starting to think about a new laptop that will, among other things,
do lots of OE/YP builds, and i'll start with this as the basis for a
few questions about hard drives:

while an SSD would be delightful, i'm concerned about how doing
frequent 40-50G builds would wear out an SSD. so i was considering
looking for something with a fast regular HD for the actual build
directories, but room to put in an M.2 NVMe that would hold fairly
static content, like the OS itself, all the layers, a local source
mirror and so on.

am i overthinking this? anyone have a laptop setup that is smokin'
fast (yeah, 8 core AMD ryzen :-),
When using a laptop with only 16 GB RAM to build with 8 or 16 threads,
on what drive will the heavily used large swap partition be?

gcc loves to use > 2 GB RAM for non-trivial C++ code,
with 16 threads I'd recommend 64 GB RAM.

and a dual drive layout that seems
to work well with lots and lots of OE builds?
Ask for the specs of the SSD and do the math.

E.g. 150 TBW / 50 GB/build = 3000 builds

If you are building from scratch so often that the resulting number
is a worry, I'd rather buy 128 GB RAM and use a tmpfs instead of
creating a spinning rust bottleneck.
