I've got an old RAID that I attached to a box. LSI card, and the RAID has

reasonable for it to be taking this long...?
not at all surprising, as that raid sounds like its built with older
slower drives.
I would discombobulate the raid, turn it into 12 discrete drives, and use
dd if=/dev/zero of=/dev/sdX bs=65536
on each drive, running these concurrently
unless that volume has data that requires military level destruction,
where upon the proper method is to run the drives through a grinder so
they are metal filings. the old DoD multipass erasure specification
is long obsolete and was never that great.
