Black adapter cable linking an M.2 slot to an EDSFF connector, 50 cm long with a 15-pin SATA power plug

LetLinkSo

LetLinkSo LLS-CB-MTED-01 M.2 to EDSFF adapter 1.6 ft 50 cm 32 GT/s 15P SATA power

SKU CH-Q4RV-RFJNA

Converts an idle M.2 slot to an EDSFF interface with PCIe 5.0 x4 speed and 15-pin SATA power

  • Rated speed32 GT/s (per lane)
  • Connector count2
  • Connector details1 x M.2 to 1 x EDSFF
  • Connector genderMale to Male
  • Conductor typeCopper Conductor
  • Product typeM.2 to EDSFF

Connector Type Left Exit

  • Converts idle M.2 slots to EDSFF without system replacement
  • Full PCIe 5.0 x4 128Gbps speed with 32 GT/s lanes
  • Works with E1.S E1.L E3.S E3.L SSDs in 1U 2U servers
  • 15P SATA power prevents throttling under full load
  • 6 feet 50 cm length enables quick single or batch SSD swaps

M.2 to EDSFF adapter for servers

This LetLinkSo adapter converts an unused M.2 slot into a standard EDSFF interface supporting E1.S, E1.L, E3.S and E3.L solid-state drives. It operates at PCIe 5.0 x4 speed (128 Gbps) with backward compatibility to PCIe 4.0 and 3.0. The 1.6-foot (50 cm) cable uses a copper conductor and terminates in male-to-male connectors.

15-pin SATA power and left-exit cable

A 15-pin SATA power connector supplies the EDSFF device directly, preventing throttling or instability under full load. The left-exit cable routing eases installation inside 1U and 2U chassis where space is tight. Arrows on the drive and adapter must align during insertion; reversing the connection can damage the drive.

Suits admins expanding storage without board swaps

Ideal for data-centre operators adding EDSFF capacity to existing servers or workstations that have spare M.2 slots. Not suited for builders who need a second adapter in the same slot, for systems lacking a 15-pin SATA power lead, or for installations where the left-exit cable cannot be routed cleanly.

Questions about this item

How often will the 15P SATA power connector need replacement under continuous operation?

The 15P SATA power connector is a passive copper interface with no moving parts and no defined service interval; it lasts the life of the adapter unless physically damaged.

What is the first limit reached when the adapter runs at 32 GT/s per lane all day?

The first limit is the PCIe 5.0 x4 bandwidth ceiling of 128 Gbps; the copper conductors and 15P SATA power delivery are rated for that sustained throughput.

How much heat does the 50 cm cable generate when carrying 128 Gbps continuously?

The 50 cm copper cable adds negligible heat; all active thermal load comes from the EDSFF SSD itself, not the adapter.
