5.0 out of 5 stars It Works
By Krado on 5 December 2020
"Converts M.2 port (M key) into one PCI-E x4 interface"
- Yes, it does.

"Includes optional low-profile expansion slot"
- Handy, for I have a spare slim HTPC case which I might use this for in the future.

"No driver installation required"
- Yup, none.

I bought this because I have a spare NVMe drive and an Athlon 3000G system. As you may know, the processor only supports up to a max of 6 PCI-e lanes in a x4 + x2 configuration. The Gigabyte B450M-DS3H only has one M.2 slot and I only had 4 solutions:

1) Buy a Ryzen w/ Radeon processor: $200+
2) Buy a new mainboard with a secondary M.2 slot controlled via the chipset: $120+
3) Buy a M.2 SATA SSD: $60+
4) This Silverstone adapter: $10!

The red LED indicates power while the green LED indicates SSD activity. Retro PC-loving me prefers them to be wired in reverse.

5.0 out of 5 stars Plug and play
By Joseph Lim on 31 October 2020
Previously I was using a NVME ssd and SATA ssd in separate enclosures, but they took up USB ports and I also think the transfer speeds were bottlenecked. This item seemed to be a good solution. After mounting the adapter and connecting the SATA cable, my PC was able to read the 2 drives. Very happy with this purchase, and it also comes with 2 thermal pads and a slot adapter for smaller PC cases. I am using a MSI B450M mobo.
