My first was (and is still working) a Quantum 120MB SCSI for my Amiga.

Sideface:

 

<snip>  [re big RAID arrays]

 

I'm waiting for mine to rebuild, right now.

 

I estimate that it will take 3 days (8 x 8TB WD Reds, RAID 10)

 

WRONG!  It took me 7 days to completely reformat and rebuild the array. 

Big arrays do have some disadvantages.

All data is present and correct after the rebuild.
