Study Notes
- Upgrading from a hard drive to an SSD using the same interface is easy and can significantly improve device performance.
- SSDs come in various form factors, such as M.2 interface, which can offer smaller size and no cables compared to traditional SATA-connected SSDs.
- M.2 SSDs are modular and can be easily added to a system by plugging into a slot and securing with a screw.
- Traditional hard drives have a larger form factor and require access to the laptop's internal components to replace or upgrade.
- Replacing a hard drive with an SSD involves unscrewing covers, disconnecting the drive from the SATA connection, and sliding it out of the bay.
- To add a new drive, the user connects it to a cable, screws it down, and installs it in the laptop.
- M.2 drives are even easier to install, requiring only a single screw to connect or disconnect them from the M.2 interface.
- Performance improvements from upgrading to an SSD can be substantial, leading to common migrations of operating systems from hard drives to SSDs.
- Operating system migration can be done by installing a new operating system and moving user data and applications, or creating a clone or image of the hard drive and transferring it to the SSD.
- Many laptops have built-in wireless functionality using 802.11 or Bluetooth connections, accessible via user-replaceable Mini PCI or Mini PCI Express interfaces on the laptop's motherboard.
Test your knowledge on upgrading from a hard drive to an SSD, and the advantages of SSDs and the M.2 interface. Learn about the increased speed for reading and writing data, as well as the form factors and compatibility of these storage devices.
