Which SSD PCIe Is Right For My ASUS Z-97A / USB 3.1 MB?

I am running an Asus Z-97A / USB 3.1 motherboard (https://www.asus.com/us/Motherboards/Z97AUSB_31/specifications/) together with an older OCZ 256GB SATA 3 SSD that is only for purposes of running my OS (Windows 10) and has read and write speeds of roughly 450-500 MB/S.

Today I was about to buy a Samsung 960 EVO 250GB PCIe SSD to move my OS over onto it since they are relatively inexpensive now and have read and write speeds that are about 3 times faster than my existing SSD. I figured it would do two things for me:

1 - Speed up boot time of my OS and loading of large programs like Photoshop.

2 - Free up a SATA3 slot on my MB for the addition of another 4TB SATA 3 HDD for data storage in the future.

Then at the shop where I was going to buy the EVO 960 today the guy told me if my MB doesn't support NVMe then the SSD might not run on my MB at all. I also read a bit more about the specs of my MB and realized that the PCIe 3.0 slot is only 2 lanes and not 4 and that I wouldn't probably get the full speed out of this EVO 960 drive.

Then I read some other older threads on forums where people were also saying I may only get read and write speeds of about 500MB out of this Samsung EVO 960 drive, same as what I got now, so, so far, I haven't bought anything.

I have 2 questions to help me decide what would be best to do:

1 - Are there any 256GB SSD drives that are PCIe based, which are 2 lane that I can hook up to my MB, which are designed for the specs of my MB, and would give me read and write speeds that are faster than what I am getting now, which is only about 500 MB/S?

2 - Is there a cheaper and lower spec PCIe SSD than the Samsung EVO 960 that would at least give me comparable read and write speeds to what I have now of 500 MB with my OCZ SSD so that I can still free up a SATA slot on my MB, but for less money than buying a Samsung EVO 960, which around $125 at the moment?

Thanks for any insight and input you might kindly be able to offer.

 
First, as of BIOS version 0501, your board supports NVMe (https://www.asus.com/us/Motherboards/Z97AUSB_31/HelpDesk_Download/ check under 0501, point 3)
So I see no reason why you could not use that EVO. Note that using M.2 will disable both PCIe x1 ports (and most likely you will have to turn on M.2 first in BIOS).

Thank you for that info. I am already running a newer version of the BIOS and do plan to update to the latest version soon. So I am good to go on the NVMe issue it seems. Thanks also for the tip on the M.2 setting in the bios. I will check it out. Thanks again.

I've been bought the Samsung MZ-V6E250 960 EVO 250 GB Internal and I also have a Z97-A but the m.2 is older 2.0 not 3.0 x 4 lanes. I decided to buy the Asus HYPER M.2 x 4 MINI M.2 Hyper Interface Adapter and slot that into the PCIE 3.0 slot but from what I've read and will test, you cannot use this as a boot disk and only storage.

Have you had any success with it?
