A Linux server using an SSD shows elevated read/write wait times. Which change reduces disk operation delays most effectively?
Enable the discard mount option
Switch the disk scheduler to noop
Increase the RAID controller’s stripe cache
Create an additional swap partition
The noop scheduler merges sequential requests without reordering, aligning with how SSD controllers internally manage queues. The discard mount option triggers block reclamation but does not lower request latency. Increasing RAID cache targets spinning disks and is irrelevant for a single SSD. Adding swap shifts memory pressure to storage and can increase wait times.
