Does anyone know how well the Breece-Hill Q1-15 (single drive, 15 cartridges) DLT tape stacker plays with the NetApp 630?

Does anyone know how well the smallest StorageTek DLT tape stacker plays with the NetApp 630?

I'm about the buy a new netapp and I'm trying to decide between these two tape drives for a locally attached tape drive.

Any comments, please?
