An SSD, or solid state drive, is a non-mechanical device that uses non-volatile memory (generally NAND) to store data. An HDD, or hard disk drive, is mechanical and stores data on spinning platters as magnetic marks. Read/write heads traverse the platter to seek and transfer data. Because of all the moving parts on an HDD, they have a higher chance of failure over time.
Tested: These are the best SSDs you can buy right now… PCIe 5.0 is even faster -- up to 15GBps with storage. NVMe: Non-Volatile Memory Express technology takes advantage of PCIe’s bountiful bandwidth and the unique properties of NAND such as multiple lanes and caching to create blisteringly fast SSD performance. …
