What brand to choose for SSD M2 and what does M2 SSD mean

This choice of brand still depends on how much money you need to buy, if the budget is sufficient. Samsung and Intel's SSDs are the best, while neither the 970evo Plus nor the 760p model SSD'Wrong, Western Digital SN750 is also OK, if you are pursuing cost-effective, Hikvision C2000 and ADATA S40G S11 are also available,

The first brands that use the original films, such as Intel, Samsung, Critical (Micron), Kioxia (Toshiba) Puket, are guaranteed to have stability and longevity, and secondly, the mid-to-high-end products of major brands, such as the Western Digital Blue Disc SN series and above, Kingston UV series and so on, are all original films.

M2 hard disk refers to the use of interface of the solid state drive, SATA is also a kind of hard disk interface standard, the two are different, the difference is as follows:

1. Different transmission methods.

1. M2 hard disk: using PCI-E 2 interface standard, the maximum read speed can reach 700MB s, and the write speed can also reach 550MB s. Socket 3 can support PCI-E 4 interfaces, with a theoretical bandwidth of up to 4GbS.

2. SATA: Transmit data in a continuous serial manner, and can use a higher working frequency with less bit width to improve the bandwidth of data transmission.

Second, the characteristics are different.

1. M2 hard disk: You can set the key slot on its interface to realize the interface of different functions.

2. SATA: Only 1 bit of data will be transmitted at a time, which can reduce the number of pins in the SATA interface, reduce the number of connecting cables, and the efficiency will be higher.

Third, the advantages are different.

1. M2 hard disk: Whether it is a smaller size or higher transmission performance, it is far better than SATA.

2. SATA: SATA bus uses embedded clock frequency signals, which has stronger error correction capabilities than before, and can check the transmission instructions (not only data), and automatically correct if errors are found, improving the reliability of data transmission.

M2 is an interface, and there are generally two interfaces, M2 and SATA, and M2 is generally faster than SATA.

SSDs are good.

SSDs that use PCI-E lanes are faster than SSDs, and SSDs that use SATA channels are just as fast as SSDs.

SATA interface is the most popular and compatible data interface for SSDs, and can be found on every motherboard, with the highest version being up to 6Gbps theoretical bandwidth. The transport interface is a new interface specification introduced by Intel to replace the mSATA interface, which is smaller and more powerful.

Although the interface has the same form factor, it supports two types of channels, namely SATA channel and PCI-E channel. If the interface uses SATA channel, its transmission speed is not much different from the speed of the SSD SSD of SATA data interface, and the bandwidth is only 6Gbps, and the difference between them is the difference in interface and shape.

The data interface using the PCI-E channel is different, the data through the PCI-E channel is directly connected to the CPU, eliminating the process of memory transfer, which can maximize the transfer speed, and the theoretical speed of this interface can reach 32Gbps, which is more than five times higher than the SSD solid state drive of SATA data interface.

Although MSATA's SSD is small enough, it still doesn't have any advantages over interfaced SSDs. Standard SSDs, like MSATA, can be arranged with single-sided NAND flash memory particles or double-sided, where the total thickness of the single-sided arrangement is only and the thickness of the double-sided arrangement is only.

The disadvantage of msata in terms of volume is much more obvious, the size of 51mm and 30mm makes msata not dominant in area, and the thickness of the single-sided arrangement is too thick compared to it. In addition, it can provide higher storage capacity even when the size is the same.

First, the configuration of the two is different:

1. SATA SSD configuration: SATA SSD provides a variety of customized design services, and can be customized according to different needs in the parts of organization, security data protection mechanism, connector and certification standards.

2. The configuration of M2 SSD: The intelligent combination of M2 SSD, the recorded ** file can be stored in the hard disk of Xiaomi router, and can be recorded in a loop for 1 day, 1 week or 1 month. If the M2 SSD is not suitable, the user will also be notified to make adjustments.

Second, the performance of the two is different:

1. SATA SSD performance: SATA SSD can determine the location of commonly used WiFiap according to the positioning of the base station, and search for matching SSIDs in the background, which has the advantages of simple structure and hot-swappable.

2. The performance of M2 SSD: M2 SSD has a stronger error correction ability, and its biggest difference compared with the past is that it can check the transmission instructions (not only data), and if errors are found, they will be automatically corrected, which greatly improves the reliability of data transmission.
