After that I don't bother... too big... :-)
Disk-maker Seagate claims to have become the first company to ship three zettabytes' worth of data storage devices. A zettabyte is a thousand exabytes, and an exabyte is a thousand petabytes. The latter quantity is far from fanciful these days. Seagate already offers an 18TB Exos drive, they'd only have to sell 56 to hit a …
So far there is no official prefix for 10^27. If they follow the current pattern they will start with nona, decide that Nm is too ambiguous (nonametre or Newton metre) and that nm is already nanometre so go for xona (X) for 10^27 and xono (x) for 10^-27. They could just as easily go Greek and select xenna and xenno. I hope they spilt the difference so we can have Xena and xeno.
Actually ... come to think of it, watch this space ;-)
I was thinking of that/and also did think of suggesting it to you on my post - I think you have mentioned in the past contributions to the Linux kernel or something like that, so thought you will be up for that.
