I know, that's why mentioned internal/external, to be used in a tiny pc (nas server)2.5" internal hdd won't come in more than 1TB size for typical models, they are only available in higher capacity in enterprise/niche models which are rarely available & even then the max capacity is 5TB. Your only option for large capacity 2.5" internal hdd is to buy 2.5" portable external seagate usb drive & then disassemble it to take out the hdd inside & use it (max model size is 5TB which will have non standard thickness so won't fit inside laptop).
