[CentOS] SSD for Centos SWAP /tmp & /var/ partition

Has anyone actually used a SSD in a Centos setup?

My little experiment with a s/h WD drive for /tmp and SWAP 
partitions kicked the bucket on Wednesday, when the poor WD 
drive caught the click-of-death. It was a s/h drive 
to start with and lasted about 4 months. But that was 
without the /var/log/ partition being written to it, as I 
mounted that back onto /var/log from the original drive.

So I had to install another (WD) drive, and repartion it and 
rebuild my RPM package database, from the backed-up Packages 
file. That seems to be all OK now.

I'm wondering if it would be a good idea to use a new SSD 
for moving all the disk i/o to, that Linux likes to do so 
often. Plus putting SWAP onto a decent SSD should speed 
things up somewhat.

Here's a short video of a laptop fitted with a SSD drive 
booting macOS, compared to a similar laptop booting from 
the standard HDD.

The laptop with the SSD boots and loads some apps in 28 
seconds. The other one takes twice as long.


Kind Regards,
