Why can't the M.2 SSD be recognized after installation?

When using an SSD for the first time, it needs to be formatted and partitioned first. You can use "Disk Management Tool" to format and partition the SSD, and then use it in "Windows Explorer".

Why is the product capacity displayed on the computer not 1TB or 2TB?

Because the manufacturer's calculation method is 1TB=1000MB=1000000KB=1000000000B, and the computer system's calculation method is 1TB=1024MB=1024*1024KB=1024*1024*1024B, so the capacity you see is 1TB=(1000*1000*1000)/(1024*1024*1024)TB≈0.93TB.

Why does the test speed of Fanxiang S660 NVMe SSD fail to reach 5000MB/s?

The nominal speed is tested when connected to the PCIe Gen 4x4 interface. If connected to a PCIe Gen 3x4 interface, speed will be limited to 3500MB/s. If you use it in an SSD enclosure, the speed will be limited by the speed of the enclosure.

Why do I need to install the heatsink of the S660 M.2 SSD myself?

Considering that some buyers install it inside a laptop or desktop, we distinguish the M.2 SSD from the heatsink.

In the future, we will install heatsinks on all products and then send them to Amazon.
