this may be one of the more important responses... and also within the BIOS, or EFI/UEFI one may need to set the SATA controller mode to AHCI and then also mark each disk as SSD within the bios. My Asrock board on home pc is like this, can't remember if there was a similiar thing on server boards (supermicro) I have at work but i don't use SSD at work.

@ron - What do you mean by setting the SATA controller mode to AHCI? How does it affect the ability to accurately report if the device is a SSD or not?

look up AHCI vs IDE, wording from first web search: IDE is considered adequate for the average computer user, and is the most compatible with other technology, particularly older devices. However, it lacks support for new technologies...AHCI provides a standard system that designers and developers can use to configure, detect, or program SATA/AHCI adapters.*

that is a basic settings in the BIOS, somewhere under Storage, the choices are IDE, AHCI, and also depending on make/model/year of motherboard can also offer RAID. SSD's came out long after IDE basically went obsolete and the standard became AHCI, For example installing Windows95 on a computer today it would not recognize any hardware... being in IDE mode certainly would not help communication with a SSD not so much accuracy but simply being able to communicate with a SATA controller which is based on AHCI protocols.
