Time to write a petabyte of data?

[V8Driver]

Based on 20 minutes to write 25GB...
about 2 years?

1 petabyte / (25 gigabytes) =

40 000

*20 min. = 800000

/60= 13333.3333333 hrs

/24=

555 days

If the Super DVD is to be a viable format, it has to make a quantum leap in write speed.  However, it is based on 3-D memory and not optical storage.  3-D memory may be super fast at writes.  Without it in consumer hands, we'll never know.  And it's not even in enterprise hands yet as it's only just a recently announced technology.

 

However, I think your math is off.  If it takes 20 minutes to write 25 GB, 1 petabyte is 125 TB.  125 TB is 125,000 GB.  (Well, let's just conveniently ignore the 1024 factor.  )  So, 125,000 divided by 25 GB is 5,000 20 minute writes.  That's 100,000 minutes / 60 minutes in an hour / 24 hours in a day is 69.4 days.

1PB (petabyte) is equal to 1080TB  (terabyte) which is equal to 1166400GB (gigabyte)
After formating to the filesystem on Windows it becomes a round 1000TB or 1000000GB.

So doing the same math as above using these values, it would be like this:
1166400 / 25 = 46656 (discs to burn)

46656 * 20 = 933120 (minutes of burning discs)

933120 / 60 = 15552 (hours of burning discs)

15552 / 24 = 648 (days of burning discs)

All this would mean: 1 year and 283 days of burning discs.
