I would think it would be pretty soon but I can contact areca to find
out. What model of controller are you using? I have the firmware for the
ARC-1222 and ARC-1880.
I pushed out the new firmware to around 600 machines running areca
controllers with no problems so far. After all of our 1000+ servers I
found that around 60 drives in various machines had drives that were
actually smart failing (mainly re-allocated sectors and end-to-end) and
the controller had not kicked the drive yet =(. I am later going to go
through and start replacing drives with >100 re-allocated sectors as well.
