ASM1061 PCI-E to SATA 3.0 Expansion Card: Add Dual SATA and eSATA Ports to Your Desktop

When your desktop motherboard runs out of SATA ports for additional storage drives, this PCI-E expansion card provides a straightforward solution. It installs into a standard PCI Express slot and uses the proven ASM1061 controller chip to add two high-speed 6 Gb/s SATA 3.0 ports and two eSATA ports to your system. A key functional feature is the ability to boot your operating system directly from a hard drive connected to this card, and it supports the connection of both traditional hard disk drives (HDDs) and modern solid-state drives (SSDs), as well as optical drives like DVD or Blu-ray burners. The card is designed for compatibility, requiring no additional driver installation on Windows 7 or Apple macOS systems, allowing for a plug-and-play experience on these platforms.

Features and Construction

This expansion card is built around a single, core component that defines its capabilities: the ASM1061 Serial ATA host controller chip. This chip handles the protocol conversion between the PCI Express bus and the SATA/eSATA interfaces, managing data transfer for the connected storage devices.

Material and Build

The card's functionality centres on the ASM1061 integrated circuit. This chip is responsible for all interface management, enabling the card to provide its stated ports. The construction includes physical jumper blocks which are a critical part of the user interface; these jumpers allow you to manually select and configure the active ports (SATA3 or eSATA) according to your needs, offering a level of hardware-level control over the card's connectivity options.

Size and Practical Fit

The source information specifies that the card is available in multiple model variants, labelled with the style options A, B, C, D, and E. Crucially, it states that these different models have different physical sizes. Therefore, if precise dimensions for fitting into a specific computer case are required, you should confirm the exact measurements of the particular model variant you are selecting, as a universal size is not provided.

Uses and Placement

This card is designed for desktop computer systems where internal expansion is the primary goal. It solves the common problem of limited onboard SATA ports, which can restrict storage upgrades.

Event or Professional Use

For users requiring high-capacity or specialised storage setups—such as video editors needing fast SSD arrays, data archivists adding multiple high-capacity hard drives, or systems operating optical disc libraries—this card reliably adds the necessary ports. The support for system booting means it can be integral to a workstation's primary storage configuration, not just secondary data pools. The driver-free compatibility with Apple systems makes it a viable option for expanding storage on certain Mac models fitted with standard PCI-E slots.

Everyday Home Use

For the home desktop user, this card enables straightforward storage expansion. It allows for the addition of a large-capacity hard drive for media libraries, a fast SSD for games and applications, or the reconnection of an internal optical drive in newer cases that may lack support. The eSATA ports offer the potential for fast external storage solutions if your computer case has an eSATA pass-through bay.

Benefits and Buying Value

The value of this expansion card lies in its specific function and compatibility, providing a dedicated solution for a common desktop PC limitation.

Reuse and Low Maintenance

As a simple hardware add-on with no required software drivers for supported operating systems, maintenance is minimal. The card can be moved between compatible desktop systems as needed. Its functionality is tied to the widespread SATA standard, ensuring it will remain useful for connecting a wide range of storage devices for the foreseeable lifespan of the SATA interface.

Why Choose This Product

This card is a match for users who need more SATA or eSATA ports and value the specific capabilities confirmed by the source text: boot drive support, SSD and optical drive compatibility, and driver-free operation on Windows 7 and Apple systems. The presence of the ASM1061 chip is a known quantity in the market for reliable SATA expansion. When selecting, the key consideration is the model variant (A-E), as the physical size differs, ensuring you choose one that fits your computer's available PCI-E slot space.
