Most consumer drives only have 7% which is grossly inadequate in these kinds of workloads.

I don’t see this mentioned anywhere. So should i set aside 12% of the SSD capacity in order to keep performance top notch all the time, or does btier handle trimming?

It looks like btier is a very solid caching product – significantly faster than flashcache or bcache. But it does not seem to be getting as much publicity, why is this?

What does it take to add btier to Centos? For example, patch the kernal followed by a full kernal re-compile, or something more modest.

How difficult is it to setup compared to Flashcache and Bcache?

Thanks, Colin
