Best way to save redis keys

I use Redis to store some information and detect changes in this information over time (for example, I think users and locations). What is the value of using a longer or shorter name? Using a longer key is clearer, but is there any greater cost for memory or performance when using a longer key?

Here are some examples:

SET L:123456 "<name> <latitude> <longitude> ..."
HSET U:987654321 loc 123456 time <epoch>

or

SET loc:{123456} "<name> <latitude> <longitude> ..."
HSET user:{U987654321} loc 123456 time <epoch>
