Can pcle4.0 install pcle3.0 solid state?

Can. The PCIe 4.0 interface is backward compatible, which means that a PCIe 3.0 hard drive can be plugged in, but the speed can only be expressed as the speed of a 3.0 hard drive, and the high-speed protocol of the 4.0 interface cannot be used; the speed limit (bandwidth) has been reduced at least Losing half of it means failing to utilize the full strength of the motherboard’s M.2 SSD interface.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

PCI Express (PCIe) is a computer bus interface standard used to transfer data between a computer's motherboard and external devices. PCIe 4.0 and PCIe 3.0 are two different versions of the PCIe standard.

PCIe 4.0 requires new hardware and drivers to support, so it cannot be used on older systems. At the same time, because PCIe 4.0 is not very common yet, not all devices support this standard. If you're upgrading hardware, you'll need to make sure your system can support PCIe 4.0 and that the required devices can support it.

The PCIe4.0 interface is backward compatible, which means you can plug in a PCIe3.0 hard drive, but the speed can only be expressed as the speed of a 3.0 hard drive, and the high-speed protocol of the 4.0 interface cannot be used. The speed limit (bandwidth) is cut at least in half, which means that the full strength of the motherboard's M.2 SSD interface cannot be used.

Extended knowledge: The difference between pcie4.0 and pcie3.0

1. Transmission rate

The data transmission speed of pci-e4.0 is much faster than that of 3.0, which can be said to be twice that. 4.0 has a two-way bandwidth of 32GB per second, while 3.0 can only reach 16GB per second.

PCIe 4.0 offers faster data transfer speeds of up to 16 GT/s, twice as fast as PCIe 3.0 (8 GT/s). This means that the PCIe 4.0 interface can transfer more data and complete tasks faster.

2. In terms of bandwidth

PCIe4.0 ×16 bidirectional bandwidth reaches 32GB/s, which is almost twice that of PCIe 3.0.

PCIe 4.0 also supports more bandwidth, up to 69.6 GB/s, while PCIe 3.0 only supports up to 32 GB/s. This means PCIe 4.0 can better support high-bandwidth applications such as video editing and 3D rendering.

3. In terms of performance,

pci-e4.0 is directly compatible with 3.0 devices, but 3.0 is not upward compatible. This is what is commonly said. backward compatibility. pcie4.0 is backward compatible with PCIe3.0 to meet the needs of more users; finally, it is based on large bandwidth, with more connections, and can connect more devices without worrying about performance degradation.

4. In terms of the number of connections,

pci-e4.0 has one higher bandwidth than two, so it can connect to more devices without worrying about performance degradation. But in fact, if you make a comprehensive comparison, especially in the process of playing games, the highest difference between the two should be about 1%, so in fact, compared to 3.0, the performance improvement of 4.0 can basically be ignored Not counted.
