[SOLVED] Is a 2½" hard drive really slightly larger?

relztrah · Aug 12, 2022

I am wanting to replace this internal HDD with a SSD. I see them for sale but the specs have 2 1/2" whereas this HDD clearly measures more than that.

Is the 2 1/2" just rounded to the nearest half inch or are there actually 2 5/8" internal drives?

I never have measured the dimensions of the hard drive, but the form factor standards ensure that available drives will fit in the bay, the screw holes will line up, and the standard cables and connections will plug in.

I have never heard of a 2 5/8'' drive. As Freebooter mentioned, the form factor standard is stated 2.5'' and will fit in your PC.

Actual Dimensions

A 2.5-inch SATA hard drive actually measures 2.7 inches wide, 0.37 inch tall, and 3.96 inches long. According to The Tech Report, the 2.5-inch designation actually refers to the size of a typical laptop drive platter, the disc inside the housing that data is actually recorded on. The average 2.5-inch drive weighs slightly more than 4 ounces.

Thanks for the clarification. I marked the thread as SOLVED.

The measurement is the size of the disc inside the drive not the drive housing.
