I was wondering too: 20GB/day FOR HOW LONG? For a year? Three? Five? Ten?
They don't say.

What they say is that it has a 3 year warranty. So I guess 365*3*20GB is
what they rate it for.

Or maybe this is an emerging industry convention of sort and this is the
first we (I) hear of it.

IIRC, your prior drive was also MLC? Which is to say, not the dreaded TLC

I don't know. And their site does not say either.

What is interesting is that the old disk had a 5 year warranty, the
replacement has 3 years only.

What I went through (copying one disk to the other) works, but there are
lots of steps to do after to get things working again (grub, hibernate,
...etc).

So, I will start with a fresh 14.04 install with all this working, then
copy my home directory, and perhaps save time that way. Also, I will have
the extra stuff that comes from Kubuntu that does not get installed when I
just install the meta package for kubuntu desktop. I used to have all that
before the original Toshiba hard disk died.

Also, I was used to going from one release to the other by doing:
do-release-upgrade. That took me from 8.04 to some intermediate non-LTS
release or two, then 10.04 to 12.04 and finally 14.04.

So, doing an install will tell me how things changed on 14.04 install-wise.

My own experience has been that such bloat (akonadi comes to mind)

I disabled it once (can't remember how), and since I copy my home directory
around, the configuration for it being disabled sticks with me. Never saw
akonadi turn itself back on.
