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.

Matthew Overstreet April 10th, 2007 08:56 AM

Yeah, I've been seeing 1TB external drives for quite some time now, AT LEAST a year, maybe two.

Liam Hall April 10th, 2007 09:15 AM

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.

That's because those devices either use 2 x 500GB or 4 x250GB hard drives. Single HDD's of 1TB were anticipated to be released this spring...and here they come!

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

I suspected that might be the case.

One question though, apart from being cheaper to manufacture, what would be the benefit of a single drive over a multiple one?

Heath McKnight April 10th, 2007 10:11 AM

You can put two 1tb drives into one case to make a 2 tb drive. It's also more efficient.

What do you think of doubling storage capacity over 500 GB disks or even quadrupling over 250 GB disks? In a very compact (2 disk) enclosure you can now get 2 TB. Just be aware to only use eSATA and not USB or fire wire to get the full benefit.

Obviously, they'll be more storage. What I mean is will a 1TB drive be faster and more durable than 2 500GB drives or 4 250GB drives? Will it be quieter and less prone to fail?

In short does size matter?

I don't know if it would be more prone to fail or not. Keep in mind that if you have 2 drives in an enclosure, wouldn't you say there is 2x greater chance that one will fail? If configured in a RAID 0 (Which is most likely) you lose everything anyway. So......I don't know.

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.

Absolutely. If the probability that one drive in a pair will fail is p the probability that neither will fail is (1-p)*(1-p) = 1 -2p + p*p. Thus the probability that at least one drive will fail is 2p - p*p or not quite double. That's why RAID sets (in some configurations) use redundancy. The probaility of a failure is higher.

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).

Nice math, but it doesn't tell us diddly squat about whether or not using one new drive as opposed to two older ones is a better option. The new drives incorporate a new manufacturing technique and I'll bet they're just a little bit flaky.

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.
