M.2 SSD and NVM Express CA-211б

What is the main difference between a regular 2.5 inch SSD and an M.2 SSD?

• M.2 SSDs have more storage capacity

• M.2 SSDs use a different type of flash memory

• M.2 SSDs use a different form factor and connect to a different type of slot

• M.2 SSDs are slower than 2.5 inch SSDs

What is the main reason why SSDs are faster than mechanical hard drives?

• SSDs use flash memory for data storage

• SSDs have more moving parts

• SSDs have a larger form factor

• SSDs use a different type of interface

What was the interface standard widely used for hard drives and SSDs before M.2 and NVM Express?

• SATA 3.0

• PCI Express

• USB 3.0

• AHCI

What is the theoretical data transfer speed of the SATA 3.0 bus with AHCI?

• 600 Megabytes per second

• 300 Megabytes per second

• 1200 Megabytes per second

• 900 Megabytes per second

What type of bus do M.2 NVM Express SSDs use instead of the SATA bus?

• USB bus

• PCI Express bus

• Thunderbolt bus

• FireWire bus

What is the data transfer rate of M.2 NVM Express SSDs?

• 4 Gigabytes per second

• 2 Gigabytes per second

• 1 Gigabyte per second

• 3 Gigabytes per second

What is the main advantage of NVM Express over AHCI?

• NVM Express has a larger form factor

• NVM Express has more moving parts

• NVM Express reduces CPU overhead and increases input/output operations per second

• NVM Express uses a different type of flash memory

What is the maximum number of commands that NVM Express can fulfill in theory?

• 2 million commands

• 4 million commands

• 1 million commands

• 4 billion 96 million commands

How does the M.2 SSD connect to the motherboard?

• It slides into the spring-loaded slot and is tightened down with a single screw

• It connects with a connection cable

• It connects with a separate power cable

• It connects to the CPU

What is important to check before using an M.2 NVM Express SSD?

• The size of the SSD

• The motherboard support for M.2 slot and NVM Express technology

• The color of the SSD

• The type of flash memory used
