DELOCK internal M.2 to Mini-SAS adapter card 64260, M.2 host, Mini-SAS output, JMicron JMB585, black, LED

DELOCK internal M.2 to Mini‑SAS adapter card 64260 converts an M.2 (Key B+M) host interface into a Mini‑SAS output with four SATA ports, allowing connection of SATA SSDs, hard drives and optical drives. The card is based on the JMicron JMB585 chipset, fits inside a system as an internal adapter and includes access and power LEDs. It is designed for use with Windows 10/11 and Linux (Kernel 6.5) and comes in black.

Advantages

The adapter supports SATA transfer rates up to 6 Gb/s and includes features such as Native Command Queuing (NCQ), S.M.A.R.T. monitoring, TRIM support for SSDs and DevSleep power management. It supports hot-swap operation and can be used as a boot device. The internal form factor and LED indicators simplify installation and operation inside desktop or server systems.

Suitable for

• Adding multiple SATA SSDs or HDDs to a system with an M.2 (Key B+M) slot
• Systems requiring hot-swap-capable internal storage
• Environments where S.M.A.R.T. monitoring and TRIM support are needed
• Desktop PCs and servers running Windows 10/11 or Linux (Kernel 6.5)

When it may not be suitable

The adapter requires an available M.2 slot with Key B+M and a compatible motherboard BIOS to boot from Mini‑SAS-connected drives; systems without the appropriate M.2 interface or BIOS support may not be able to use all functions. It is an internal card and is not designed for external use without additional enclosures or cabling.

Key specifications

• Host interface: M.2 (Key B+M)
• Output interface: Mini‑SAS providing four SATA ports
• Chipset: JMicron JMB585
• Maximum data transfer rate: up to 6 Gb/s per SATA port
• Supported features: NCQ, S.M.A.R.T., TRIM, DevSleep, hot swap, bootable
• Indicator LEDs: access and power
• Form factor: internal adapter, colour: black
• Supported operating systems: Windows 10/11 and Linux (Kernel 6.5)

How to use

Install the adapter into an available M.2 Key B+M slot on the motherboard following standard anti-static precautions. Connect the Mini‑SAS output to a compatible backplane or SATA device interface using the appropriate cable. Ensure the system BIOS recognises the adapter if you intend to boot from connected drives, then configure storage devices in the operating system and enable features such as TRIM where applicable.

What to consider before purchase

• Confirm the motherboard has an M.2 Key B+M slot and supports an internal M.2 adapter for SATA expansion
• Verify BIOS/UEFI support if you plan to boot from drives connected via the adapter
• Check cable and backplane compatibility for the Mini‑SAS output and the required internal connections
• Ensure your operating system version is compatible (Windows 10/11 or Linux with Kernel 6.5)

Recommendations

For best performance, use SATA SSDs that support TRIM and enable NCQ where supported by the drive and operating system; verify cables and connectors are firmly seated and monitor S.M.A.R.T. status regularly to maintain drive health.
