Talk:Disk controller

Disk controller of host adapter
An IDE or SCSI controller is not properly called a "disk controller". It is a host adapter. The disk controller is embedded in the drive. Mirror Vax 05:20, 4 May 2005 (UTC)
 * Agreed, since no one has commented on this page since 2005, I'll look to merge this into host adapter. Timbatron 07:39, 21 February 2007 (UTC)
 * See my comment over at Disk controller. Ralf-Peter 02:34, 12 March 2007 (UTC)
 * I'm confused, isn't this Disk Controller? Timbatron 15:11, 13 March 2007 (UTC)
 * Agreed, moreover "Hardware RAID" para should be split to separate RAID controller. This is equally often done inside a host system as inside a standalone disk array. Also a Hardware RAID information from RAID should IMHO be merged with proposed RAID controller. --Kubanczyk 06:58, 25 June 2007 (UTC)

Colloquial Term
I changed the word "mechless" to "not mechanical" as the word "mechless" does not exist in the dictionary, nor is it a commonly used word in this field. Jeremyburkhart (talk) 06:49, 23 November 2013 (UTC)

Need diagram and examples
The discussion of host adapter versus disk controller is too complicated, and seems to assume the reader already understands the issue being explained. A diagram laying out the flow of communication between disk and CPU would be nice, with labels for CPU, peripheral bus, host adapter and disk controller, along with a description of what function the host adapter and disk controller are performing. Examples with named host adapters and disk controllers would also help.

For myself, I understand the "positional" distinction, but I'm not sure I understand the functional distinction that is being made. I'm also not clear on whether the distinction applies in situations where the system board has a system bus. Does a system bus simplify this picture? — Preceding unsigned comment added by 70.247.162.60 (talk) 04:06, 18 November 2015 (UTC)
