How to choose an obstacle hard disk upgrade?

What is the most scientific way of raising the hard drive in the old book? Is it a matter of planning or buying, whether it is a good choice or not? In fact, the choice of upgrading the laptop hard drive is still quite awkward, today Xiaobian devoted to an article on the hard drive upgrade.

Older upgrade look at the interface

Notebook upgrade is not just to buy a piece on the line, and now there are so many hard disk interfaces, SATA, mSATA, M.2 (SATA / NVME), buy wrong may even have difficulties in installation.

First attach a few pictures, let everyone distinguish between different interface hard disk status

SATA interface

mSATA

M.2 2242/2260/2280

Among them, SATA is both solid state and mechanical hard disks, and all others are all interfaces used by solid state hard disks.

Specific to the upgrade method, there are three options for everyone to choose. First of all, look at what interfaces are in your computer. One is a 2.5-inch SATA disk + one mSATA/M.2 disk. If so, it is necessary to study it. It is to buy a large-capacity SATA disk. Interface solid state is good, or buy a small-capacity mSATA / M.2 SSD, a solid-state + mechanical combination?

Replace 2.5-inch SATA SSD

First of all to say, in fact, only mechanical hard disk laptops, buy a standard 2.5-inch solid state drive into the line, do not have to consider the interface speed problem. However, the 2.5-inch mechanical hard disk, solid-state hard drive worth mentioning, but need to pay attention to this - in recent years, notebooks are focused on thin, many models of 2.5-inch hard drive bits are ultra-thin design, which can only accommodate 7mm thickness The hard disk, fortunately nowadays mechanical hard drives and SSDs are also mainly 7mm thick;

If the notebook's 2.5-inch hard drive is designed for 9mm thickness, then it needs to use gaskets. Generally, a solid-state hard drive will send one, which can be “changed” from 9mm to 9mm thick.

Remove the mechanical hard disk, you can buy a hard disk box as a mobile hard disk to use, it should be noted that the current mobile hard disk box is basically designed according to 9mm thickness, but the interior is either a gift gasket, or there is a sponge cushion, completely no need to worry.

mSATA/M.2+2.5 inch SATA mechanical hard disk

It is undoubtedly the most economical option to retain the original mechanical hard disk as a storage warehouse, and then purchase a medium- and small-capacity SSD. On the one hand, it has effectively solved the problem of speedup of solid-state drives, and on the other hand, it still retains a large-capacity storage space, which can serve two purposes. The only drawback is that this increase in power consumption will reduce the battery life when the notebook is using batteries.

If the notebook has mSATA interface, it should be noted that this interface has been basically replaced by the M.2 interface, but the industrial control equipment is still in use. This also led to a problem, the brand's mSATA solid-state hard drive is relatively small, the choice is also small, but you must pay attention to, those unknown brand goods do not buy, after all, who said that this kind of no-name products used storage Particles are not genuine.

Next is the M.2 interface, which is a bit complicated. M.2 interface SSDs are actually divided into NVME bus and SATA bus. The former is faster. The latter is the same speed as ordinary SATA/mSATA interface. The highest is SATA 3.0 level. Therefore, when purchasing, be sure to tell the store specifically what you want to say. If you don't understand it completely, then tell the store model to the laptop, let him help you inquiries.

Single interface type notebook how to upgrade?

Finally, there is an ultra-thin notebook computer, only M.2 interface, it may be two to three, completely canceled the 2.5-inch notebook hard drive, such as Ultrabooks and so on. In this case, there is only one upgrade option. Replace the larger-capacity M.2 interface SSD.
