What is the key trade-off between HDDs and SSDs?

• A. HDDs offer larger capacity at lower cost but are slower; SSDs are faster, more durable, but more expensive per gigabyte.
• B. HDDs have higher performance than SSDs but with less durability.
• C. SSDs store data magnetically and are slower than flash drives.
• D. HDDs use PCIe interfaces while SSDs use SATA.

Answer: (A)

When deciding on storage, the key idea is balancing capacity and cost with speed and durability. HDDs store data on spinning disks, so you can get a lot of storage for a low price, but the mechanical parts make them slower to access and more vulnerable to damage. SSDs use flash memory with no moving parts, which means much faster data access, quicker boot and load times, and better durability, but they cost more per gigabyte. That combination—large capacity at a lower cost but slower performance versus faster, more durable operation at a higher price per gigabyte—is why the described trade-off is correct.
