Does The MacBook Air Have A SSD Or Flash Memory?
The MacBook Air uses Flash memory, which is essentially a solid-state drive (SSD) in a different form factor.
A SSD replaces a hard drive by combining Flash memory with a standard 1.8-inch or 2.5-inch hard drive enclosure. The new MacBook Air instead mounts Flash memory directly to the motherboard, which takes up much less space and allows the MacBook Air to have an incredibly thin form factor.
Unlike traditional hard drives, Flash memory/SSDs have no moving parts. They are quieter, less susceptible to damage, have lower access times, and faster boot times.
