We've seen plenty of PCIe x16 add-on cards that put out four M.2 NVMe slots, but noting quite like this. The Icy Dock ExpressSlot MB204MP-B lets you swap in and out four M.2 NVMe drives. They can even be hot-swappable, provided your host platform and software support it. The technological part of the card is simple—there is no bridge chip, it relies on the host's PCIe lane bifurcation to turn a x16 slot to four M.2 slots with x4 wiring, each. The four drives have their own link/activity LED. A 50 mm lateral blower fan ventilates the four drives. Much of the innovation is in the way the drives can be installed and swapped or even hot-swapped. Intel VROC or AMD RAID technologies on platforms such as Xeon W "Sapphire Rapids" and Ryzen Threadripper 7000-series, should also lend RAID features.
