a yotta bytes

[SomeOldGuy]

There was a posting on / . regarding the amount of disk storage being shipped by the HDD manufacturers.

"David Roberson, general manager of Hewlett-Packard's StorageWorks division, predicts that by 2013 the storage industry will be shipping a yottabyte (a billion gigabytes) of storage capacity annually. Roberson made the comment in conjunction with HP introducing a new rack system that clusters together four blade servers and three storage arrays with 820TB of capacity. Many vendors are moving toward this kind of platform, including IBM, with its recent acquisition of Israeli startup XIV, according to Enterprise Strategy Group analyst Mark Peters."

I always wondered where they come up with these, and now I find there apparently is an "approved" list of geek-math-terms to describe them.

Here is the list (from / .) :

yocto- y 10^-24
zepto- z 10^-21
atto- a 10^-18
femto- f 10^-15
pico- p 10^-12
nano- n 10^-9
micro- m 10^-6
milli- m 10^-3
centi- c 10^-2
deci- d 10^-1
(none) -- --
deka- D 10^1
hecto- H 10^2
kilo- K 10^3
mega- M 10^6
giga- G 10^9
tera- T 10^12
peta- P 10^15
exa- E 10^18
zetta- Z 10^21
yotta- Y 10^24
