Frequently Asked Questions

Before You Buy

There are no known incompatibilities between this hard drive adapter and any SSDs or motherboards; however, certain SSDs and motherboards may be incompatible with each other. Before you use an SSD and motherboard together, you should check with the SSD and motherboard manufacturers for any potential compatibility issues.

For example, the Intel 750 series SSD may not work as expected when you use it with certain motherboards. For more information, refer to the Intel documentation for the 750 series located here: www.intel.com/content/www/us/en/support/solid-state-drives/consumer-ssds/000005729.html.

You can use this hard drive adapter to boot an operating system from; however, depending on the SSD and motherboard that you are using, you may need to update the driver or BIOS in order for the hard drive to be seen when you initially boot the operating system.

If you experience issues when you use the hard drive adapter to boot an operating system, check with the manufacturers of the SSD and motherboard for updates.

You should also check to make sure that the SSD and motherboard are compatible. For more information, refer to the following FAQ: https://www.startech.com/faq/hard_drive_accessories_m2_u2_compatibility.


Although M.2 SSDs come in similar form factors, only an M.2 PCIe drive with an M.2 NGFF M key will operate with this device. M.2 drives that are SATA or drives that have a different key position are not compatible with this device.

This device can adapt an M.2 PCIe drive to connect to PCIe connections, which is not possible for a SATA based M.2 drive. The key type refers to the connector type on the M.2 PCIe drive, and the M key can only be M.2 PCIe. It is important to check the specifications of the drive to see if it supports PCIe M key.

Doesn't work with windows 7

By: Max Holmes - 08/17/2018
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.
Nick, Customer Support on 20/08/2018 1:52:36 PM
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! https://www.startech.com/support

The HOTFIX for Windows 7 is not to be found, error 404... Why a company would Remove a hotfix for their parts... is beyond understanding. (Product ID: PEX4M2E1)

A great adapter

By: Belala - 08/19/2018
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.

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.

Sam, Customer Support on 16/10/2018 4:00:59 PM
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. Please remember that we have Technical Advisors available 24 hours a day, 5 days a week to provide support. You can reach one by going to www.startech.com/support. We'd be happy to help with any troubleshooting needed to get our products in working order.

Fast, and easy to use

By: Nick_185 - 12/27/2018
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.

dell wont boot from this

dell i7 990 will not see it in the bois and will not boot winodow 10. no drivers from Startech

Matt, Customer Support on 6/06/2019 1:09:46 PM
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. Please contact us at www.startech.com/support where our Technical Advisors are available 24 hours a day, 5 days a week to provide support.

Works exactly as advertised.

By: NotMyRealName - 09/24/2020
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".
