Built-in HDD pockets

Internal

— pockets designed to fit inside a PC, laptop or server case.

Such devices can perform different functions, depending on the specialization (for more details, see "Purpose"). So, in laptops, pockets are used to install internal drives in a "non-native" seat. In PCs and servers, the specifics of such devices are somewhat different — they are often used to provide the ability to quickly move drives from one case to another. However, there are also solutions that play the role of adapters — in particular, for installing 2.5" drives in 3.5" slots and for connecting M.2 format SSD modules to PCIe slots for expansion cards.
