A

NVMe

SATA

PCIe

18
Q

A logical device interface used for accessing non-volatile memory storage devices attached via PCIe is known as:
GDI
NVMe
SLI
MAPI

A

NVMe = nonvolatile memory express

19
Q

Which of the following answers refer to SSD form factors? (Select 2 answers)
PCIe
M.2
mSATA
NVMe
SATA

A

M.2 = small form factor solid-state drive

mSATA = A type of solid state drive same as M.2

20
Q

An M.2 key is a notch on the pin contact surface of an M.2 expansion card which prevents its insertion to an incompatible socket. The 12 available M.2 key IDs are letters from A to M which indicate the location of notched pins on the card’s contact surface and designate the type of interface a given card is compatible with. M.2 expansion cards used for solid-state storage applications have key IDs of B and M. The B-keyed M.2 SSD cards take advantage of 2 lanes of a PCIe link (lower read/write speed), the 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 any of the two types of expansion slots on the motherboard.
True
False

A

True

21
Q

Which of the answers listed below refers to an older, portable device SSD form factor superseded by M.2?
