[0048]
[0049] Among them, the 2.5-inch SSD disk (2.5-inch solid state drive) has a physical size of 2.5 inches wide and is usually between 7mm and 9.5mm thick. This size makes it compatible with the 3.5-inch hard drive slots of most laptops and some desktops (by using an adapter). The 2.5-inch SSD disk mainly uses the SATA interface.
[0050] 3.5-inch HDD disk (3.5-inch mechanical hard disk), the physical size of a 3.5-inch HDD disk is usually 146.99 mm (length) × 101.6 mm (width) × 25.4 mm (height), which enables it to fit into the internal space of most desktop computer cases. 3.5-inch HDD disks mainly use SATA interface, which provides good data transfer rate and wide compatibility.
[0051] Currently, the maximum rate supported by the SATA3.0 signal protocol is 6Gbps (about 750MB / s). The maximum transmission rate of a 3.5-inch HDD disk can reach about 270MB / s, and the maximum transmission rate of a 2.5-inch SSD disk can reach about 500MB / s.
[0052] The hard disk space of a 3.5-inch HDD disk is compatible with the hard disk space of two 2.5-inch SSD disks, which not only increases the space utilization of the 3.5-inch hard disk space, but also improves the data transmission rate.
[0053] This embodiment provides a hard disk device that is compatible with 3.5-inch and 2.5-inch hard disks.
