How much database space would you need to hold user information fo开发者_如何学Pythonr 100,000 users?

That depends heavily upon what information you hold.

If it's a username, an MD5 of a password, and a few short fields, I'd say:

6 + 32 + 5 x 200 = 1,038 bytes ~ 1,040 bytes

So for 100,000 records, I'd say that:

1,040 x 100,000 = 104,000,000 ~ 100,000,000 bytes

Which is around 100 mb.

Not that much.

100,000 times the amount of database space you would need for 1 user.
