## Summary description

QNAP QDA-SA3 is an internal interface adapter that converts a SAS host connection to SATA output, supporting up to 6 Gbit/s transfer rates. Designed for installation inside servers or NAS enclosures, it enables connection of SATA drives to SAS-capable backplanes. The adapter is available in black and grey and suits upgrades, drive migrations and system expansions.

## Long description

The QNAP QDA-SA3 internal SATA interface adapter converts a SAS host connection to SATA output, enabling a SATA 2.5-inch 6 Gbit/s drive to be used in SAS 12 Gbit/s/6 Gbit/s drive bays. Intended for installation inside servers or NAS enclosures, this adapter is designed for use with QNAP dual-controller all-flash Enterprise ZFS NAS systems and allows adding cost-effective SATA drives to expand storage capacity while taking advantage of the host SAS infrastructure.
Advantages
The adapter provides a simple, low-profile solution for connecting SATA 6 Gbit/s drives to SAS-capable backplanes without modifying the chassis. It supports the sharing of SAS dual-port benefits—such as redundancy and improved fault tolerance—when installed in compatible dual-controller NAS systems. Its compact internal form factor and two-color finish (black/grey) make it suitable for standard 2.5-inch drive trays in enterprise enclosures.
Suitable for
 Installing SATA 6 Gbit/s 2.5-inch drives into SAS 12 Gbit/s/6 Gbit/s drive bays
 Expanding storage capacity in dual-controller all-flash Enterprise ZFS NAS systems
 Drive migrations from SAS to SATA where the backplane accepts SATA devices via an adapter
 Server or NAS upgrades that require internal adapters for mixed-drive environments
When it may not be suitable
This adapter does not convert protocol limitations beyond physical connectivity; it enables SATA drives to connect to a SAS host but does not change drive performance characteristics beyond the SATA device’s rated speed. It is designed specifically for internal use in compatible 2.5-inch drive trays and is not suitable for external docking, hot-swap enclosures that require different interfaces, or systems that do not support SATA devices on their SAS backplane.
Key specifications
 Host interface: SAS
 Output interface: SATA
 Supported drive form factor: 2.5-inch SATA drives (6 Gbit/s)
 Transfer rate: up to 6 Gbit/s for SATA output
 Compatibility focus: dual-controller all-flash Enterprise ZFS NAS (tray-based 2.5-inch bays)
 Product colour: Black, Grey
 Intended use: internal installation
 Weight: 0.02 kg
How to use
Install the QDA-SA3 adapter into the 2.5-inch disk tray of a compatible NAS or server following the enclosure’s procedure for inserting drives and adapters. Slide a SATA 2.5-inch drive into the adapter and secure it in the drive tray, then insert the tray into the SAS-capable bay. Ensure the host system is powered down or follow hot-swap procedures recommended by the NAS manufacturer. After physical installation, verify drive detection in the storage system’s management interface and confirm the drive is recognized and available for configuration.
What to consider before purchase
 Confirm your NAS or server backplane supports SATA devices connected via an adapter
 Verify compatibility with your specific drive tray model and enclosure (tray size and mounting points)
 Ensure your storage system firmware and controllers support mixing SATA drives into the SAS environment
 Check whether dual-port SAS redundancy features will be available to the SATA drive in your configuration
Usage recommendations
Use the QDA-SA3 in compatible dual-controller Enterprise ZFS NAS models for storage expansion with SATA drives, follow vendor guidance for tray installation and hot-swap procedures, and validate drive recognition and operational status via the NAS management console after installation.
