Do Multiple Internal Hard Drives Slow Down a Computer?

My old hard drive is still functional but has run out of storage space. I intend to purchase an SSD and install Windows 11 on it. The old hard drive will be erased and kept as a backup drive. However, I am concerned that adding multiple hard drives will cause a computer to slow down. Do you have any idea?

Having multiple internal hard drives won't affect the computer's speed inherently. However, you need to consider these factors to check if your computer has been influenced:

If you connect multiple hard drives to a computer via the same interface, like a SATA cable, the data transfer speed may be affected since all drives share the available bandwidth.
Adding multiple drivers increases power consumption, which can impact overall system performance. However, this effect is minor and can sometimes be overlooked.
Using multiple hard drives on a computer generates more heat, affecting the overall temperature inside the computer case.

If you have the above concerns and want to expand the lifespan of your computer, you'd better use one hard drive or an SSD.
