What comes after the Terabyte?

I’ve a question: what comes after the Terabyte?

8 bits = 1 Byte

What comes after the Byte ?
1024 Bytes = 1 Kilobyte

What comes after the kilobyte ?
1024 Kilobytes = 1 Megabyte

What comes after the Megabyte ?
1024 Megabytes = 1 Gigabyte

What comes after the Gigabytes ?
1024 Gigabytes = 1 Terabyte

What comes after the Terabytes?
1024 Terabytes = 1 Petabyte

What comes after the Petabytes ?
1024 Petabytes = 1 Exabyte

What comes after the Exabyte ?
1024 Exabyte = 1 zettabyte

What comes after the zettabyte ?
1024 zettabyte = 1 Yottabyte


  1. Well here we are, almost to 2012! I notice not many people have mentioned Moore’s law, that computing speed will increase 100% with respect to materials every 18 months. It’s funny; last night I was doing the math. If correct, that means by 2026 (15 years away) we will be dealing with a standard “petabyte:” hard drive. So it may be awhile before we, the consumers, have affordable yottabyte PC’s! But hell, pc’s get faster so we can condense better quality media as well. We have always downloaded MP3s, but only recently could you download your entire music catalog in FLAC without breaking the bank. Same with movies…but my question is this:
    Does it get any better than FLAC? That’s source quality, right?
    So what about movies? When the picture has become as clear as human eyes can distinguish?

    My question is, how much speed and storage will one person ever need? I think a petabyte is more than enough for one person to handle every media item you may incur in your lifetime!

  2. There is no practical reason to produce a Yottahert processor! The future isn’t in raw performance from a single processor, it’s from PARALELL processing!

    The greater frequency you try to sap from a semiconductor, the more heat you produce in the process! This was realized long before the 3GHz barrier was reached for consumer microcomputers!

    Instead, the trick is to cram more and more independant and interoperative cores on a single chip. There are already 12 and 24 core CPUs on the market (in the server market anyway), with 6 and 8 core CPUs growing in popularity amongst the more hardcore consumers (gamers, mostly).

    As Kray once put it: “What would you rather use to plough a field – 1 strong oxen or 1024 chickens?”
