I have a Samsung PM983 2.5" SSD drive but I have never seen a connector like this.

Would like to use it but unsure of what I need to connect.

Can anyone assist?

2.5 inch SSD

It's a U.2 interface, formerly known as SFF-8639.

U.2 can be used for SATA Express, SAS, or Enterprise PCIe. As far as I can see, the 2.5" U.2 version of the Samsung PM983 is only available as PCIe. In this case, it'd be possible to adapt to M.2 (NVMe only) or a PCIe x4 card.

    I believe you meant to say "should". I've tried to look around, and there doesn't seem to be any *reliable* information about converting from U.2 to M.2 (but there's lots to go from M.2 to U.2). – Ismael Miguel Sep 13 '19 at 16:49

    @IsmaelMiguel SU doesn't do shopping recommendations, but [they do exist](https://www.amazon.com/CableCreation-SFF-8639-SFF-8643-Compatible-Mainboard/dp/B07D8RBY7C/). – Jason Sep 13 '19 at 17:33
  • :/ my google-fu must be rusty. But that is an interesting find. – Ismael Miguel Sep 13 '19 at 21:43
  • @IsmaelMiguel EDIT: Was gonna say I will PM you the card I recommend but forgot you can't PM on here...I had much better luck getting a card that converted it directly to PCIe instead of that cable + adapter combo. Unfortunately, all the companies you will come across are pretty obscure/slightly shady. – Scott Simontis Sep 16 '19 at 22:10
  • @ScottSimontis I was actually looking for examples to compliment the answer, not to buy for myself. I can't afford that type of tech :( – Ismael Miguel Sep 16 '19 at 22:21

Per this table on the Samsung website, all PM983 drives use the PCIe Gen3 x4 interface which I believe is a data centre blade interface. I don't believe you can plug this into a desktop PC with a regular SATA style cable.

    Correct, essentially a M.2 NVME conector in a different form-factor. Samsung also makes these same drives in the regular M.2 form-factor. – Tonny Sep 12 '19 at 14:20

    Is this also called U.2? – Eddie Dunn Sep 12 '19 at 15:14

    @EddieDunn Yes it is. https://rog.asus.com/articles/hands-on/easy-guide-to-ssds-sata-msata-m-2-and-u-2/ – spikey_richie Sep 12 '19 at 15:31

    It’s strange that this Samsung table is so useless, the formfactor does not specify the m.2 size/height and the interface column does not mention u.2 – eckes Sep 13 '19 at 07:42

SAS (serial attached SCSI) in a form factor partially compatible with SATA

(SFF-8482)

https://en.wikipedia.org/wiki/Serial_Attached_SCSI

p.s. it is partially compatible w/ SATA in a sense that a SAS host can run a SATA disk, but not the other way round.
