I agree, but in this case, there "old drives" in both asps, of several sizes, but no "slow/large" drives. The 2nd asp was not a part of the original setup in '08.

It really depends on the disk controller, number of drives, drive types and speed, and size of drives.
4 2T SATA drives at 7200RPM will be slow compared to 8 320GB 15K RPM SAS drives. SCSI performance can really slow things down compared to SAS.
Most Archive ASP's I have seen have been of few large slow drives to hold lots of rarely used data. Would not put prod DB's there.

We want to balance our asps so asp 1 not so full, but don't want performance degraded.
If moved, user apps will be reading data from both asps. Asp 2 was orig set up years ago for old rarely used data.
