Frequently Asked Questions

Q: What is the difference between the 5-Port NGFF and 5-Port NVMe versions of this M.2 to SATA riser card?

A: The 5-Port NGFF version uses the M.2 NGFF (SATA-based) interface with the JMB575 chip and requires your motherboard to support Port Multiplier (PM) functionality. The 5-Port NVMe version uses the M.2 M-Key PCIe 3.0 ×2 interface with the JMB585 chip, offering an upstream bandwidth of up to 16Gbps — making it a better choice for systems that don't support PM or need higher throughput.

Q: Is this M.2 to SATA adapter card compatible with Windows 11 and Linux?

A: Yes! All three variants of this riser card (5-Port NGFF, 5-Port NVMe, and 6-Port NVMe) are compatible with macOS, Windows (including Windows 10/11), and Linux operating systems. Most systems will detect the card automatically with built-in drivers.

Q: Can I use this riser card with an M.2 NVMe SSD slot, or does my motherboard need a specific type of M.2 slot?

A: The NVMe variants of this card require an M.2 M-Key slot that supports PCIe (NVMe), not a SATA-only M.2 slot. The NGFF variant requires a SATA-based M.2 M-Key or B+M Key slot. Always check your motherboard manual to confirm which M.2 slot types are available before purchasing.

Q: How many SATA drives can I connect to this expansion card?

A: Depending on the variant you choose, you can connect either 5 or 6 SATA drives simultaneously. Each SATA port supports up to 6Gbps (SATA 3.0 speed), making it ideal for HDDs, SSDs, and optical drives.
