
|
Yeah, I've been seeing 1TB external drives for quite some time now, AT LEAST a year, maybe two.
|
Terabyte drives might be old news in professional multimedia systems but I bet no one's running a yottabyte drive. Now that would be something.

Pete beat me to it, but yes, all those drives are made up of two hard drives in one enclosure.

One question though, apart from being cheaper to manufacture, what would be the benefit of a single drive over a multiple one? |
You can put two 1tb drives into one case to make a 2 tb drive. It's also more efficient.

In short does size matter? |

I can say I have a tendency to want to have 4 250GB external drives around and swap them as I need them. If any one of them dies I still have 75% of my files. If I have one great big TB drive and it fails.....I have 0% of my files. At this point in time I can easily handle HD projects and not exceed 250GB so I am OK. |

Also note that the next increment after the terrabyte drive (or drive set) is the petabyte drive. These are used to store petafiles (sorry, I just had to). |

Just told my wife your petafile joke, she looked at me like I was mad:) |

Are you sure this is just 2 500GB discs? Because they do have a version of this that is 2 discs that is 2TB, and this has been out for quite some time. |
Matthew, that LaCie unit is indeed 2x500GB drives. Read the reviews at the Apple Store or over at Newegg and other places. Or just the specs at LaCie's web site. Their 2TB Bigger Disk Extreme is 4x500GB drives in one enclosure.
Hitachi is still the only one shipping 1TB hard drives. They were announced as available back in December, but supply has been extremely limited. PC vendors like Dell haven't been able to get the quantities to actually offer them in production systems until now. Seagate also has 1TB drives ready to go and should be shipping them within the next few weeks. I know Maxtor has announced them as well, but don't know when we can expect them. I have yet to see any real-world benchmarks and reports of the 1TB drives. Either Anandtech or Tom's had a brief review of the Hitachi unit within the last 60 days, but it was rather brief. Price on these drives is MSRP $399. Look for street price from most online vendors to be ~$370 and commonly available here in about another 2~4 weeks. |

I have no idea which parts and factories apply to the two brands though. It's probably pretty fungible by now. |
Larger drives are faster because they have a higher density of data per drive platter. For a 2TB mirror, you are better off getting two 1TB drives than four 500GB drives, unless you can run RAID0+1.

LaCie, for me, was a mixed bag, but I think that's common with most drives. I love Fantom and G-Tech, though we had three G-Drives go down at the same time. Same with LaCie.
But those may have been isolated. Because new G-Drives and both older and newer LaCies have done well for me, and also where I work. Drives will eventually fail, esp. if they're bumped to the floor, which happened to our LaCie. Heath |
I think the title of this thread should be something else other than what it applies. It's a tad misleading :)

It was in reference to drives that "run" at 1TB. When I first saw the title of this thread, it read as if there's new drives that have a 1TB per sec transfer rate.
run doth not equal capacity :D Bill |

If you dig around for the report from Google on drive failure (they have a LOT of drives) they found no correlation between drive temperature and failure. Nor did they find any one that was better or worse than others. What they did find was the typical bathtub curve, if it doesn't fail early in it's life due to a manufacturing defect, it'll almost certainly last quite a long time until it wears out. This is pretty typical of most thing, particularly electromechanical devices and kind of makes those MTBF figures a bit misleading.
NAS devices are very cheap these days, we have just bought the Thecus 5200 with 5x400G Samsung drives in RAID 5 and so far liking it a lot. We could have fitted 5 x 1TB drives but the $/GB was best on the 400GB drives. |

re: GOogle report:
http://labs.google.com/papers/disk_failures.html re: 1TB drives, Hitachi has announced 960GB usable disk space (though marketed as 1TB) single disk drive 7200rpm should be available for purchase around august, september. Seagate's working on squeezing more GB per plate so that they can achieve a "true 1TB" usable space (maybe market it as 1.1TB?) that's the rumour i think. it will most likely be more like 990GB usable space or somn stupid like that. should be available for purchase december 07 into spring of 08 for cheaper prices. all sata BTW as sas will take probably 5-10 years to reach such a large disk size @10,000rpm or 15,000rpm. initially, price of the hitachi is $600ish MSRP, seagates is comparable, but by late '07 hitachi should inch closer to $500 or close to 400 with rebates, etc. seagates will debut late 07 and be close to 400-500 by summer of 08 or maybe winter. by then, 1TB drives will be flooding the market =D. even if you have a 4port raid0 (not that you should do it, but technicall you could) you can get 3.7ish TB of usable space. if you're crazy and have 8port or 16, 24ports you can have close to just as many TB's in raid6 even! i just can't imagine the rebuild time if 1 disk dies. |
