HDD

Solid-state drives are all the rage lately, thanks to their high transfer speeds and ultrafast access times, but most people still use cheap, spacious mechanical hard drives. Unfortunately, mechanical hard drives also constitute one of the most significant performance bottlenecks in modern computer systems. Even when paired with the fastest processors and lots of memory, a slow hard drive will drag down the a system's overall performance and responsiveness, which is why upgrading to an SSD usually yields such significant performance gains.
