Understanding Storage Devices

The video tutorial covers various storage devices, starting with traditional hard drives, their mechanical components, and limitations. It then transitions to solid-state drives (SSDs), highlighting their advantages over hard drives, such as speed and reliability. The tutorial also discusses different interfaces like SATA, mSATA, NVMe, and M.2, explaining their roles in enhancing SSD performance. Additionally, it covers flash memory, its uses, and limitations, and concludes with a brief overview of optical drives and their applications.
