Vszerda

Vszerda PCIe to M.2 Adapter M-Key + B-Key

SKU CH-DZ40-KKYYR

Adds an M-key and B-key M.2 slot to a PCIe expansion slot for SATA or NVMe SSDs

  • Supports both M-key and B-key M.2 SSDs
  • Connects via PCIe for faster NVMe drive speeds
  • Backward compatible with SATA-based M.2 drives
  • Single card adds high-speed storage to desktop PCs

Dual M-Key and B-Key M.2 support

This PCIe add-on card accepts both M-key and B-key M.2 modules, letting you install NVMe or SATA SSDs without a native M.2 slot on the motherboard. It is aimed at system builders and upgraders who want to add fast storage to an older platform or a board that lacks the required connector. The card plugs into a standard PCIe slot and requires no extra drivers for basic operation.

Sustained transfer depends on drive and slot

Under continuous read or write workloads the adapter itself adds negligible latency, so sustained speeds are dictated by the installed SSD and the PCIe generation and lane count of the host slot. A SATA M.2 drive will remain limited to the SATA 6 Gbps ceiling, while an NVMe drive can only reach its rated throughput if the slot provides sufficient PCIe lanes and generation. Builders needing multiple simultaneous high-speed drives or RAID arrays should verify platform lane allocation before purchase.

Highlights

  • Supports both M-key and B-key M.2 SSDs
  • Connects via PCIe for faster NVMe drive speeds
  • Backward compatible with SATA-based M.2 drives
  • Single card adds high-speed storage to desktop PCs

Questions about this item

How much extra heat does this adapter add when an SSD runs continuously?

The passive board has no fan or heatsink; heat output depends entirely on the installed drive, so sustained loads will warm the slot area but the adapter itself adds no active cooling.

Which drive types fit the M-key and B-key slots on this card?

The M-key slot accepts NVMe drives; the B-key slot accepts SATA drives. Each key is physically keyed to prevent inserting the wrong type.
