For students normally 256 GB, any storage beyond 256 GB is meant for people who needs it for video editing, photo editing, and work. For example, for graphic designers they may need to download a software/program that will use up a lot of space on their computer to use for graphic design or illustrating. I recommend getting an external hard drive there’s a lot on the market, and you should consider Best Buy stores they should carry external hard drives. External hard drives helps you store music, files, photos, and videos so you won’t have to pay subscription for other cloud storage like Google drive, one drive, iCloud Drive, etc. I hope this helps.
The memory for computers varies if you need memory for downloading programs/softwares or apps on your computer keep in mind how much you’ll be using it for.
You know what I just remembered Apple literally combined it all the electronic they made and combined it a MacBook iPad iPhone combined it all together because they literally have the same features I'm not even going to lie
