Design Features
The attention to detail that has gone into creating our SAS to SATA product line ensures a robust electrical and protocol bridge between the SAS (Serial Attached SCSI) host interfaces and all manner of SATA (Serial ATA) storage. The foundation of this series is the high-density SAS 29-pin (SFF-8482) male connector, which provides reliable connections to SAS backplanes or HBAs. Available in different versions, the product line ranges from standalone 7-pin SATA data and 15-pin SATA power connectors to 22-pin SATA connectors (straight and 90-degree), and low-profile adapters that can use the LP4 (Molex) adapter to provide the driving voltage (5V/12V) needed for SATA drives. Instead, each product is fitted with gold-plated contacts (15 μ) for optimal signal integrity and includes latching mechanisms on SAS connectors to prevent detachment. Cables feature foil and braid shielding, protected by rugged PVC jackets.
Application
These components play a vital role in connecting SATA hard disks and SSDs to enterprise mass storage systems based on SAS architecture. The market for SATA SSDs is largely focused on hybrid storage arrays (with both SAS and SATA drives) & for JBOD (Just a Bunch of Disks), where, in either case, a pool of high-capacity, low-cost SATA drives is managed by a SAS host bus adapter (HBA) or RAID controller. They are important in data centre hardware upgrades or migrations, where new SAS controllers must be attached to existing SATA drive inventories. These products, along with their value in test and diagnostic laboratories to confirm SATA drive compatibility and performance with SAS test equipment. Both the 90-degree and LP4 power models are designed specifically for cramped server chassis only, with little room to place a conventional SATA power connector; they have been tested in dense 1U/2U servers, custom NAS/DVR builds, and using SATA SSDs as boot drives for SAS servers.
Quality & Testing
SATA cables and adapters are tested for quality assurance. This process includes 100% continuity and functional testing to confirm that the pin mapping between the SAS 29-pin interface and target SATA connector(s) is intact. The passive protocol translation capability is verified by a critical test that demonstrates the device’s ability to accurately expose a SATA drive to a SAS host controller. The effectiveness of the latching mechanism is confirmed by batch testing of sample SAS connectors through thousands of mating cycles (to ensure mechanical durability). Cable versions are subjected to pull tests at terminations and flex-life tests. The compliance of all raw materials and final products with CE and RoHS standards is verified.
Customisation Options (OEM/ODM Services)
For B2B clients with customised projects, we provide a full service from OEM to ODM. Customisation options include building cables to exact length (usually between 0.3m and 1.0m) and creating unique SATA connector angles other than our standard 90-degree angle (e.g., left-angle, down-angle). Connector housings can be custom-branded via laser etching or labels. We specialise in custom packages for high-volume projects. Limited engineering configurations and their respective design variants can be accomplished with a formal prototyping and sample-approval workflow: as an example, our team will be capable of developing the capability to support unique application needs (integrating different power connector types for connectivity (SATA power instead of LP4), or differing source connector types for SAS.
How to Install the SAS to SATA?
Power Off & Check Ports: Make sure the server or storage system is completely powered down. Find the SAS 29-pin (SFF-8482) port on your HBA, RAID card, or drive backplane.
Select Correct Model: Depending on the connector of your target SATA drive and the power source you use (do you need an LP4 or a separate SATA power connection), you must select the proper cable/adapter.
- SAS 29-pin male connector: Insert the SAS 29-pin male connector into the appropriate port. The connector has keying, so it can only be oriented one way. Press until you hear the latching mechanism click—an audible click —then it will be secure.
Connect SATA End & Power:
– For 7+15-pin cable: Attach the 7-pin data and 15-pin power connectors to the drive.
– 22-pin cable: Directly connect the single 22-pin connector to the drive.
— For Adapters: Connect the SATA 7-pin data end of your drive. The drive needs an additional SATA power cable for the power supply.
– For LP4 Power models: Here, you will attach the 7-pin data end of the SATA to your drive, and insert the LP4 (Molex) into an available 4-pin peripheral power cable from your power supply unit (PSU).
Cabling, ensuring all wires are cleanly routed without sharp bends or pinches, and with no impact on airflow. Check that adapters click into their ports securely.
Power On & Verify: Switch on the system. Step 2 – Use a utility (such as LSIutil or MegaRAID) to access the HBA or RAID controller configuration. Alternatively, enter the server BIOS and check if SATA is properly detected on the SAS controller.
User Experience
- Data centre technicians and system integrators alike routinely share with us that our SAS to SATA products function reliably as plug-and-play compatible solutions, solving a common interoperability problem. This organisational structure is further reflected in the offerings, with separate models that differ in power and form factor, such as the LP4/90-degree ends, thereby reducing installation errors. Users noted that this approach makes it much easier to know exactly what you are working with when comparing options.
- Build quality is often praised, particularly for the tightness of the SAS latch and the connector’s overall robustness, making it a good candidate for production environments. The LP4 power cable variants are frequently touted as advantageous for use in test benches and systems with limited SATA power ports.
- These products do indeed work as described, enabling SATA drives/systems to be kept on SAS controllers seamlessly without complication. Generally speaking, the consensus puts these sorts of products as must-have professional tools for building and maintaining a flexible price-optimised storage system.

It attaches a server’s or RAID controller’s SAS (Serial Attached SCSI) port to a SATA (Serial ATA) hard drive or SSD, creating visibility so that the SAS host can see and control SATA storage devices. This feature is critical for integrating low-cost SATA into enterprise SAS storage systems.
The SAS 29-pin connector or SFF-8482 (small form-factor) is a widely adopted standard interface used on SAS host bus adapters (HBAs), RAID cards, and some specific drive backplanes. It carries data, and sometimes power signals. This connector is the common host-side interface for our cables.
SAS 29-Pin to SATA 7+15-Pin Cable if you need to connect to a standard SATA drive, but have available separate SATA power cable available. Choose the SAS 29-Pin to SATA 22-Pin Cable if you are connecting to hardware (e.g., a drive or certain backplanes) that utilises the combined 22-pin internal SATA data and power cable.
The SAS 29-Pin to SATA Cable with LP4 Power has an extra 4-pin peripheral (Molex) connector. That allows you to power the SATA drive directly from a standard peripheral cable in your power supply unit (PSU), eliminating the need for a separate SATA power cable. This is particularly useful when the SATA power ports are limited.
If the physical space in front and behind your SATA drive in the server chassis has been very limited, you can use a 90-degree SAS to SATA Adapter. The right-angle design helps prevent the cable from bending too sharply or damaging a drive’s port, addressing clearance challenges within dense 1U/2U servers.
No. These cables and adapters are made specifically for one-way use from a SAS host (controller) to a SATA target (drive). They cannot be used to connect a SAS drive with a SATA motherboard port.
The speed of data transfer will proceed at the rate of the slowest device in your chain. The maximum speed on these cables when connecting to a SATA III drive would be limited to 6 Gbps since SATA III (6 Gbps) is slower than SAS 3.0 (12 Gbps). The cable itself be higher SAS protocol aware from the host side.
The cables are passive components themselves. Hot-plug support depends on your SAS HBA/RAID controller hardware, OS drivers, and the backplane (if you have one). You’ll want to ensure that your system’s documentation is followed to verify hot-plug capability. Use the operating system’s “Safely Remove Hardware” or drive ejection feature if one is available.

The continuous integration of low-cost, high-capacity SATA drives into an enterprise environment built on premier performance-oriented SAS components is a prevalent and vital need in today’s enterprise storage landscape. Choosing the right SAS to SATA cable isn’t just about buying a cable that connects something. This guide serves as a professional guideline to help B2B buyers, system integrators, and IT managers evaluate the fundamentals to ensure the cable is best suited for their application, helping them secure their hardware and business processes.
Narrow Down Your Target Drive’s Connector Type Exactly
A SAS to SATA cable’s primary purpose is to connect a SAS host interface, generally found on an HBA or backplane as a 29-pin port, to a SATA drive. Step one: You need to know what HDD or SSD your target SATA has. Do you need a cable that ends in a standard 7-pin SATA data connector (which requires a separate SATA power cable), or a combined 22-pin SATA connector that supplies both data and power? Maybe you require a small adapter for a tight area. You have the SAS 29 Pin to 7+15-pin giving you maximum flexibility, or the 22-pin cable for a streamlined connection. Connecting the cable to the wrong end makes it unusable.
Confirm Power Delivery Specifications and Form Factor Constraints
A SATA drive needs data and power. You will have to decide on the wiring of the 5V/12V power. Does your system have SATA power connectors available, or would an integrated solution be preferable? Cables with LP4 (Molex) power connectors are the best option for systems without SATA power; they will pull directly from the PSU. Moreover, evaluate the available physical space in your chassis. A standard connector may not fit behind a drive in 1U/2U dense servers. This is where a 90-degree SAS to SATA adapter or cable with at least one 90-degree end on the SATA side is required to alleviate clearance issues and prevent strain on the cables while ensuring proper attachment.
Verification of Supported Application Protocols
The primary job of these is to convert SAS to SATA, but just check that the cable supports the speeds you need. The drive should support SAS 3.0 (12Gbps) on the host side and SATA III (6Gbps) on the drive side; the link will be at a slower SATA speed. Think about your application: are you constructing a hybrid storage array, migrating data, or building a test bench? If your topology requires a Mini SAS to SATA style cable (SFF-8087/8088 connectors) for hard-to-acquire devices, seemingly suggested on page [insert link here] with full 29-pin cable specification, it simply wouldn’t work in backplanes or specific enclosures. Understanding the ecosystem is key. If you are looking for more compatible storage, check out our SAS cable category.
Assess Build Quality and Manufacturer Reliability
The cable is a key component of your data pipeline. Seek long-term reliability features: a SAS connector with a secure latching mechanism to avoid disconnection, and gold-plated contacts for the best signal integrity, along with high-grade shielding. As a legitimate manufacturer with experience in the field, working with a partner such as Bespokecable, an ISO 9001:2015 factory manufacturer for more than 20 years, provides peace of mind that the materials are made to high standards, meet regulations (CE, RoHS), and deliver functional performance. In B2B procurement, services such as bulk pricing, OEM Customisation, and fast sample programs are equally important to the product itself. Investing in a high-quality cable from a reliable source reduces risk and enhances system stability. You can also browse our full range of SATA cables to round out your storage setup.
