Sixteen-Port SATA 3.0 Controller Card

This PCIe expansion card adds sixteen SATA 3.0 ports using JMB575 and ASM1064 chips, allowing simultaneous connection of up to sixteen SATA hard drives. It fits any available PCIe x1 slot and also works in x4, x8 or x16 slots. The card supports Windows 8, Windows 10, Linux and macOS for broad system compatibility.

SATA 3.0 6 Gbit/s Bandwidth Limit

Each of the sixteen ports delivers a maximum theoretical throughput of 6 Gbit/s as defined by the SATA 3.0 specification. When all ports are active at once the aggregate demand can exceed the bandwidth of a single PCIe x1 lane, so sustained performance across every drive simultaneously may be constrained by the host slot width.

Upgrade from Fewer Port Controllers

The card replaces controllers that offer fewer SATA connections, enabling a single-slot upgrade to sixteen drives instead of multiple cards. The jump is worthwhile when a workstation or server requires high-density storage expansion beyond the port count of the existing motherboard or add-in card.

Questions about this item

Should I choose the version with 16 SATA 3.0 ports or a smaller card?

The card provides 16 SATA 3.0 ports so you can connect up to 16 drives at once; pick this model only if you need that many simultaneous connections.

What does the 6 Gbit/s headline speed mean once the card is installed?

Each of the 16 SATA 3.0 ports can transfer up to 6 Gbit/s, so every attached drive can run at the full SATA 3.0 rate rather than sharing a single lane.

Which PCIe slot standard does the card use and what does it cap in practice?

It fits a PCI Express x1 slot and also works in x4, x8 or x16 slots, so the host interface caps at x1 electrical bandwidth regardless of the physical slot used.
