Understanding M.2 SSDs and NVMe Technology APT

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

• M.2 SSDs are faster than 2.5 inch SSDs.

• M.2 SSDs use a different form factor.

• M.2 SSDs are larger than 2.5 inch SSDs.

• M.2 SSDs are older technology.

What protocol do M.2 NVMe SSDs use for data transfer?

• SATA

• AHCI

• PCI Express

• USB

What is the theoretical data transfer speed of SATA 3.0?

• 600 megabytes per second

• 3 gigabytes per second

• One queue with 32 commands.

• 64,000 queues with 64,000 commands each.

• No command queue.

• A single command queue.

What is the main benefit of using PCI Express with NVMe?

• Slower data transfer.

• Faster data transfer.

• No benefit.

• Increased latency.

What is the main characteristic of SSDs compared to mechanical hard drives?

• They have moving parts.

• They use flash memory.

• They are slower.

• They are larger.
