4-Port B Key M.2 SATA PCIe 3.0 x1 Expansion Card with ASMedia ASM1064 Chip, PCI-E NGFF SSD Riser Adapter Card Specially for Chia Plot Mining, Support 2230/2242/2260/2280 SATA M.2 Drives

This PCIe 3.0 x1 to 4-port M.2 B Key SATA expansion riser card adopts reliable ASMedia ASM1064 dedicated 4-channel SATA control chip, designed primarily for Chia cryptocurrency plot mining to greatly expand storage capacity on mining rigs with limited motherboard SATA/M.2 ports.

The card carries four independent M.2 B Key slots, only compatible with SATA protocol NGFF M.2 solid-state drives; it cannot identify M Key / B+M Key NVMe PCIe SSDs. All four slots support universal M.2 dimensions including 2230, 2242, 2260 and 2280, so you can mix different capacity SATA M.2 drives for plotting space expansion.

Built on PCIe Gen3 x1 bus, the adapter delivers stable total bandwidth for parallel multi-disk plot writing and reading without frequent disconnection or drive drop issues during long-time mining operation. It features plug-and-play design with zero complicated driver setup, fully compatible with all mainstream mining operating systems: Windows, Linux, Ubuntu, NAS and VMware ESXi.

Equipped with a standard full-height PCI metal bracket, this expansion card can be stacked multiple pieces in one mining chassis to build high-density plot storage arrays. The PCB uses gold-plated M.2 contacts and anti-interference circuit layout to reduce signal attenuation and avoid disk recognition failures under 24/7 non-stop mining workloads.
