ASUS Hyper M.2 X16 PCIe 3.0 X4 Expansion Card V2 Supports 4 NVMe M.2 (2242/2260/2280/22110) Upto 128 Gbps for Intel VROC and AMD Ryzen Threadripper NVMe Raid

Product Information

This card enables one to add four M2 format disks to your desktop without having to go back to university.

Gbit/s) port, and exposes them through the same connector so both PCI Express and SATA storage devices may exist in the form of M. The second variable---how the card is keyed---just means the card connector must match the slot you'll be plugging it into. PCIe based drives in place, the adapter increases your storage capacity and gives your computer a significant speed boost, enhancing data transfer rates. module provides a 75-position edge connector; depending on the type of module, certain pin positions are removed to present one or more keying notches.

host or module to select which interfaces are to be supported, depending on the desired level of host support and the module type.

If bifuration is not supported any mb has the ability to use a more expensive PCIe to 2x or 4x or even 8x m. I populated the card with 3x NVMe drives, but only drive in the first slot is working the rest are not present in the system or BIOS. Note the that first two numbers refer to the width in 'mm' and the rest of the numbers refer to the length in 'mm' such that a 2242-sized M. If you want to use 4 SSDs on one adaptor you need to put it in a slot which gets 16 lanes - usually where you put your GPU. Given the vast number of SSDs the X21 can support, the AIC can't get all the power from the single expansion slot.

At a high level, primary advantages of NVMe over AHCI relate to NVMe's ability to exploit parallelism in host hardware and software, based on its design advantages that include data transfers with fewer stages, greater depth of command queues, and more efficient interrupt processing.
