Key Features: A Single Chip to Meet Dual-Drive Expansion Needs
The ASM1156 is a highly integrated single-chip solution that combines a USB 3.2 Gen-I controller with a dual SATA controller in a single package. Its main features are as follows:
Dual SATA Channel Support: The chip provides one USB 3.2 Gen-I port and two SATA device ports. The USB PHY supports data transfer rates of up to 5 Gbps, whilst the SATA PHY can reach speeds of up to 6 Gbps, in compliance with the Serial ATA Revision 3.2 specification. This means users can connect two SATA hard drives or SSDs simultaneously via a single USB interface, enabling capacity expansion or data mirroring.
HydraTek proprietary technology: The ASM1156 integrates ASMedia’s proprietary HydraTek technology, supporting hardware-level JBOD (Junction of Bays) mode and cloning functions, whilst ensuring high-efficiency operation under low-power conditions. The cloning function allows the contents of one hard drive to be copied in full to another without connecting to a PC, making it suitable for data backup and bulk deployment scenarios.
Storage Management Capabilities: The chip supports SATA NCQ commands, high-capacity drives exceeding 2TB, staggered spin-up, and independent power management for each hard drive. The built-in SMART monitoring function reads hard drive health status in real time, providing underlying support for the reliability of storage devices.
Integration and Packaging: The ASM1156 incorporates an 8-bit microprocessor and programmeable RAM/ROM, supporting SPI NVRAM, I²C master/slave modes and multiple GPIOs (for LED indicators and storage power control), as well as fan control and hard drive insertion detection. The chip is housed in an 8mm × 8mm 64-pin QFN package and complies with RoHS environmental standards.
Typical Applications
The ASM1156 has a very clear purpose: USB-to-dual-SATA bridging and expansion. In actual products, this chip has been widely adopted in dual-bay hard drive docks from brands such as Delock, Inateck, Youyue and Greenconn. Typical applications include:
Dual-bay hard drive docks/cloning docks: Support 2.5-inch and 3.5-inch SATA HDDs/SSDs, enabling offline cloning or data erasure at the touch of a button. Taking the Delock 64187 as an example, this dock utilises the ASM1156 chip, supports USB 5 Gbps data transfer, and is equipped with dedicated cloning and erasure buttons, allowing data copying to be completed without connecting to a PC.
External storage docks: These expand laptops or desktop computers with dual SATA storage channels, maintaining a stable transfer rate of 5 Gbps. The Inateck FD2002 hard drive dock is also equipped with the ASM1156 chip and supports the UASP transfer protocol; when paired with a host controller that supports UASP, performance is improved by up to 70 per cent compared to traditional USB 3.0.
Data Archiving and Backup Device: Utilises the HydraTek cloning function to perform data mirroring operations independently of the host computer.
Industrial and Embedded Storage: Suitable for data acquisition and edge storage nodes requiring dual-drive redundancy or rapid drive replacement.
