STC PCIE 4.0 to u.2 expansion card review

With the continuous development of 4.0 high-speed NVME storage technology, users are beginning to choose U.2 interface hard drives as their storage devices because of security. After all, data is priceless, and enterprise-level high security and long-life U.2 have become one of the safe and stable solutions for users. However, users also face the problem that the motherboard does not support the U.2 interface. In order to solve this problem, we tested several similar cards and found that STC's PCIE 4.0 to U.2 expansion card can meet the requirements well in terms of ease of use, speed and heat dissipation.

1. U.2 hard drive is plug-and-play and does not require disk selection.

This PCIE 4.0 to U.2 expansion card from STC adopts a plug-and-play design. I only need to insert the U.2 interface hard disk into the expansion card, and then insert the expansion card into the PCIE X4 and above interfaces of the motherboard 4.0 , you can identify and use it without driving. This design facilitates user operation and is very simple.

2. PCIE 4.0 high-speed operation up to 7000M/S

The PCIE 4.0 to U.2 expansion card uses the PCIE 4.0 interface, and the theoretical bandwidth can reach up to 64Gbps. In the actual test, we only had 3.0 U.2 disks on hand, so we used a 4.0 980PRO NVME interface hard drive with faster read and write speeds. The test results showed that it could reach a read speed of 7100MB/s, 5100MB/s. The writing speed of S fully meets the needs of most users. At the same time, due to the use of PCIE 4.0 interface, it is also backward compatible with U.2 of PCIE 3.0, making one card capable of multiple functions.

3. High cost performance

Compared with buying a motherboard with its own U.2 interface, this card is more affordable and can support U.2 interface hard drives without changing the motherboard.

4. Suspended design

The biggest difficulty in increasing the heat dissipation space of U.2 is heat dissipation. We also bought several other expansion cards. Many manufacturers use thermal conductive silicone to meet the requirements, but the actual measurement results are average. After testing several cards, We found that the STC expansion card solution with a suspended design is different. It separates the card and disk with nuts to increase the heat dissipation space, so that the U.2 disk is not directly next to the card, and then through the tape The iron sheet with holes and the hollow design can help reduce the temperature of the disk. The measured temperature can be reduced by nearly 10%. Although it is only a little higher, it is indeed very practical for heat dissipation.

Summarize:

STC's PCIE 4.0 to U.2 expansion card features plug-and-play, high-speed transmission, high cost performance, and suspended design. It can meet users' needs for U.2 interface hard drives and also has high stability and heat dissipation. Effect. For those users whose motherboard does not support U.2 interface, this expansion card is the best choice.
