Most of the Laptop users don’t know much about internal hard disks they have. On the other hand new laptop buyers least consider about hard disk specifications. In this video I demonstrated one laptop internal 2.5 inch hard disk.
Hard drives are the most common medium of storage in a laptop. The first factor towards performance of the laptop is the speed of the hard drive. In most cases, laptop hard drives spin at a 5,400rpm speed. Some higher performance systems and desktop replacements will feature 7,200rpm drives. The high spin rate allows for better performance but also uses up more battery life when not plugged into an outlet. Conversely, some use the 4,200rpm speed with lower performance but these are extremely uncommon now. Laptop drives are typically 2.5 inches in size and can range from 160 GB up to 1 TB in size. All these details are explained in this video.
