Great Move I think
wow! So Facebook/Twitter will no longer need to secretly compress posted pictures to 640x480.
330TB is all very well but it's pie in the sky...
.. because, currently, tape cartridges for Joe MediaHoarder top out at a mere 6TB, the drives are very expensive and the cartridges are not cheap.Quote:
Currently magnetic storage on spinning disks is much less space efficient with a 3.5-inch HDD (also about a third of a litre volume) which top out at 12TB.

LTO-6 ... 2.5TB ... £1300-£1700 ... https://www.scan.co.uk/search?q=lto-6
Cartridge ... £25 ... https://www.scan.co.uk/search?q=tape+cartridge+lto-6
LTO-7 ... 6.0TB ... £2700-£3500 ... https://www.scan.co.uk/search?q=lto-7
Cartridge ... £90 ... http://www.misco.co.uk/product/2578164/HPE-LTO-7-Data-Backup-Tape-Cartridge
Break-even for LTO-6 is about 90TB and for LTO-7 it's about 280TB (versus 8TB harddisks at £200).
Nevermind 330TB being pie in the sky seems storage is yet another field where we hear wild tales about scientific breakthroughs allowing 10 billion petabytes to be stored on a single molecule and yet here we are still with good old clunky magnetic tapes.
And then, there's those access times lol.Quote:

Because magnetic tapes are robust, with arcival times > 20 years, and cheap.Quote:
