PCIe AHCI Mass Storage

Former Member

Hi

anyone had any luck with any PCIe AHCI card?

we are using Plextor SSD, and it seems to have problems on desktop PCs, we see the same.

Is the problem related to Plextor, or is the problem some generic issue with Xilinx PCIe?

    no, no issues- the AHCI M2 SSD can be used with Xilinx PCIe root, no quirks patches or custom drivers needed. It just works.

    Can you report on the SSD read/write performance via PCIe?

    Thanks.
