Help With Replacement SSD Drive

I currently have a a Samsung MZVLW128HEGR-00H1 (128gb) drive and I want to replace it with a WD SSD. I see WD makes Red, Blue replacement drives. I notice the Red says NAS. Is there any reason that can not be used for a desktop? If either the Red or Blue can not be used, what replacement is suggested, 1TB, 3.5" Sata. I believe the current drive is sata II.

Thank you
