External Drive Between MAC and PC?

My daughter has a MAC laptop. Her office laptop is an HP PC. She often needs to transfer videos between both devices. I want to buy her an HDD that will allow this transfer and storage. Is it possible? Thank you

format it exFAT File System and it can be used with a PC and Mac

Well, most external hard drives are designed to work for Windows computers. Windows was mainly optimized for NTFS (New Technology file system) format, on the other hand, APFS was created for the Mac OS. NTFS is not compatible with Mac and similarly, APFS does not get along with Windows. So if you’re trying to connect an external hard drive to a Mac, you might have to format the drive before you can use it.
