SSD Cache for Archive backup extraction

we are using SP as a backup repository in order to archive backups from SPP to tape.

during archive backup. the data is compress at the vsnap, stored to colddatacache pool and then migrated to tape on the SP server. 

the restoration process is the same in reverse. Tape data are copied to colddatacache, data are then stored in the vsnap pool in a temporary location. while in temp location (that resides on vsnap pool disk) the backup is un-compress and send to the host for restoration.

during a time period were the vsnap disks had a huge load we had experience extremely slow un-compress restoration speeds.

it would be great if instead of using vsnap pool disks to be able to specify a filesystem with faster disks , like for example the disk designated for vsnap cache.

this will improve restoration speed from tape without having to deal with existing load (for example running backups) . tape backup is slow by design , lets improve as much as we can
