General informations

The Linux kernel configuration item CONFIG_BLK_DEV_IDE_TCQ:

Help text

Support for tagged command queueing on ATA disk drives. This enables the IDE layer to have multiple in-flight requests on hardware that supports it. For now this includes the IBM Deskstar series drives, such as the 22GXP, 75GXP, 40GV, 60GXP, and 120GXP (ie any Deskstar made in the last couple of years), and at least some of the Western Digital drives in the Expert series (by nature of really being IBM drives).

If you have such a drive, say Y here.
