How do I Choose the Best Laptop Hard Drive?

Notebook hard disks are designed for mobile devices such as notebook computers, with small size, low power consumption, and shock resistance.

General laptop hard drives are 2.5

Hard disks used in notebook computers are generally 2.5 inches, while desktop computers are 3.5 inches. Due to the different manufacturing process technical parameters of the two, first,

But laptop hard disks have a parameter that desktop hard drives do not have, which is thickness. Standard laptop hard disks have four thicknesses of 7,9.5, 12.5, and 17.5mm. The 9.5mm hard disk is designed for ultra-light and ultra-thin models. The 12.5mm hard disk is mainly used for thicker optical-soft interchangeable and fully built-in models. As for the 17.5mm hard disk, it was the product of the previous single-disk capacity. Basically no models are used.

The fastest laptop hard drive now is 10000 to 64M Cache,

Laptop hard drives generally use three forms to connect to the motherboard: hard drives

As applications become larger and larger, the capacity of hard disks is also getting higher and higher. For the hard disks of notebook computers, not only its capacity is large, but its size is also small. In order to resolve this contradiction, the hard disk of laptop computers generally uses magnetoresistance

From the perspective of product structure and working principle, there is no essential difference between laptop hard drives and desktop hard drives. The biggest feature of laptop hard drives is their compact size. At present, standard products have a diameter of only 2.5 inches (1.8 inches or even smaller). It is also much thinner than a 3.5-inch hard drive. Generally, the thickness is only 7mm-12.5mm, and the weight is about one hundred grams, which is called small and exquisite. The small internal space of a notebook computer, the inconvenient heat dissipation, and the limited battery energy, coupled with the unavoidable bumps during movement, place high demands on the volume, power consumption, and ruggedness of its components.

Laptops use 2.5-inch hard drives, compared to 3.5-inch desktops, which are also more expensive than desktops. As applications become larger and larger, and the capacity of the hard disk is also getting higher and higher, when purchasing a machine, the capacity of the hard disk should have an expansion consideration. The hard disk is the most fragile and fragile part of a notebook computer. In normal use, pay special attention to anti-shock and anti-fall, and make more backups.

However, the performance gap between notebook hard drives and desktop hard drives is still huge. When desktop hard drives have reached the mainstream speed of 7,200 rpm, notebook hard drives still have mainstream speeds of only 5,400 rpm, and hard drives have become the majority of notebooks. Performance bottlenecks. In pursuit of thinner and lighter, 1.8-inch notebook hard drives have appeared. ^[1]
