I just converted my boot drive from Legacy to UEFI so that I can get faster boot and shutdown times. It worked out pretty well, but now I am wondering about my other drives. I have a 1TBM.2 ssd as my boot drive. I have a 1TB SATA SSD for my game drive. I have a 1TB HDD for music, photos, and other files and a 250 gb HDD for other random stuff. As you can tell every time I do a drive upgrade I just keep my old drives and repurpose them. So I am wondering about my old drives, should I convert them to UEFI also? They seem to still work fine as is, but I am wondering if there is any benefit to doing so.
