ASRock is looking to launch a PCIe expansion card for all of your M.2 needs. Should you find your current motherboard is already full to the gills with M.2 SSDs, ASRock's Hyper Quad M.2 PCIe expansion card will allow you to increase M.2 vacancy by up to four additional slots (there's an on-off toggle for you to move in the PCB to select the active M.2 SSDs). The card uses the PCIe 4.0 x16 interface to sufficiently feed the four M.2 SSDs (which typically use the PCIe 4x NVMe protocol) with data.

This is a top notch expansion card design, featuring an aluminium cover and a 50 mm fan to cool down all those SSDs' controllers. The cover features 4x 110 mm thermal pads which align with the M.2 mounts on the PCB, thus allowing the aluminium cover to serve as a veritable heatsink and improve operating temperatures. The expansion card is fed by a single 6-pin power connector, and there is an activity LED for quality of life improvements. No word on pricing just yet.
