Maybe a Necessity if You Have a USB-C on Front Panel Header because no USB 3.2 GEN1 connector on motherboard. The PCI-E 1X to USB 3.2 GEN1 5Gbps 20pin Front Panel Header allows you to connect the USB-C front panel header to your PCI-E 1X slot

Easy install, works as expected.

Used this to expand the number of drives in a smallish Ubuntu home server. Still testing, but seems flawless so far and transparent to the user - just more drives available. All I did was power down, plug it in the PCIe 3.0 slot, attach a couple drives, and power up. Drives were recognized immediately and accessible like all the others. They claim max throughput of 277MB/s but so far both drives tested at 500 MB/s+ the same as when plugged into the mobo ports. I assume the limited speed might occur if multiple drives were accessed at once. Since it's a server and I'm using this to add SSDs, i doubt I will ever notice any slow downs. Bonus: the 6 provided SATA cables have locking connectors and are of a reasonable length.

- The heat sink plate is WELL CONSTRUCTED and nice and thick! Make sure you mount your M.2 NVMe drives and then place the heat sink adhesive on the drives and then mount and screw the plate in place. - Note: the board has a +12V fan connector on it that is not used in this variant. Riitop sells another that is a fan-based model were a fan (in place of the plate) would normally mount. - The kit comes with a decent screwdriver you need to install the heat sink plate. I have sooo many screwdrivers now because I have ordered similar kits.

I have a P67 board with pcie 2.0 from an i5- 2500 non k cpu and a Toshiba XG5 256GB NVMe drive, this drive has stated speeds of 2700 MB/s read and 1050 MB/s write. Because my system is only pcie 2.0 i loose half of the theoretical speed so I get 1500 MB/s read and the stated 1050 MB/s write. In order for the card to be seen by the OS your bios needs to absolutely be UEFI, otherwise it will NOT be detected, i had to flash my mobo bios to latest bios which was uefi and then inserted the required NVMe files in the bios. In order to get pcie 3.0 on the 1155 socket you need to have 3000 series i5 and i7, lower cpus from 3000 series are only pcie 2.0! The card also has 4 green LEDs that blink nicely when the drive is being accessed. In theory , after inserting the NVMe modules in the bios it should be bootable, but for me it doesn't work, it is detected in bios as PATA SS device, but no dice. For older systems that are not UEFI natively, only Samsung 950pro is bootable in LEGACY mode! I am upgrading my rig to H170 + i3-7100 so no more issues.

Doing a rebuild using a 25yr old motherboard with PCI/ISA bus. This PCI card is recognized by Win98 but drivers are not included with the product, are not all present on the Win98CD (original or Second Update) and links in the paperwork sent with the card no longer work (not really surprised after 25 years). Fortunately drivers are available at www.philscomputerlab.com/windows-98-usb-storage-driver.html in the file nusb36e.exe. Run the EXE under Win98 before installing the card. All Win98 drivers will load automatically upon powerup after card installation. Now I can use USB keys to move files rather than floppy disk or CD. Having fun playing Doom 2.
