Disable NCQ

Disabling NCQ (Native Command Queuing) can in some circumstances improve performance

<syntaxhighlight lang="bash">

  1. To check if ncq is already off, its' likely not if you haven't already turned it off

cat /sys/block/sdX/device/queue_depth

  1. it will return 32 if it's on
  2. To turn it off:

echo 1 > /sys/block/sdk/device/queue_depth

</syntaxhiglight>
