UGREEN US217 30796 0.5m SATA III Data Cable
A 0.5m straight-to-straight internal 7-pin SATA data cable for connecting a motherboard or controller SATA port to one SATA HDD, SSD or optical drive. Metal latch clips help retain both keyed connectors inside a compatible desktop chassis.
Product overview
Overview
UGREEN US217 30796 is an internal point-to-point SATA cable, not a USB adapter. One 7-pin plug connects to a SATA controller or motherboard port and the other connects to a SATA drive’s 7-pin data receptacle. Both connectors are straight, so case clearance must be checked at both ends.
SATA III supports a 6Gbps theoretical signaling rate, with backward negotiation to SATA II and SATA I. The exact title and SATA III classification support 6Gbps; an isolated 5Gbps line in the current body copy is not retained because it does not match the SATA interface specification or exact model presentation.
The flat black construction is shown with tinned-copper conductors, insulation, aluminum-foil shielding and grounding elements inside a PVC jacket. Shielding and latch retention support a stable link, but real drive speed still depends on the controller, media, firmware, queue depth and workload.
Verified highlights
Key features
- Exact format: 0.5m internal SATA data cable with one straight 7-pin plug at each end.
- SATA III link: up to 6Gbps theoretical, backward compatible with SATA II and SATA I at lower rates.
- Metal latches: retention clips engage compatible latching SATA receptacles and release when the clip is pressed.
- Data-only wiring: no 15-pin power contacts; the drive’s power supply cable remains mandatory.
- Point-to-point connection: one controller port to one SATA storage or optical drive.
- Flat flexible jacket: routes along a case while broad bends reduce strain on sockets.
- Shielded conductor stack: exact artwork identifies PVC, aluminum foil, tinned-copper conductor and ground structure.
- No conversion electronics: the cable carries native SATA and does not convert to USB, M.2 or eSATA.
Know the exact connector roles
SATA data, power and connector map
A 2.5/3.5-inch SATA drive has adjacent data and power sections. This cable fits only the narrower 7-pin data section.
- Controller-side 7-pin plug: connects to an internal SATA data port on the motherboard, host bus adapter or supported controller.
- Drive-side 7-pin plug: connects to the narrow SATA data receptacle on a HDD, SSD or SATA optical drive.
- L-shaped key: controls orientation. Align it visually and never force or rock the plug.
- Metal latch: presses down for removal; pulling without releasing can damage a compatible latching socket.
- Separate 15-pin power: comes from the computer power supply and is not included in this cable.
- 0.5m route: allows moderate internal routing; coil excess loosely without sharp folds or fan obstruction.
- Native SATA path: carries data without USB or PCIe protocol conversion and uses the controller’s negotiated SATA generation.
Where it makes sense
Use scenarios
Use the cable to add or replace one internal SATA data link where 0.5m reach and straight connectors fit the case layout.
- Connect a 2.5-inch SATA SSD to a desktop motherboard while providing its separate SATA power lead.
- Connect a 3.5-inch SATA HDD to an available controller port for storage, backup or media libraries.
- Connect a SATA DVD/Blu-ray optical drive inside a desktop when the controller, OS and separate power supply support it.
- Replace a damaged, loose or intermittently detected SATA data cable during systematic storage troubleshooting.
- Route a drive to an add-in SATA controller or supported backplane whose internal port and case clearance match the straight plug.
- Use in a workstation build where latch retention is preferred and the 0.5m length can be routed without obstructing fans.
A dependable first connection
Setup and usability guidance
Work inside a powered-down computer and identify both the SATA data port and the separate power connector before routing.
- Shut down the operating system, switch off and unplug the computer, then discharge residual power according to the case/motherboard guidance.
- Use antistatic precautions and locate an available internal SATA controller port plus a compatible 2.5/3.5-inch SATA drive or optical drive.
- Check that a separate 15-pin SATA power connector from the power supply reaches the drive.
- Align one 7-pin plug’s L-shaped key with the controller port and insert it straight until fully seated and latched.
- Route the 0.5m cable with broad bends, clear of fans, sharp edges and hot components, then attach the other end to the drive data socket.
- Connect the separate SATA power lead, secure the drive in its bay and close the case before restoring mains power.
- Enter firmware or the operating-system disk utility to verify detection. Do not initialise or format a drive that contains needed data.
- For removal, power down again, press the metal latch and withdraw the connector straight without pulling on the cable.
Match the whole chain
Compatible devices and systems
Compatibility depends on native internal SATA data sockets, suitable case geometry and a separate power path for the drive.
- Desktop motherboards and SATA host adapters with an internal 7-pin SATA data receptacle.
- 2.5-inch SATA HDDs and SATA SSDs with standard data and power edge connectors.
- 3.5-inch SATA HDDs with standard data and separate 15-pin power connection.
- Internal SATA optical drives when supported by the controller, operating system and application.
- SATA III, SATA II and SATA I devices at the mutually negotiated interface generation.
- Cases with enough straight-connector clearance and a route of approximately 0.5m.
- Latching and non-latching SATA sockets, provided the plug fits normally; retention behavior can differ by receptacle.
Capabilities
What this product does
- Carries native SATA data between one controller port and one compatible drive.
- Supports the SATA III 6Gbps theoretical signaling ceiling with backward negotiation.
- Provides straight connectors at both ends for conventional internal routing.
- Uses metal latch clips to help retain the cable in compatible SATA receptacles.
- Connects SATA HDDs, SSDs or optical drives when their separate power and controller support are present.
- Replaces an existing 7-pin SATA data lead without adding driver or conversion electronics.
Clear boundaries
What this product does not do
- It does not supply drive power; a separate 15-pin SATA power cable is required.
- It does not connect USB, USB-C, eSATA, IDE/PATA, SAS, mSATA or M.2 drives.
- It does not convert protocols, add a controller port or make a SATA drive work in a PCIe-only socket.
- It does not provide RAID; RAID depends on the controller, firmware and software.
- It does not guarantee that a drive is bootable; BIOS/UEFI, controller mode and OS installation determine boot support.
- It does not guarantee hot plug/hot removal. Power down before normal internal connection changes.
- It does not make a failed drive, unsupported filesystem or disabled motherboard port operational.
Good practice
What to do
- Power down, unplug and use antistatic handling before working inside the computer.
- Align the L-shaped key and press/release the metal latch correctly instead of pulling on the jacket.
- Provide the drive’s separate SATA power lead and secure the drive mechanically in its bay.
- Route with broad bends and keep the cable clear of fans, heat sinks, case edges and closing panels.
- Label controller and drive ends in systems with many similar cables, and retain a known-good cable for diagnosis.
- Back up important data before changing controller mode, partitions, RAID settings or filesystem structures.
Avoid these mistakes
What not to do
- Do not mistake the narrow 7-pin data plug for the wider 15-pin SATA power connector.
- Do not force the key, pull without pressing the latch or lever sideways against a motherboard socket.
- Do not route the cable through a fan blade, trap it under a graphics card or crush it with the side panel.
- Do not connect or disconnect inside a powered system unless every component explicitly supports a managed hot-plug procedure.
- Do not daisy-chain SATA data cables; one controller port connects point-to-point to one drive.
- Do not expect more than the negotiated controller/drive generation or treat 6Gbps signaling as a guaranteed file-transfer result.
Important safety and performance notes
Warnings and limitations
Internal connectors and exposed components can be damaged by static, wrong orientation or live insertion. Treat the cable change as computer service work.
- A loose or partially seated data connector can cause resets, CRC errors, missing drives or filesystem damage during writes.
- Press the metal latch before removal. Excess force can crack the plastic tongue or pull a motherboard port from the PCB.
- SATA power is separate; never improvise power by altering this data cable or using an unverified adapter.
- Hot-plug support depends on the SATA controller, BIOS mode, operating system, drive and physical power sequence; it is not promised here.
- Changing AHCI/RAID/controller modes can prevent an existing OS from booting and may alter array behavior. Follow motherboard guidance.
- The 6Gbps SATA III value is theoretical. HDD media rate, SSD controller, cache state and workload usually determine observed speed.
- Stop using a cable with cut insulation, deformed latches, burnt contacts or connection errors that change when the cable moves.
Keep it working and solve common issues
Care, troubleshooting and buying checklist
Separate cable integrity from power, controller configuration and drive health by changing one component at a time.
- Drive not detected: power down, reseat data and separate power leads, try another SATA port and verify the controller is enabled.
- Intermittent resets: replace the data cable with a known-good lead, inspect the latch/socket and check the power connector.
- CRC errors: review SMART UltraDMA CRC counts where available, reroute away from interference and replace a suspect cable.
- Lower link rate: confirm the controller and drive support SATA III; a SATA II device correctly negotiates lower.
- Visible in firmware only: inspect OS storage drivers, disk state, partitions, filesystem and mount settings.
- System no longer boots: restore the correct boot drive, port order and AHCI/RAID firmware mode; the cable alone cannot configure boot.
- Buying check: verify 7-pin internal SATA data sockets, separate power, straight-plug clearance and a 0.5m route.
