Dilinker U.2 to PCIe Adapter - x4 PCIe - for 2.5" U.2 NVMe SSD - SFF-8639 PCIe Adapter - U.2 SSD - PCIe SSD - U.2 Drive(PEX4SFF8639)

Works great! Was previously using a U2 to M.2 cable adapter and it had random issues the system detecting it on bootup. A restart of the system would often bring it back. With this adapter instead it been able to 100% of the time be detected on bootup.

Habs mir für meine 7,68TB SSD geholt und es läuft einwandfrei. Klare Kaufempfehlung

In diesen Adapter steckt man eine U.2 SSD, welche dann als Karte in einen freien PCIe Slot gesteckt wird. U.2 SSDs sind NVMe SSDs im 2.5 Zoll Format und sind im herkömmlichen Konsumer-Segment eigentlich nicht vertreten.Keine weiteren Kabel sind nötig, Daten und Stromversorgung laufen alle per PCIe.Wie man am Bild sehen kann, erreicht der Adapter auch Geschwindigkeiten über PCIe3. Natürlich muss dafür die SSD auch schnell genug sein.Fazit: Nach 3 Monaten im Betrieb gab es keinerlei Probleme und keine Leistungseinbuße. Booten ist auch möglich.

I used two of these cards to install two used e-bay Toshiba 800 GB U.2 NVMe drives into a Dell R720xd server. The adapters themselves are great, no problems fitting either the drives or into the PCI slots. After all, they are just simple cards with nothing but a U.2 socket, some holes for screws to anchor the drive (the screws that come with the cards are too short, thankfully I have a lot of hardware from old dead computers laying about), and a single very small surface-mount device (probably a resistor), and traces to connect the socket to the card edges.On first startup I was a bit disappointed when my new to me NVMe drives didn't show up in bios or the Dell hardware inventory manager program that runs at cold boot. I thought I wasted my money because after all Dell says in their documentation this particular server does not support NVMe on the PCIe buss.But I kept playing with them and finally figured it out. The drives have their own BIOS/Management software that loads as the very last thing after all of the firmware BIOS, iDRAC, RAID card, etc setup programs run and just before the OS boots. I just configure boot mode to UEFI and both drives came right up. Ubuntu on install recognized them and I set them up as software Raid 1 and it is running lightning fast. The gui is ready for sign-on in about 30 seconds when the OS finally starts booting, which is quick indeed compared to the 2 or 3 minutes it used to take booting from the RAID array.A bit of an overkill for a home-lab VM host machine but it is my toy, it was fun, and anytime I add hardware and it works (especially when Dell says it won't) is a reward in itself. So all told about $160 on ebay for the two NVMe 800 GB drives and about $60 for these two cards and I've got a nice hot-rod server!

I got an ebay intel p4500 and must have tried 6 different cards with my Pcie2.0 mobo. This was the only card that would let the computer boot into windows. All the others would hang on the POST screen. If you have an older computer this is the one you need.
