I'm considering turning on Tagged Command Queuing in my ATA system. My
disks are all Hitachi 7K250 (two HDS722512VLAT80 and one
HDS722516VLAT80) which according to Hitachi support this feature (queue
depth = 32).
However, I read in
that there may be problems doing this and not really improving performance.
Is that recommendation still valid or should I go for it?
