SATA cable QOLTEC 50582 — internal data cable for SATA drives

QOLTEC 50582 is an internal eSATA III data cable designed to connect SATA hard drives, SSDs and optical drives to motherboards or SATA controllers. With a 0.5 m length and eSATA III M to eSATA III M connectors, the cable supports standard point-to-point data transfer between storage devices and the system, suitable for PC assembly, upgrades and drive replacement where an eSATA interface is required.

Advantages

The cable implements the eSATA III standard to provide up to 6 Gbps theoretical transfer speed, ensuring compatibility with modern SATA III storage devices. Its compact 0.5 m length reduces internal cable clutter and helps maintain neat airflow inside the case. The matched male connectors at both ends offer a secure point-to-point connection for external SATA-capable enclosures or backplane ports that use eSATA wiring.

Suitable for

• Connecting internal or external SATA III hard drives and SSDs to motherboard or SATA controller ports
• PC assembly and system upgrades where a short eSATA link is needed
• Replacing damaged or worn eSATA cables in desktops or storage enclosures
• Use with eSATA-capable docking stations, enclosures or dedicated backplanes

Key specifications

• Standard: eSATA (SATA III)
• Connector type: eSATA M to eSATA M
• Maximum interface rate: up to 6 Gbps (SATA III theoretical rate)
• Cable length: 0.5 m
• Usage: point-to-point data connection for SATA devices

How to use

Power off the system before connecting or disconnecting storage devices. Insert one eSATA M connector into the motherboard or controller eSATA port and the other into the drive enclosure or device eSATA port, ensuring firm seating without forcing the connector. After connection, power on the system and verify that the BIOS or operating system detects the drive. For hot-plug capable controllers, follow the controller and OS procedures for safe removal and insertion.

Usage recommendations

Use this 0.5 m eSATA III cable for short, direct connections where minimal cable length improves airflow and reduces signal interference. Avoid sharp bends, kinks and exposure to high temperatures. If your device or motherboard uses standard internal SATA (not eSATA) connectors, confirm compatibility or use an appropriate adapter.
