HDD |
Hard Disk Drive The HDD is typically found in 2.5" or 3.5" form factors. They read and write data to spinning disks, or platters, which is measured in revolutions per minute (RPM). |

SSD |
Solid-State Drive The SSD reads and writes data using flash memory. Unlike the HDD, the SSD has no moving parts so it’s less prone to mechanical failure. The SSD is also much faster than the HDD in terms of data transfer rates. |
