SMUGDESK 16-Port SATA III PCIe 3.0 X1 Controller Card ASM1064 + JMB575 Chip SATA Expansion Add On Card

SKU CH-H20F-AFDB7

Adds sixteen SATA ports through a single PCIe 3.0 X1 slot using ASM1064 and JMB575 controllers for 24/7 Chia mining or NAS storage

  • 16 SATA III ports at 6Gbps each for massive storage arrays
  • ASM1064 and JMB575 chipset delivers 24/7 mining stability
  • PCIe 3.0 X1 fits X1 through X16 slots without extra power
  • Boots in AHCI mode on Windows Linux FreeNAS Unraid
  • Hot-swap NCQ SMART support with full and low-profile brackets included

16-Port SATA III Expansion Card

This PCIe 3.0 X1 controller card adds 16 independent SATA III ports to a system, each capable of 6Gbps bandwidth. It is built around ASM1064 and JMB575 chips and targets Chia mining farms, NAS builders and server storage upgrades that need many drives from a single slot.

Sustained 24/7 Operation

An integrated heatsink keeps the dual-controller layout stable during continuous mining or NAS workloads. The card draws all power from the PCIe slot itself, so no external connectors are required, and it supports hot-swap, NCQ and SMART for drive health monitoring without downtime.

PCIe 3.0 X1 Bandwidth Limit

All 16 ports share a single PCIe 3.0 X1 link, so aggregate throughput cannot exceed that lane’s ceiling when many drives are active simultaneously. The card fits X1, X4, X8 or X16 slots and includes both full-height and low-profile brackets, but buyers who need more total bandwidth than one lane provides should look elsewhere.

Questions about this item

Does the ASM1064 + JMB575 controller card run hot or draw extra power during 24/7 Chia farming?

The integrated heatsink keeps the 16-port SATA controller stable under continuous mining loads, and the PCIe 3.0 X1 slot supplies all necessary power without external connectors.

What must my motherboard provide for the 16 SATA III ports to function?

A single PCIe 3.0 X1, X4, X8 or X16 slot is sufficient; no additional power cables or proprietary headers are required.

Will my older SATA 3Gbps hard drives work at full speed alongside this 6Gbps expansion card?

Each of the 16 ports negotiates independently, so legacy 3Gbps drives operate at their native rate while newer 6Gbps drives reach full bandwidth.
