What are the differences between hard disk drives and solid state disks? (Choose two correct answers.)

Hard disk drives contain a motor that spins magnetic platters and mechanical read/write heads that physically move to locate data, whereas solid state drives store data in NAND flash memory chips that have no mechanical components whatsoever.

SSDs can and do fail due to NAND flash wear-out from write cycles, controller failure, and power loss corruption, so the claim that SSDs cannot fail is factually incorrect.

SSDs do not inherently store more data than HDDs - HDDs typically offer larger raw capacities at lower cost per gigabyte, and storage capacity is independent of the HDD/SSD distinction.

The Linux device node /dev/sda refers to the first detected block storage device regardless of whether it is an HDD or SSD; there is no /dev/ssda device naming convention in Linux.

SSDs provide much faster data access than HDDs because they eliminate seek time and rotational latency entirely - data is retrieved electronically from flash cells rather than waiting for a physical head to position itself over a spinning platter.
