Does Anyone Do Recording With Each Camera Assigned To Its Own Drive(s)?

So let's say eight 1080p cameras each assigned to one of eight 2 TB drives. Talking real hard drives here, not SSD.

JBOD with 2 controllers.

Considering the way video is appended to files on a disk, I would think this would provide high performance. By using a dedicated drive per camera you would greatly eliminate the reseeking and rotational latency that naturally occurs as the streams are written/read concurrently.

Pros:

  1. Excellent write performance
  2. Excellent synchronized read performance
  3. Single drive failure affects only a single camera
  4. Cold single camera chronological archive could be created by hot swapping drive when full

Cons:

  1. Footprint may be larger, depending on retention period
  2. Cost may be more, depending on retention period
  3. Retention period constrained by drive topology

Are people doing this?

Why or why not?
