I've just finished coding a new balancing plugin for StableBit DrivePool, it's called the SSD Optimizer. This was actually a feature request, so here you go.
I know that a lot of people use the Archive Optimizer plugin with SSD drives and I would like this plugin to replace the Archive Optimizer for that kind of balancing scenario.
The idea behind the SSD Optimizer (as it was with the Archive Optimizer) is that if you have one or more SSDs in your pool, they can serve as "landing zones"
Specifically, the reason for the multiple disk requirement is the Real Time Duplication feature. This feature specifically writes out all copies of the files, to the disks in the pool in parallel.
The reason this is a big feature is that when a program opens a file, it locks it. That means it can't be moved, copied or otherwise altered while the file is open. This includes data on the pool, and definitely affects the ability of our software to duplicate the data.
And why does this matter
