SSD mounting bracket
In the past (and even now), many users have utilized an HDD (hard disk drive) as their primary storage method. However, as the prices of SSDs (solid-state drives) have come down, many consumers have transitioned to them. However, older cases still use 3.5" drive bays to house drives, which may be problematic for users as SSDs are much smaller in size. To fix this issue, an SSD mounting bracket (pictured) can be used to create a more fitting support for the smaller device in the larger bay.
Although an SSD mounting bracket is helpful, most SSDs can be secured to a larger drive bay by using only screws due to their light weight.
