If you own 3 drives and one drive breaks, you still have got 2 drives.
If you have just one drive ... ;).

I'm using 5 small build in SSDs, one attached by SATA 2, since I only
have got 4 SATA 3 ports. I don't have got enough SSD space inside of my
computer. So, if I could turn back time, or if I were you, I would buy
one large, instead of 3 small drives, since now I anyway need to
replace the small drives one by another. Externals HHDs are good tom
archive seldom needed data and for backups, but not comfortable for
much needed data. I don't want to have a build-in HDD anymore, since
they are way to noisy for my taste.

Keep in mind that a large SSD has got more space for self-organisation
which might result in better performance and a longer life. OTOH more
ports might provide more bandwidth. If a drive is trimming, it might be
slower and not all drives trim at the same time.

Consider to steer a middle course, neither buy 3 SSDs nor 1 SSD,
consider to get 2 SSDs.

FWIW I try to avoid using a PCIe SSD as long as possible. Apart from
the mentioned issues, it might interact negatively with my real-time
audio interfaces, it needs a PCIe slot I might need for other hardware.
All my SSDs are from OCZ/Toshiba, since they are cheap, in my
experiences very good and the vendor provides Linux software. Note,
smartctl's data base does not contain all SSDs, if your SSD is missing
and the vendor doesn't offer Linux software, you don't get any
useful information out of your SSD. OCZ/Toshiba provides ocz-ssd-utility
to update firmware and to get correct smart data, unfortunately they
announced to discontinue SATA SSDs. OCZ/Toshiba will provide PCIe SSDs
only in the future (if they shouldn't already do so).
