TXB127 SFF8639 Interface 2-port Solid State Drive (SSD) Adapter Board to PCLEX8 to 2 U.2 Expansion Card •The TXB127 is an internal PCIe (1x SFF-8643 72-pin) PCI Express x8 bifurcation riser card. PCI Express bifurcation means splitting a PCI Express bus into smaller multiple slots. For example,an x8 PCI-Express port can be bifurcated into two x4 PCI-Express ports. This can be configured from the motherboard BIOS if you want to split an existing channel. This adapter is designed to connect high-performance 2.5" NVMe U.2 (SFF-8639) SSDs via an SFF-8643 cable. U.2 SSDs can be loaded into backplanes with SFF-8643 connectors interfacing with the adapter,allowing U.2 SSDs to be used like drive cartridges. •High-Performance Storage Connectivity: Features two internal NVMe (SFF-8643) connections for optimal storage performance •Mini SAS HD (SFF-8643) Clock Pin Output: Supports Intel-defined Mini SAS HD clock pin output for enhanced compatibility •Dual NVMe Device Support: Accommodates two physical NVMe devices for increased storage capacity and flexibility •Driver-Free Installation: This converter requires no drivers,ensuring a hassle-free setup •PCIe Compatibility: Compatible with PCIe 3.0 and PCIe 2.0 motherboards,providing versatile integration options •Low-Profile Bracket Support: Includes support for low-profile and half-height mounting brackets,fitting a variety of systems Specification: •Model: TXB127 •Interface type: PCIE •Applicable models: conventional desktop computers •Expansion interface: SFF-8639 •Supported systems: for Windows2000/xp/server2003/xp64-bit/Vista/win/linux/DOS/MAC •Installation conditions: the personal computer has one or more available standard PCIE slots •Note: The motherboard with a CPU and BIOS must support bifurcation to ensure the PCIe x8 link width can be split into two x4 NVMe •SSD • link widths. If not supported,the TXB127 riser card will only support a single NVMe device with a PCIe x4 link width. Package included: •1 x Adapter Card
