The advantage of a solid-state drive (SSD) over a hard disk drive (HDD) is primarily its speed. SSDs offer significantly faster read and write speeds compared to HDDs, leading to quicker boot times, faster file transfers, and improved overall system responsiveness.
Therefore, the best way to frame the advantage among the options you provided would be:
"SSD offers a speed between 50 to 250MB/sec."
However, it’s worth noting that many SSDs can achieve speeds much higher than that, especially modern NVMe SSDs, which can reach several GB/s. But in general, SSDs are known for their speed advantage over HDDs.
