I bought this card about six months ago to the SATA SSD in a Dell Precision 5810 workstation using a 1 terabyte Samsung 970 Evo Plus as the boot drive. It was easy to setup and the performance has been great. I work in technology for a living and have been buying parts like this from StarTech for 10 plus years and I've never been disappointed with their products or their support. If I were, I have no doubt they would take care of it.
Before you install any kind of PCI Express card to use an NVMe SSD as a boot drive, do the research to make sure your systems supports it. Otherwise, that's on you for not "reading the directions".

We’re sorry to hear our PEX4M2E1 is not working properly in your setup. This card is a pass-through adapter that allows an NVMe SSD to connect directly to the PCI Express bus of a computer which is why there are no drivers needed for the card. To boot to an SSD connected to this adapter you would need to make sure your computer can support booting to NVMe SSDs. If you require assistance we would be happy to help look into this for you.

Install is simple, and the box included the necessary screws. Used a Samsung 850 EVO m.2.
Win10 picked it up right away. This thing is plenty fast on the older ASUS motherboard I am using (son's computer). He is plenty happy at the speed difference over his old SATA drive, and even over the old SATA SSD we had in there. Though I can't say that I had time to do any detailed measurements, he was talking about it all day, telling his friends how much faster the computer was, etc. and the only change was adding this adapter with the m.2 drive mounted on it.
I just ordered another one for myself and am going to tinker around with Linux and an HP Mini Server (low-profile bracket was in the adapter box too!).
I received this product in exchange for an unbiased review.
Windows SBS2011 and Server 2012 unable to see NVMe as a secondary drive with this controller. Provided steps are useless and complicated. Both controllers are going back. Startech should put more effort to assist customers with this product instead of suggesting to follow 20 steps to get it working.

Thank you for your feedback on PEX4M2E1. We apologize that is hasn't worked for you yet. Since NVMe drives are natively supported by Windows Server 2012, however, SBS 2011 may require a driver to be installed to enable support since it is based on Server 2008 R2 and lacks native support.

I bought this adapter couple of months ago and my experience with this: easy to use in Windows 7 x64 with an 6 years old mainboard. Thanks to this I have a great performance SSD now in my system.
Even though this claims it has native os support it would not install my Windows 7 Ultimate x64 box. With no drivers listed on the website or a disc in the box it came in to try and install it manually this is a waste of my time and money. Normally Startech makes good products. if you're using Windows 7 best that you pass this one up.

Microsoft has ended support for Windows 7 and has stopped hosting the hotfix. To align with them, we have decided to remove the FAQ and hyperlink as well. Instead of using the hotfix, we recommend our customers upgrade to an operating system with native support for PCIe SSDs (NVMe). We have created a note in our Technical Specifications of PEX4M2E1 to reflect this.
If you have any questions please feel free to contact us.

Thank you for your feedback on our PEX4M2E1.
This card does have native support in any operating system that supports M.2 NVMe drives. Windows 7 does not natively support this drive type and needs a patch from Microsoft in order to use M.2 NVMe drives.
Please refer to our FAQ on this topic for more information: https://www.startech.com/faq/NVMe_drive_Windows_7_hotfix#PEX4M2E1
If you still have issues with this card please do not hesitate to contact us for support. One of our Technical Advisors would be happy to help!
