Hi everyone,

I recently worked on a computer that had a single TB drive, It was bought from a store and no hardware had ever been changed.
While I was working on it I noticed it to be quite slow given the specs it had (no virus's) while rebooting I went in to the bios to make sure things were set up right.
I found that the Hard drive was set in raid, to my knowledge raid is to be set only when having more than one disk.
Later I found that the drive was failing and the computer was given a new drive, so the computer is now fine, but I would like to know if setting raid on a single drive be harmful in any way and also why would the original drive ever have been set in raid?

Is the BIOS a UEFI type?

Possible it was set for AHCI booting wich often includes the RAID option.

If your drive is an SSD you might lose the ability to use the Trim capabilities of the drive and getting SMART parameters out of it, but I don't think you will do any 'damage' to your system.
