whats more optimized?

say i have this function
foo:bar
$say $(a)

what would be more optimized?
1
data modify storage foo:bar args set value {a:"a", b:"b", c:"c", d:"d", e:"e"}
function foo:bar with storage foo:bar args

2
data modify storage foo:bar args set value {a:"a"}
function foo:bar with storage foo:bar args

would this affect the performance at all ?
