About the hard disk
In the early years, notebook was still the world of mechanical hard disk. It was very simple to choose hard disk, either 500g or 1TB. Pay attention to point will also look at speed and cache size. But in the past two years, solid-state drives have sprung up. The read-write speed of solid-state drive, especially the random read-write speed of small files, is much higher than that of mechanical drive. The performance advantage is obvious, so it also began to be popular in notebook. There are four common hard disk combinations in notebook now:
Pure mechanical hard disk (generally 500g or 1TB)
Mixed hard disk sshd
Dual hard disk (solid state + mechanical)
Solid state drive (128G, 256g and 512g)
Among the four schemes, except that the hybrid hard disk is not worth purchasing (the difference between the actual performance and the pure mechanical hard disk is very small). The other three can be considered. However, it is worth noting that the first, because it is now generally agreed that the mechanical hard disk is the last performance bottleneck in the computer hardware system. So unless you have a very tight budget, I strongly recommend that you add (change) the solid-state drive after you buy the pure mechanical hard disk. There are three corresponding upgrade schemes:
▲ the first type: directly remove the mechanical hard disk and replace it with a solid-state hard disk. The replaced hard disk can be used as a mobile hard disk. After modification, it is equivalent to a solid-state drive. This scheme is the best in theory, and is suitable for the friends who have little demand for hard disk capacity.
▲ the second kind: if the notebook has an optical drive, you can remove the optical drive. Use the hard disk bracket of the optical drive to install the mechanical hard disk of the laptop on the interface of the optical drive. The newly purchased SSD can be installed in the original location of the mechanical hard disk. After the modification, it is equivalent to the solid-state + mechanical dual hard disk scheme, taking into account the needs of high performance and large capacity.
▲ the third type: now many laptops with new molds will reserve an msata or m.2 interface on the motherboard. As long as the corresponding specifications of the solid-state drive are purchased, the solid-state + mechanical dual hard disk can be realized. The effect is the same as the second scheme. But it's simpler without removing the drive. But only a few laptops have reserved interfaces. So it's better to ask the customer service before purchasing. If you can find the pictures of the same type of notebook, it's more secure.
Again: as long as you don't want a computer card, a solid-state drive is a must. FTP
