In the context of a laptop, a caddy refers to a device that provides a way to add an additional hard drive or solid-state drive to a laptop computer. The caddy typically takes the form of a tray that fits into a laptop’s optical drive bay, allowing you to install a second drive in the same space that would normally be occupied by a CD or DVD drive.
Using a caddy can be a convenient way to upgrade the storage capacity of your laptop without having to physically replace the internal drive. It can also be useful for replacing a failed hard drive without having to open up the laptop case.
Some caddies are specifically designed for use with 2.5-inch drives, while others can accommodate both 2.5-inch and 3.5-inch drives. When choosing a caddy for your laptop, it is important to consider factors such as compatibility with your laptop’s drive bay, the size of the drive you want to install, and the type of interface (e.g., SATA, NVMe) required for your drive.
