Homelab Brief - Linux I/O Schedulers for HDD, SSD, and NVMe · Big Iron Radio

  Welcome to the Homelab Brief from Big Iron.

  Today, picking the right Linux, a slash O scheduler for your drives.
• 0:11
  Quick note, this is an AI voice drawn from a Big Iron guide.

  Links below.

  Linux in 2026 has four real A slash O schedulers.
• 0:22
  None, MQ Deadline, Kyber, and BFQ.
• 0:25
  The old single Q1's CFQ and Noop are gone,
• 0:28
  so any advice that still mentions them is stale.
• 0:32
  The whole game is matching the scheduler to the media.
• 0:36
  For NVMe, use none.
• 0:39
  The drive's own controller manages its queues better than the kernel can,
• 0:43
  so the fastest thing the kernel can do is get out of the way.
• 0:47
  Treat that one as mandatory.
• 0:49
  For spinning disks in SATA or SAS SSDs, MQ Deadline.
• 0:54
  It's read-prioritized with a write deadline,
• 0:57
  so nothing starves the safe, boring default that just works.
• 1:02
  Then the two specialists.
• 1:04
  BFQ is tuned for desktop interactive feel-lovely on a laptop,
• 1:08
  but its CPU overhead is catastrophic on a busy server,
• 1:12
  so keep it off your lab boxes.
• 1:15
  And Kyber is a niche pick only
• 1:16
  when you're chasing specific P99 latency targets.
• 1:20
  Most people never need either.
• 1:22
  To make your choice stick, drop a UDEV rule in etc. slash UDEV slash rules,
• 1:28
  D slash 60IA schedulers, rules,
• 1:31
  and reload with UDEV Atom, otherwise it resets on reboot.
• 1:35
  And if you run ZFS, don't even think about it.
• 1:38
  ZFS auto-sets none on its pool members already.
• 1:42
  The full rule templates in the guide.
• 1:43
  That's your brief.
