Why each option
Laptop (2.5-inch) hard drives are physically narrower than desktop (3.5-inch) drives to fit within the slim profile of portable computers.
2.1 inches is not a recognized standard hard drive form factor width.
The industry standard physical width for laptop hard drives and SSDs in the 2.5-inch form factor is exactly 2.5 inches (63.5 mm), which is defined by the SFF-8201 specification and differentiates them from the 3.5-inch desktop form factor.
2.8 inches is not a recognized standard hard drive form factor width.
3.5 inches is the standard width of desktop hard drives, which are too large to fit inside a laptop chassis.
