back to article Square Kilometre Array reveals its 1.6TB-a-day storage and network rigs

Australia's first pass at the Square Kilometre Array – the Boolardy Engineering Test Array – is about to get commissioned into a fully-live system. The test array, known naturally enough as BETA, is part of the science-before-the-science: a proving ground for some of the new technologies being used for the SKA project, in …

    There we go then..tape isn't dead, official. For those who really really need it...

      Re: Tape

      When you say 'Tape' do you mean it's the size of a Cassette Tape (C-90) or a Betamax tape or VHS....larger, smaller, what?

        About 4x4x1", but these would be worked with in a pack that's a stack of 10 of them.

    aww, and after reading the headline, I was thinking, ok, 1.6TB/day, triple redundancy, thats like 8 4TB disks/week, no problem!

    tape? really? tape is for stuff you never want to have to read again. presumably all this science data will want to be read many times over.

      Tape is for stuff you want to read sequentially...

      And these files are sequential in nature.

      £50 for a 2TB HDD (consumer grade)

      £35 for a 2.5TB tape (LTO 6)

        Plus with tapes, you can load hundreds of them into a tape robot without issue.

          Not to mention, shipping tapes is a fair bit easier than hard disks. If you send a tape through the post, you can be pretty sure it'll arrive intact. If you send a hard drive, there's a fairly high chance that it'll get ruined by someone throwing the package across a warehouse.

          Plus with tapes you don't have 1000 electricity sucking disks spinning all year, or the intern whose job is permanently seeking out duff drives, or the engineering team trying to scale a RAID solution instead of just adding another shelf of tape to the robot library.

          Loading hundreds of tapes into the robot is never an issue. The issue always comes when the robot inexplicably fails to insert the tape into the drive properly.

            I know my supercomputer data lives on tape!!! In fact when the tool retrieves it from HPSS you can tell how far it has been buried.... ;-)

      Or stuff you want to read in 50years time

    It took me the first few sentences to realise you weren't talking about a RAID array 1km square. I really must drink some more coffee....

    currently working hard to fill the 10 PB ..

    News just in .. Intergalactic signal that filled the array, is in fact Jabba's secret porn stash of BBS (Big Beautiful Slugs).

      Kim Dotcom is a fan and follower of Jabba on Galacto-Tweet and has already loaded it to MEGA!

      Get your slugs in!

    Uh...check the math. 154 MB/sec is more like 6+ PB per 12 hours.

    Hard drive progress

    So...a 50PB hard drive (or solid state drive, whatever), is how many years away from being in your laptop? 10? 20?

      about as many years as holographic drives, sigh.
