The SSD Optimizer plugin - only lets you designate the whole SSD drive. Now that larger SSD's are more readily and cheaply available - i have a 2 TB drive - but split into two partitions. The idea is to use a smaller partition (300GB) for caching, and the remainder (1.6TB) for normal storage.
However - i cannot configure this, as the optimizer see's and tags the whole disk as the cache drive - not just the partition(s). The only workaround so far - is to use file placement rules to place certain folders on the larger SSD partition.
Could this be addressed in an update?
