早些年笔记本还是机械硬盘的天下,选硬盘非常简单,要么500G,要么1TB。讲究点的还会看看转速和缓存大小。不过这一两年,固态硬盘异军突起。固态硬盘的读写速度,尤其是小文件随机读写速度比机械硬盘有了很大的提高。性能优势明显,所以也开始在笔记本中普及起来。现在笔记本中常见的硬盘组合有4种:

(1).

纯机械硬盘(一般是500G或者1TB)

(2).

混合硬盘SSHD

(3).

双硬盘(固态+机械)

(4).

纯固态硬盘(常见128G、256G和512G)

4种方案中,除了混合硬盘不值得选购(实际性能和纯机械硬盘相差很小)的之外。其他3种都可以考虑。不过值得注意的是第1种,因为现在普遍认同机械硬盘是电脑硬件系统中的最后一道性能瓶颈。所以除非你预算特别紧张,否则购买纯机械硬盘之后,我强烈建议你加(改)装固态硬盘。相应的升级方案也有3种:

▲第一种:直接拆掉机械硬盘,换固态硬盘。换下来的硬盘可以当移动硬盘用。改装完了之后就相当于纯固态硬盘。这个方案理论上是性能最好的,适合对硬盘容量需求不大的朋友。

▲第二种:如果笔记本有光驱的话,可以拆掉光驱。用光驱位硬盘托架,将笔记本电脑自带的机械硬盘装到光驱的接口上。新买的固态硬盘就可以装在原本机械硬盘的位置上。改装完了之后就相当于固态+机械的双硬盘方案,兼顾了高性能和大容量的需求。

▲第三种:现在许多采用新模具的笔记本,会在主板上预留一个mSATA或者M.2接口。只要购买相应规格的固态硬盘,装上去就能实现固态+机械双硬盘了。效果和第二种方案一样。但不用拆光驱,更加简单。但只有一部分笔记本会有预留接口。所以在购买前最好问清楚客服,如果能找到同型号笔记本的拆机图片看看就更加稳妥了。

再次强调:只要你不想电脑卡,固态硬盘就是必须的。FTP

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:


(1).


Pure mechanical hard disk (generally 500g or 1TB)


(2).


Mixed hard disk sshd


(3).


Dual hard disk (solid state + mechanical)


(4).


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
