SSD why not make 3.5-inch

A. The origin and difference between 3.5-inch and 2.5-inch

3.5-inch traditional hard disk is mostly used in desktops and servers, and 2.5-inch hard disk is mostly used in laptops or used as a mobile hard disk.

The former has a large capacity and strong performance, but large size, high power consumption, poor portability, low price per unit capacity, and the main cost-effective.

The latter has a small capacity, weak performance, but small size, low power consumption, high portability, high price per unit capacity, and mainly for mobile use.

For manufacturers, 3.5-inch products and 2.5-inch products require two production lines.

For consumers, the vast majority of cases the two sizes of hard disk has a clear distinction between the use of the two, but also quite peaceful.

The size of an SSD

The body of an SSD is the circuit board inside it! With current technology, SSDs can be designed in a variety of shapes and sizes to meet different customer needs, typically the SSDs used in the Fruit family's laptops are mostly custom sized.

The reason why SSDs are now being made in 2.5-inch sizes is for a number of reasons

1. Compatibility with existing laptops (straight on) and desktops (using very simple hard drive cages) to provide convenience to consumers.

2, the current price per unit capacity of SSD is much higher than traditional hard disk, in the pursuit of cost-effective and high-capacity 3.5-inch traditional hard disk in front of Alexander. And its low power consumption, anti-vibration and other advantages of the traditional notebook hard disk is a greater threat, at the same time, notebook users on the hard disk capacity of the degree of sensitivity is much lower than the desktop, so SSD is currently the main direction of the notebook. Made to the size of 2.5 inches, in fact, want to replace the traditional notebook hard disk.

3, only produce 2.5 inch a size, means no need to prepare two different sizes of production line, no doubt can reduce costs.

4, 2.5-inch SSD in the 3.5-inch rack is very easy to install, even if you do not use the adapter rack directly with the tape can be fixed, due to the size of the use of non-compliance brought about by the difficulty is very small.
