SMUGDESK PH44+PH56 PCIe 4.0 X16 20-Port SATA NVMe RAID Adapter
PCIe 4.0 X16 card adds 20 SATA 3.0 ports plus M.2 NVMe RAID via JMB585 chip
- 20 SATA ports expand storage capacity from one PCIe 4.0 x16 slot
- JMB585 chip delivers stable 6Gbps SATA 3.0 throughput per port
- Combined PH44 and PH56 modules enable M.2 NVMe RAID arrays
- Hot-swap support allows drive changes without system downtime
- Robust circuit design maintains reliable operation during 24/7 server use
20-Port SATA Expansion
The SMUGDESK PH44+PH56 adapter converts a single PCIe 4.0 X16 slot into twenty SATA 3.0 connections running at 6Gbps. It combines the PH44 and PH56 modules under a JMB585 controller and adds support for M.2 NVMe RAID arrays. Hot-swap capability allows drive changes without powering down the system.
Servers and NAS Builders
This card targets administrators who need dense, reliable SATA connectivity for hard drives or SSDs in 24/7 environments. The 20-port count and hardware RAID support suit multi-drive storage pools. Builders who require fewer than sixteen ports or who lack a full-length PCIe 4.0 X16 slot should consider a smaller controller.
PCIe 4.0 X16 Slot Required
The adapter occupies one PCIe 4.0 X16 slot and will not function in a shorter physical slot or an older PCIe generation without bandwidth loss. Verify that the motherboard or riser provides a genuine X16 mechanical and electrical connection before purchase.

Questions about this item
How does the JMB585 chip handle heat and power draw when all 20 SATA ports run continuously?
The JMB585 controller is built for 24/7 operation and maintains steady 6Gbps SATA 3.0 throughput across every port. Its robust circuit design resists interference and keeps performance consistent during sustained workloads.
Which motherboard slot and drive types are required to use the 20 SATA ports and the M.2 NVMe RAID function?
You need a free PCIe 4.0 X16 slot. The card accepts standard SATA HDDs or SSDs on the 20 ports and an M.2 NVMe drive for RAID array setup.
Will the PH44+PH56 card work alongside an older PCIe 3.0 motherboard and existing SATA 3Gbps drives?
The card installs in a PCIe 4.0 X16 slot and negotiates the link speed automatically. Connected SATA drives operate at their native 3Gbps or 6Gbps rate, so legacy drives remain fully usable.
