SABRENT 4-Drive NVMe SSD to PCIe 4.0 X 16 Adapter Card with Active Cooling [EC-P4BF]

More Storage: Add up to four high-performance NVMe SSDs to a system with a single adapter in a physical x16 PCIe slot with the Quad NVMe SSD to PCIe 4.0 x16 Card (EC-P4BF). The system requires the PCIe bifurcation (lane splitting) function to add more than one SSD with the full 16 lanes required for 3 or 4 drives.
PCIe 4.0 Compliant: Supports even the fastest PCIe 4.0 SSDs but also works with older and newer generation SSDs at up to 4.0 speeds. Works in older 3.0/2.0 systems that have PCIe bifurcation support. Compatible with NVMe SSDs in the M.2 2230/2242/2260/2280 form factors for your convenience.
Built Cool: Designed with quality aluminum for physical stability and top-notch cooling. Thermal padding is included to ensure the best cooling interface for your SSDs. Optional active cooling (fan) via a rear-positioned switch for high-performance environments. Your drives won’t throttle in here.
RAID Capable, Flexible Management: The card is plug and play with no drivers required. Supports Intel VROC and AMD Ryzen NVMe RAID with their respective limitations. Drives may be operated individually or in software and UEFI RAID which includes Windows Storage Spaces.
Supported By Sabrent: This card requires M.2 M key NVMe SSDs and UEFI PCIe bifurcation support to work properly. The destination PCIe slot must be x16 in physical length. Please visit the manufacturer website for more information and contact our technical support team for assistance.

FAQ:

Q: How many pins does a PCIe x16 slot have?

A: PCIe x16 has 82 pins and is 89 mm long. Regardless of the size or number of pins, the key notch is always at the eleventh pin. The pin itself gets longer with larger sizes, which provides some flexibility. PCIe cards can fit into slots larger than themselves (and their own, obviously) but not in smaller ones.

Q: Can I plug PCI X1 to x16?

A: @Scandalist Technically yes you can put a x1 in an x16 slot, the extra lanes just won’t be used. However in real life, on some computers it doesn’t work because the manufacterer has made alterations. Rule of thumb tends to be you can put a ‘smaller’ PCIe card into a larger slot – so a x1 will fit in an x16.

Q: What is PCI Express x16 mean?

A: PCI Express x16 means that there are 16 communication channels in the interface between the motherboard and video card. If your motherboard has a PCIx x16 slot, then you can get a PCIx x16 card (best) or any number of channels down to PCIx x1.

Q: What is a PCI Express x16 port?

A: The PCI-E x16 ports, with a theoretical maximum of around 15GBps on the 3.0 revision, are used for almost all modern graphics cards designed by NVIDIA and AMD. Most discrete graphics cards use a full PCI-E x16 slot. RELATED: What Is the M.2 Expansion Slot, and How Can I Use It?
