Key benefits throughput multidrive connection: native support for five SATA devices at 6 Gbps lets you connect multiple hard drives or SSDs through a single bridge for fast data transfer and aggregation. Broad host compatibility: USB 3.1 Gen 2 (Revision 1.0) host support provides up to 10 Gbps link capability to modern PCs and workstations (backward compatible with USB 3.0/2.0). Reliable protocol handling: builtin USB BulkOnly Transport (BOT) compliance ensures consistent, widely supported data transfers with common host software and OS drivers. Testability and diagnostics: supports BIST (BuiltIn Self Test) and loopback mode to simplify manufacturing validation, field diagnostics, and firmware development. Compatibility and standards Main control chips: JMB575 + JMS580 (as specified). SATA side: complies with Serial ATA 6 Gbps Electrical Specification 3.2, compatible with SATA SSDs and HDDs at up to 6 Gbps per port. USB side: complies with USB 3.1 Specification Revision 1.0 and USB BOT Specification for host communication. Technical features Five SATA 6 Gbps ports: supports up to five independent SATA device connections. USB 3.1 Gen 2 interface: standard USB 3.1 host connectivity with broad OS support; backwards compatible with earlier USB standards. Diagnostics modes: BIST and loopback support for automated selftest, signal verification, and easier troubleshooting during production or field service. Controller architecture: dualchip solution using JMB575 and JMS580 for SATA aggregation and USB bridging (exact firmware and performance depend on implementation). Performance and practicality Designed for multidrive throughput scenarios where several drives must be accessed or migrated through a single host connection. Provides deterministic, standardscompliant behavior for integration into enclosures, docks, duplicators, or storage expansion devices. Typical applications Multibay external storage enclosures or docking stations that require five SATA ports and USB 3.1 host connectivity. Drive duplicators or migration tools needing reliable multidrive access and builtin test/diagnostic modes. NAS expansion modules, workstationlevel storage adapters, or service benches where multiple drives must be connected to a single host for backup, imaging, or diagnostics. Notes and implementation guidance For exact physical dimensions, enclosure material options, and thermal or power requirements, consult the product datasheet or manufacturer specifications for the JMB575 + JMS580 implementation you are using. Performance depends on host capabilities, drive performance, USB cable quality, and chassis thermal design. BIST and loopback modes can assist in validating signal integrity and functional operation during integration.
