Depends how much you are storing.

If it is 1TB then yes, a $1000 drive and a $25 tape makes it $1025/TB

If you are backing up 10TB it becomes 1250 / 10 = $125/TB
For 100TB 3500 / 100 = $35/TB
For 1000TB (1PB*) 26,000 / 1,000 = $26/TB

1PB* may seem excessive, but if you were backing up a commercial server every week you could meet that pretty quickly. Of course then you would probably invest in a few more drives, increasing the $/TB, on the other hand you would put the tapes in a rotation.

Edit:

*Assuming the drive manufacutrer's definition of 1 PB = 1,000 TB, rather than 1PB = 1024TB

Didn't they remove support for pretty much everything useful in Final Cut Pro X?

Also, the fact that random access times can often be measured in minutes doesn't bode well for loading games (or much of anything besides backups) off of it.

My thoughts exactly.

And re. the price per TB, heck, you can get DVD-R's in bulk that amount to about $0.03/GB. Price per GB or TB of media alone is an insignificant metric.

Yes but DVD's degrade at a much faster rate. Tapes last much longer, so you don't have to re image the backed up data nearly as often. DVD's are a terrible way to store long term data.

Well, duh, they're made for servers. My point was, several people in this thread were talking about putting them in their computers for extra storage for just $25/TB, not taking into account the cost of the drive to use the tapes. Very few people here probably store the 25TB+ worth of data on their home computer necessary to make a $1,000 tape drive worth the purchase, and fewer still would rather use a tape drive for the data instead of a regular HDD, due to access times.

Same here. We also sell many tape libraries to large companies.

I used to build the large (10") reel to reel storage systems for StorageTek (then SUN, now Oracle).

I know--I didn't mean to imply that people should be relying on them, only that price per GB or TB is pretty meaningless. smile.gif

Why do you think DVD's degrade? As long as you store them properly you should not have to worry about them degrading.

This is why tape is only good for archiving. At work i have pulled archive of files off of tape and it was a pain in the ass. Sequential pulling the whole archive up isnt so bad but searching for a file forget it. Thats why we backup Synchronous to SANs and archive from our backup SAN to tape, based on our archiving policy.

Last quarter at school (ITT) we went on a field trip to a local hospital's old data center. They still had a couple of tape drives as their last-resort backup, so I kinda figured this tech hasn't died out completely. Actually I'm really glad to see it coming back considering how cheap the media is.
