Vszerda 5-Port SATA III PCIe x4 Controller JMB585 Low Profile

SKU CH-JY84-3JKMH

Adds five SATA 6 Gb/s ports via a PCIe 3.1 x4 slot with a JMB585 controller for up to 1700 MB/s throughput

  • Add five SATA drives via a single PCIe x4 slot
  • Up to 1700 MB/s throughput with JMB585 chipset
  • Works immediately with no driver installation needed
  • Supports port multiplier for extra drive connections
  • PCIe 3.1 and SATA 6 Gb/s compliant design

Five SATA III ports over PCIe x4

This controller adds five SATA 6 Gb/s ports to a desktop through a single PCI Express 3.1 x4 slot. The JMB585 chipset delivers up to 1700 MB/s of aggregate bandwidth for connected SSDs and HDDs. A low-profile bracket is included for small-form-factor chassis. Installation is plug-and-play with no extra software required.

Suits builders expanding internal storage

Ideal for users who need more SATA connectors than the motherboard provides and who do not require hardware RAID. The card operates in non-RAID mode and supports port multipliers outside of a RAID configuration. Not suited for buyers who need on-board hardware RAID functionality. Not suited for systems that lack a free PCI Express x4 slot.

JMB585 chipset with PCIe 3.1 x4 interface

The SI-PEX40139 controller complies with the PCI Express 3.1 specification and connects to the host through a four-lane slot. This lane width determines the 1700 MB/s throughput ceiling shared across all five ports. Verify that the platform offers an available x4 slot before purchase.

Questions about this item

Do I need a free PCIe x4 slot to install this JMB585 controller card?

Yes, the card plugs into any available PCIe x4 slot and provides five SATA ports for drives.

Will my existing SATA SSDs and HDDs work with the JMB585 chipset?

The JMB585 chipset supports standard SATA solid state drives and hard drives without RAID configuration.

How can I verify the card reaches the stated 1700 MB/s throughput after setup?

Run a disk benchmark on a connected drive; sustained sequential reads near 1700 MB/s confirm the PCIe 3.1 x4 link is operating correctly.
