One minute to help you understand the differences between mSATA and mini PCI-E？

.

It looks that many non-professional friends often do not understand the difference between mSATA and mini PCI-E. Today, NOVORAY will take you to understand the difference between the two in a minute.

Point 1: Definition of mSATA interface

The mSATA interface is in the all-in-one machine with the standard SSD, and its shape is exactly the same as the mini PCI-E interface, all of which are 54Pin pins, so it is very easy to be confused, but the mSATA interface is installed with a full-height card, and some models will also mark the words near the interface, so you should pay attention to distinguish.

Since the mSATA interface is based on the SATA bus, the transfer speed is much higher than that of the mini PCI-E interface, and there is no commonality between the two, for example, the SSD with the mini PCI-E interface cannot be used on the mSATA interface.

The second point: the definition of mini PCI-E interface

If the all-in-one computer is wireless, it will be equipped with this interface, because the wireless network card has become the standard configuration of the all-in-one machine. It is based on the PCI-E bus, which can expand peripheral devices for the all-in-one machine, such as Bluetooth module, 3G module, wireless network card module, and solid-state drive with mini PCI-E interface. However, the mini PCI-E interface does not have a high bandwidth, so it is more suitable for some peripheral devices that do not require very high data throughput. Some motherboards have multiple mini PCI-E ports inside, and in addition to the built-in wireless network card, at least one more will be reserved for the 3G module (and the antenna is pre-embedded). Although the interface of the two is common, there is a difference between a “half-height card” and a “full-height card”, so you should pay attention to it when purchasing a module.

It can be simply understood as:

1. The mSATA interface is the same as the mini PCI-E physical interface,And inserting it will not burn the card.。

2. First, there is the mini PCI-E standard, and then notebook manufacturers use this port to make wifi cards, 3G network cards, sound cards, and so on.

The mini PCI-E host device supports both PCI-E and usb2.0 signals, as for which one to go, it is up to the card inserted to decide by itself.

3. Some accessories manufacturers have made mini PCI-E interface SSDs, which are basically PATA protocols. The maximum sequential read/write speed < 80M.

4. The mSATA standard appeared, using the mini PCI-E interface to transmit SATA signals… As for why this is so, I have never figured it out.

5. Whether the notebook can use mSATA or not depends entirely on the manufacturer’s definition and configuration. At present, Lenovo is supporting relatively well.
