The JMS579 is built on a highly integrated architecture that minimizes external component requirements, making it ideal for cost-sensitive and compact storage designs.
Its job is translation. It takes the SATA signal used by internal hard drives and SSDs and translates it into a USB signal that your computer can understand. jmicron jms579

True (10Gbps) requires different chips (often the JMicron JMS583, which is used for NVMe enclosures).
The JMS579 is technically a controller. If you remember the confusing naming conventions, "USB 3.1 Gen 1" is actually just USB 3.0 (5Gbps).
