Optical drives
Examples of mass storage device interfaces include: (Select all that apply)
- UTP
- SATA
- HDMI
- IDE/PATA
- STP
- SCSI
SCSI
IDE/PATA
UTP
When installing two PATA drives on a single cable, each drive must be configured with a jumper to designate it as either a primary drive (a.k.a. “master”) or a secondary drive (a.k.a. “slave”). The “cable select” jumper setting option automatically configures the drive as master or slave according to its position on a cable.

Which of the following are examples of SSD host interfaces? (Select 3 answers)
- MAPI
- M.2
- PCIe
- GDI
- SATA
- ACPI
- M.2
- PCIe
- SATA
An M.2 key is a notch on the pin contact surface of an M.2 expansion card which prevents insertion into an incompatible socket. The M.2 key IDs include 12 available letters from A to M. These letters correspond to the locations of notched pins on the card’s contact surface and designate which interface the card is compatible with. M.2 expansion cards that are used for solid-state storage applications have key IDs of B and M. The B-keyed M.2 SSD cards use 2 PCIe lanes (lower read/write speed), while M-keyed M.2 SSDs use 4 PCIe lanes (higher read/write speed). M.2 SSDs with 2 notches on the card’s pin contact surface (B + M) increase the card’s compatibility as they can be installed in either of the two types of expansion slots on the motherboard.
True or False?
