A hard drive contains metal rotating platters that store data magnetically. The conventional hard drive has been the main form of mass storage in computers for many years. The SSDs that Apple offers for the MacBook Pro tend to be expensive and perform poorly compared to the best SSD upgrades available from third-party manufacturers, so your best bet is to purchase a MacBook Pro with a conventional hard drive and upgrade it with an SSD yourself. However, the MacBook Pro still has an advantage its hard drive is the standard 2.5-inch size, which means that you can remove and replace it with the SSD of your choice. In fact, the MacBook Air feels like a faster machine in some applications because it includes a solid-state drive (SSD) by default.
However, because the Sandy Bridge MacBook Pros include conventional hard drives by default, they aren’t quite as quick as they could be. Apple has released an incredibly fast line of notebooks with the new Sandy Bridge MacBook Pro series.
