Question 1

Does this enclosure support Windows 10 trim with a drive such as the Samsung 850 evo?

Accepted Answer

The Samsung EVO uses a different connector.  This is  an NGFF enclosure not NVME.  The connection type is convoluted and the only device i found that works is the Asus hyper m.2 x4 mini card.  Running samsung 950 on x79 with no issues.  Not running at fullspeed but still faster than sata.

Question 2

Does this work with PCIE M key m.2 SSD?

Accepted Answer

I am under the impression that M keyed drives don't support USB transfer anyway.

Question 3

I have purchased two different enclosures and found the contacts do not seat well. I have a Liteon CV1-8B256-HP. Any suggestions? Liteon has yet to reply to my email.

Accepted Answer

I have tried a couple of enclosures.  It seems the issue may be more with the M.2 drives than with the enclosure itself.  I have had the same issue when replaces drives in laptop. Normally you would insert the drive and if the hold down screw would go in, you would think that's good enough.  I have found that pushing the drive in firmly and once in position to put screw in, I have to put pressure on the drive forcing it firmly into seat while tightening hold down screw.  Hope that helps you out.

Question 4

Is this compatible with m.2 SATA III drives?

Accepted Answer

I used this with a m.2 SATA III drive when I was moving data from one computer to another.

Question 5

Is this compatible with the Samsung 960 PRO m.2 NVMe? I don't know what's an m key or b key

Accepted Answer

Not compatible. Works with an 850.

Question 6

Is this backwards compatible with USB-A 3.0 ?

Accepted Answer

Yes

Question 7

The picture depicts the usb 3.1 device as having a usb 3.0 micro-B connection.  Is this device properly listed?

Accepted Answer

In a way, yes. The enclosure side uses the Micro-B connector, while the other end of the cable is Type C. A Micro-B to Type A cable works as well, if you have one. Too bad both ends aren't Type C, that would have been neat.
