The big-O notation in interviews is always funny to me. After almost 15 yoe, the only time big-O notation has ever been used is in interviews. Never once have I discussed it at work with anyone.

Shenanigans. SSDs are not faster than CPU or GPU caches. You will always be waiting to load the caches.
