Letters to the Power Plant #34 — Big Drives

After I left the power plant and went to work for Dell on August 20, 2001, I wrote letters back to my friends at the plant letting them know how things were going.  This is the thirty fourth letter I wrote.  Keep in mind that at the time when I originally penned this letter I didn’t intend on it being posted online (Boy.  Times have changed).

05/17/2002 – Big Drives

Charles,

Do you remember the 20 MB hard drive I had on my first 8088 computer?  Then 200 MBs, Then 2 GBs (Gigabytes), Then 20 GB?  At home I have an 80 GB hard drive.  Well.  Anyway.  At Dell and Wal-Mart, and probably at OG&E, they are using drives that are Terabytes large.

Now.  To understand a Terabyte, it is 1000 Gigabytes.  A Megabyte is one million.  A Gigabyte is one Billion.  A Terabyte is one Trillion!!!  —  We have terabyte drives that store our databases.  We are moving over to a new database that will have a Petabyte (PB) of memory.

You can see where this is going.  1000 Terabytes!!!!  To put this into perspective.  That is 1,000,000 Gigabytes!!!!  No let’s go one step further, That is 1,000,000,000 (1 billion) Megabytes.  No, let’s call it what it is:  one Quadrillion bytes.  Or 1,000,000,000,000,000 bytes of information!!!!!!

Now I will say what I heard my dad say the first time he brought home a box of 10 low density 5 1/4 inch floppy disks, before there were hard drives.  “There are 360 thousand bytes (360 KB) on this disk!  Do you know how long it will take me to fill up just one of these?  I can put a whole book on just one of these disks, and I have 10 disks in this box!!!!  I will never use these up!!!”

Certainly, we will never use up a Pedabyte of space…….certainly not…….

I started writing this to just Charles Foster, but then I thought the rest of you might be interested in this exercise in Mathematics.

Your pal at Dell,

Kevin
