Right off the bat, problems with the machining of this device. The body is machined out of aluminum and cut in such a way as to provide a shelf/lip/rail for the circuit board to slide back and forth on using the thumb button. Nothing wrong with that part, the board it ships with fits fine. However, when I attached the M.2 drive to the board, it is supposed to fit in between the walls of the case, under those rails that the circuit board slides back and forth on. Herein lies the problem- the walls are not machined wide enough to comfortably accommodate this. So after I attached the drive to the board, and fit it into the case, the drive was sandwiched between the case walls, not allowing the circuit board to move in and out of the case with the thumb button. In fact, I had to pry it back out. I'm sure that the M2 drives are supposed to conform to an industry standard, but we are talking about G10 material that isn't going to be cut to 'machined' precise standards, which SilverStone should have taken into account when they were deciding on allowable tolerances related to this fit. They need to add another .005-.010"s to the case width. I was able to resolve this issue buy sanding down the sides of the M2 drive with some sandpaper- it didn't take much, just a few .001"s, and it was fine. However, I shouldn't have to take sandpaper to my drives to get them to work properly in this case.
Other than that, so far seems to function fine.
I looked at allot of other cards and decided on this one. I wasn't overly concerned with performance but I wanted reliability and ease of use. This card has met and exceeded those needs. The only thing I didn't like was the Win 7 x64 system didnt have the drivers build in and Windows Update didn't have them either. The card comes with all the needed drivers on a disc so i wasn't without.
Other than that its a great card. I would buy this again in a heartbeat.
By the way, I'm using this with a Samsung 960 pro on an Asus p8z77-v Pro -- yep, my i7 2600k still performs like a champ. Note that you won't be able to boot to this with older motherboards unless you mod your UEFI (google "boot nvme older motherboards" if you want to find some instructions.) It works perfectly for me after doing that, and I am in fact typing this on Windows 10 with no other drives in my system. I even went so far as to remove all of the drive bays in my computer and replace them with 240mm slow turning (silent) fans.
In the Windows 7 Device Manager, it shows "USB Input Device" with a flag and error "the device could not start." (This is DIFFERENT than the error you see when you are missing a driver.) I tried playing with IRQs, did a BIOS update, moved the card around, and even installed a firmware update from the manufacturer. Nothing solved it.
If you have USB 2.0 on your motherboard, this may work fine. If you already have USB 3.0, I think this may interfere. My motherboard is an MSI x99a gaming 7.
