IBM Prepares 100-Terabyte Tape Drives

It's a well-known fact that we're living in an era of data explosion, and that it's not about to stop. So it's not really surprising that IBM researchers are eyeing 100T-byte tape drive. Yes, you read correctly. They want to increase the capacity storage of their largest units by 250 times, from 400 GB to 100 TB. In order to achieve this goal, they're borrowing "nanopatterning" techniques derived from the microprocessor division. Today, the size of a tape track is about 10 microns. They want to reduce it to 0.5 micron -- or 500 nanometers -- in about five years. IBM doesn't really say when a 100-Terabyte tape drive will be available. But more importantly, the company doesn't say a word about future data transfer rates, which today reach a 80 MB/s. Read this overview for more comments about this problem of data transfer rates.

Sweet storage... you can never have enough. Apart from the plain space, developers also have to keep speed in mind. Using the transfer rate mentioned in the article, it would take 364 hours (a bit over 15 days) to fill the tape. But then, I couldn't download 100TB in two weeks anyway...
