edit:  okay, I re-read what you said and yes, these won&#x27;t support M.2 drives, if I understand what&#x27;s going on here, and it&#x27;s possible I still don&#x27;t.  (I have yet to buy any non-sata SSD, though I will soon be making experimental purchases.)<p>I was talking about these:<p><a href="http:&#x2F;&#x2F;www.supermicro.com&#x2F;products&#x2F;nfo&#x2F;NVMe.cfm" rel="nofollow">http:&#x2F;&#x2F;www.supermicro.com&#x2F;products&#x2F;nfo&#x2F;NVMe.cfm</a><p>Note, though, it looks like if you are willing to pay for a U.2 connected drive, you can get &#x27;em with the giant heatsinks you want:<p><a href="http:&#x2F;&#x2F;www.pcper.com&#x2F;news&#x2F;Storage&#x2F;Connector-Formerly-Known-SFF-8639-Now-Called-U2" rel="nofollow">http:&#x2F;&#x2F;www.pcper.com&#x2F;news&#x2F;Storage&#x2F;Connector-Formerly-Known-S...</a><p>further edit:<p><a href="http:&#x2F;&#x2F;www.intel.com&#x2F;content&#x2F;dam&#x2F;www&#x2F;public&#x2F;us&#x2F;en&#x2F;documents&#x2F;product-specifications&#x2F;ssd-750-spec.pdf" rel="nofollow">http:&#x2F;&#x2F;www.intel.com&#x2F;content&#x2F;dam&#x2F;www&#x2F;public&#x2F;us&#x2F;en&#x2F;documents&#x2F;...</a><p>available;   not super cheap, but I&#x27;m not sure you&#x27;d want the super cheap consumer grade stuff in a server, anyhow.<p>further edit:<p>but I object to the idea of putting SSDs on PCI-e cards for any but disposable &quot;cloud&quot; type servers (unless they are massively more reliable than any that I&#x27;ve seen, which I don&#x27;t think is the case here.) just because with a U.2 connected hard drive in a U.2 backplane, I can swap a bad drive like I would swap a bad sata drive;  an alert goes off and I head off to the co-lo as soon as convenient and I can swap the drive without disturbing users, whereas with a low-profile PCI-e card, I&#x27;ve pretty much gotta shut down the server, de-rack it, then make the swap, which causes downtime that must be scheduled, even if I have enough redundancy that there isn&#x27;t any data loss.
