Internal hard drives are mounted in the computer or an external storage chassis. These are mechanical hard drives with spinning discs and they are available in sizes up to 3.5 inches. Select in the filter how fast the hard disk should be, the connection method, the amount of cache and access time. It is also possible to filter on only hybrid disks that combine the mechanical hard disk with built-in storage memory for extra performance. Products in this category are also called Internal Hard Disks.
