SSDs versus spinning-rust drives

[Stephen Partington]

I do lvmcache on my servers all the time. And when provisioning I can build
in extra space for wear leveling. I actually did a presentation on setting
up lvmcache and can even include the ppt from that.


I have also used it on a desktop and it actually saw a benefit as well.
Although I no longer have a desktop and my replacement laptop is 100% SSD.
