But the spellcasters who do it that way aren’t very powerful: One spellcaster early on in the books considers himself the Big Cheese of wizards because he can hold a whole FIVE spells in his memory at once.

But they were some really kick ass spells, and wizards could do things like detecting magic without a spell.
