1. Icy Box IB-PCI208-HS
Space for performance
Do you need free storage space and want to move your data at a high transfer rate at the same time? Then use this PCIe expansion card and place it conveniently and perfectly integrated in a free PCIe slot on your PC. With PCIe 4.0 and up to 64 Gbit/s, your data will travel super-fast.
Ignite the data turbo
If you want to give your M.2 SSD a turbo boost, then connect it to the super-fast PCIe 4.0 expansion card. This enables data transfer speeds of up to 64 Gbit/s - waiting is a thing of the past.
Always stays cool
The SSD always stays cool, even under the highest loads. The large, solid aluminium heat sink in an innovative cooling fin design ensures sufficient heat dissipation to keep the SSD stable and powerful. In addition, the expansion card is supplied with thermal pads that are attached to the M.2 card.
Highly customisable
The perfect carrier for your M.2 SSD is called IB-PCI208-HS. In the variants with a full or half-profile slot bracket, it can be perfectly integrated into a free slot in your PC. The built-in M.2 NVMe is connected via an M-key socket.

2. ASUS Hyper M.2 X16 Card

The card is designed for the latest generation of NVMe drives and includes an improved power supply with up to 14 W per drive, as well as a large heatsink and an active fan to ensure that the drives remain cool for optimal performance.

3. Delock PCI Express card
This PCI Express card from Delock expands your PC with two M.2 NGFF slots. You can connect up to two M.2 NGFF modules in the 22110, 2280, 2260, 2242, or 2230 format to the card. Depending on whether you have SATA or USB-based modules, you will need to connect either the SATA ports or the USB port to your motherboard.

4. Axagon PCEM2-N
With the PCEM2-N, AXAGON offers an internal adapter that connects an NVMe M.2 SSD to the PC via a PCI-Express slot. This is particularly useful when the motherboard does not have a suitable M.2 slot or when those slots are already occupied. The adapter allows the use of single-sided and double-sided M.2 SSDs in x16, x8, and x4 PCIe 3.0 slots.
The PCI-Express bus powers the PCEM2-N directly, eliminating the need for an external power source. Thermal pads and copper ventilation openings help dissipate the heat generated by the M.2 SSDs under load. Two LED indicators provide information on the connection status and data transfer activity.
