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.

I should add, that you can run a hybrid setup where you run your system on the SSD and put your home directory on an spinning drive.   That's actually how I have most of my systems setup as I use a HUGE amount of space.  That way all the stuff that needs to be fast is and the stuff that just needs to be stored is on the cheaper spinning disks.

If you want to do that, you can same a lot of money and just get a 240gig SSD, which is more than enough for your system files, and spend the different in cost for a couple of terabytes of spinning storage.

If you want to get really fancy, you could partition part of your SSD off and use it as a cache for your spinning drive and kinda have you cake and eat it too.

Contemplating ordering an SSD as at least the boot and main drive for my PC.

Is that even a good idea?  Are /var, logfiles, and all the other stuff that constantly gets written to disk, still a Really Bad Idea for solid-state memory with its limited write cycle times?

Or is that no longer an issue?

And does anyone really trust SSD to maintain actual documents, family photos, and such over long periods of time?
