Sony tape smashes storage record
The iPod let you put your entire music collection in your pocket. Now Sony has something that could let you put the world’s music collection in your pocket: a cassette tape that holds 185 terabytes of data. It’s 3,700 times more storage than a Blu-ray disc.
To put that in perspective, the tape can hold about 60 million songs — far more than anyone could listen to in their lifetime (that would be about 17 million, assuming continuous listening for 100 years, even while sleeping, and 3 minutes per song).
The recording density of the 185TB tape is about 74 times the capacity of current tapes, Sony claims.
It’s in big-data applications that such a high-density tape is really needed. Facebook, for example, stores more than 300 petabytes of data from its users (a petabyte is 1,000 terabytes), and that data has to go somewhere. Tapes are used for most high-capacity data archiving for the simple reason that the storage density rivals anything else. [via Mashable]
