Preface
Do you have any ideas for upgrading the hard disk of your computer? If there is, then just follow this post to do a hard disk upgrade for the computer.
To upgrade a hard disk for a computer, you must first know how many interfaces the hard disk has. If you don't know how many kinds of connections there are, then there is no way to choose the most suitable hard disk for your computer.
The most direct way is definitely to query the motherboard model of the computer, know the model, you can know how many interfaces can be connected to the hard disk on the computer.
This post can be said to be very detailed, but there are also some interfaces that will not be covered, such as very old IDE interfaces
There is also the SAS interface (very similar to SATA) and the U.2 interface used on the server
There are also hard disks with Pcie interfaces, and we won't talk about them (mainly because they're too expensive)
The body begins
In 2024, we basically use the following hard disk interfaces: m.2, Sata, and mSata. Today, let's talk about these interfaces:
M.2 interface
There are many types of m.2 protocols, and there are basically two types of protocols: NvMe protocol and SATA (Ngff) protocol.
NvMe protocol
In the NvMe protocol, it is also divided into Pcie5.0*4, Pcie4.0*4, Pcie3.0*4 and so on, how to choose a suitable hard disk has become a problem, and many friends can't distinguish these contents.
Pcie5.0*4
The hard disk of this protocol is the fastest single hard disk in the consumer class today, and the interface also supports PCIe5.0, and the continuous read and write speed easily exceeds 10000MB/s, and it is not excluded that it is below 10000MB/s.
Pcie4.0*4
The hard disk of this protocol is considered to be the second echelon of the second echelon of single read and write speed in the consumer class today, and the interface also supports PCIe4.0, and the speed easily exceeds 7000MB/s. Of course, there are also some hard disks with a read and write speed of about 5000MB/s.
These values depend on the actual configuration of the computer, and there are many practical factors that affect it, but the read and write speed will not be bad.
Pcie3.0*4
As for the hard disk of this protocol, it is also very fast to read and write, and the single read and write speed will not exceed 4000MB/s, and if it can run to 3500MB/s, it is already very high.
Note: After buying an M.2 SSD, don't forget to see if there is a corresponding heatsink, otherwise the hard drive will easily burn out.
- For those who use SSDs, please note that hard drives are easy to break without this thing!
SATA Protocol
Some computers support the NvMe protocol on the first interface, but only support the Sata protocol on the second interface. There are also some computers that only support the Sata protocol M.2 interface SSD. The specific content of the manufacturer will be marked in the details page, and you only need to query the corresponding motherboard model.
SATA interface
This interface is a more general-purpose hard disk in the current situation (in the case of alternating between old and new computers), and the shape is very similar to that of a 2.5-inch mechanical hard disk. The sequential read and write speed of the hard disk with this interface will basically not exceed 550MB/s, but it can be used on almost every machine, as long as the computer has a Sata interface, it is possible.
mSATA interface
This interface is very common on older all-in-one computers or laptops, and the shape is similar to miniPcie.
The screws that fix the hard disk are in the corners, which is the mSata interface. The read and write speeds are the same as those of the SATA interface, and the maximum speed is not more than 550 MB/s.
--End--
If you want to know what interfaces your computer has, the easiest way is to take it out and look at it.
If you can't see it, then find the corresponding model directly online.
