It makes a lot of sense. Read the myth/fact part.

On a production RHEL5 server I have this:
$ du -sh /sbin /usr/sbin /bin /usr/bin /lib /usr/lib /lib64 /usr/lib64
38M /sbin
26M /usr/sbin
8.4M /bin
113M /usr/bin
130M /lib
440M /usr/lib
27M /lib64
339M /usr/lib64

$ du -sh /usr
2.2G /usr

I don't think you're going to find an SSD *smaller* than this, so why not just put everything on the same filesystem. Even on my Fedora desktop box (that I don't have access to right now), I don't think / and /usr are more than 15 GB together.

The split is from the era when hard drive sizes were measured in megabytes, not giga- or terabytes.
