Vszerda SATA 3.0 Splitter 1 to 5 Port JMB575

SKU CH-AFSB-Q5040

Expands one SATA port with port multiplier support into five SATA 3.0 connections using a JMB575 controller for compatible host controllers

  • Conductorcopper
  • Expands one SATA port to five drives using JMB575 Port Multiplier
  • Requires host port with Port Multiplier or Selector mode to function
  • Compatible with JMS582, JMB585, ASM1061, ASM1064, ASM1166 chipsets
  • Supports cascaded mode for up to five drives on a single host
  • Delivers SATA 6Gbps bandwidth across five independent channels

SATA 3.0 Port Multiplier Adapter

This Vszerda adapter uses a JMB575 controller to expand one SATA host port into five SATA 3.0 connections. It operates in Port Multiplier or Selector mode and complies with Port Multiplier Spec Revision 1.2 and Port Selector Spec Revision 1.0. The compact copper-conductor board connects five drives to a single cable.

Host Port Must Support Port Multiplier Mode

The single specification that decides compatibility is the host SATA port capability. Your motherboard or controller SATA port must expose Port Multiplier or Selector functionality, otherwise the adapter cannot work. Supported host chipsets include JMS582, JMB585, ASM1061, ASM1064 and ASM1166.

Thermals Noise and Power Draw

The passive adapter has no active cooling and produces no audible noise during operation. Power for the five downstream drives is supplied through the host SATA connection and the drives' own power cables. Normal use adds negligible thermal load to the host system.

Questions about this item

How many SATA drives can actually run at 6 Gbps from a single host port with the JMB575?

The JMB575 supports cascaded mode so up to 5 drives connect to one host port, each running at SATA 3.0 6 Gbps when the host uses Port Multiplier or Selector mode.

Which host controllers are confirmed to work with the Port Multiplier function required by this splitter?

Supported chipsets include JMS582, JMB585, ASM1061, ASM1064 and ASM1166; the host SATA port must be in Port Multiplier or Selector mode for the adapter to function.

What physical slot and cable arrangement does the adapter need to fit inside a case?

It plugs into a standard 22-pin SATA host connector and provides five 7-pin SATA data ports; the board measures 3.94 x 3.94 x 0.39 inches.
