I strongly encourage you to run "smartctl -l scterc /dev/sdX" for each

echo 180 >/sys/block/sdX/device/timeout
If the report says read or write ERC is disabled, run "smartctl -l
scterc,70,70 /dev/sdX" to set it to 7.0 seconds.
You then set up a boot-time script to do these adjustments at every
restart.
Sounds like a very bad idea if your drive is part of a RAID array.
Either of these - the scterc if you can, the device timeout if you can't
- are an excellent idea if you are using a desktop drive as part of a md
RAID array. Why do you think otherwise?
Cheers,
