Reason: Due to study and project needs, the original 256G solid state can no longer meet the demand. The price of the official after-sales expansion hard drive is too touching... (poor students have no money), and the weight and noise of the mechanical hard drive are not very ideal, so the solid state drive is chosen.

Official expansion information
Put down the expansion configuration information table on the previous official website.
In addition, there are powerful netizens who have done experiments.
In addition, netizens said that M2 only supports 512G at most.

First of all, I thought of looking for after-sales service from Huawei, but I called and asked two times and either told me that I could not install it, or I was unwilling to do it. Finally, I contacted a nearby service point. The after-sales guy was very patient and willing to help me install it, but I have to choose the hard disk model and interface... so I started the long road of hard disk selection.

SSD classification (from Baidu)
Specifically divided into seven types: U.2 | SATA | PCI-E | Macbook | MSATA | M.2. Among them, MSATA M.2 is a mini interface.
M.2 has the NVMe protocol, and M.2 (SATA) means that the interface has the same shape, but the protocol is different. The former is faster, and the latter is a hard disk with traditional speed
SATA interface :
this type is now a traditional interface, and it is the mainstream interface in the market. It is widely used on mechanical hard disks. For compatibility, the interface of solid-state hard disks is also of this type.
Matebook D itself has an expansion hard disk space, but it is designed as a combination of solid state + mechanical hard disk
Huawei MateBook D 8G+256G model. The M.2 SSD hard disk used by this machine
uses the M.2 interface of the sata channel, so Master Lu will recognize it as sata. In addition, the M.2 interface supports the NVMe protocol, but because it uses the sata channel, the speed cannot be exerted (only Limited to 2018 matebook D), so you need to buy a 2.5-inch 7mm SATA interface solid-state drive
Here I would like to thank the gods on the Huafen forum, DIY disassembly tutorial (I refer to this to determine the hard disk model)
In addition, an adapter cable is required.
The hard disk is a Western Digital blue disk. I feel that the medium level meets my needs.

I contacted the after-sales guy and chose to go to the store to install it on the service day
installed
It appears that the device has not been migrated...
change the manual to automatic, and then restart, but the customer service said it will not affect
Checked out the new disk, the condition is very good~~
Use it for a while to see if there are any bugs
