Is it possible to exclusively use a PCIe SSD on this mac?

I have a 2013 iMac, 27", 3.2GHz i5. Bought new, it had a 1TB HDD. I have changed it to a 1TB SSD, via SATA. I am wondering, can I purchase a PCIe thing, (blade storage I think it was mentioned as...?) And have that run as the drive for the whole system? so I could remove the SSD in there and it function, ideally faster? I trust I'd need a "PCIe 2" compatible SSD. What would I need to purchase in advance to make this work? Thanks, Rory.

It appears that the 3.2GHz did not use a blade but the 2.4GHz did. Here are the SSD options for the 2.3:

BUT the guide is showing it can be blade upgraded:

@mayer - Looks like OWC no longer offers the older mSATA blade drives ☹️

Well… it’s not that simple! So while you could swap out your current drive, Apple uses a custom interface for their blade SSD drives iMac Intel 27" EMC 2639 Blade SSD Replacement while OWC offers a pin compatible drive which is blessed by Apple, some people try to force in a M.2 SSD using an adapter.

The problem here is Apple never published their standard and only OWC reverse engineered it! They were able to strong arm Apple which is why they are the only true compatible drive.

Now jumping back to M.2 SSDs there are a good handful of different units out there I’m not even talking about manufacturers! The standard offers five different generations in three different sizes! Some won’t be any faster than what you have. And even the ones that are your systems can’t support them as those are much newer.

Here’s a great read on what Apple produced The Ultimate Guide to Apple’s Proprietary SSDs as we can see your systems Blade drive port is just a different flavor of SATA! That your current drive is using as well via the standard SATA port.

So unless you need more storage using a dual drive config. It’s not worth it!

Thanks for the prompt response. I am in dire need of doing this, as I need the speed- my current SSD runs at 6mbps, and I want to get a PCIe drive in so that it can be a lot faster- fusion would be ideal. Are you suggesting I need a converter? I thought it was just PCIe Gen2.0 x2, given it's late 2013...? Maybe I put it under the wrong model! thanks, though, for such a prompt response!

@rorymacphee - I get it you need the speed! But your system can’t offer more than SATA III for either port! 6.0Gbps is the limit here. Now before you jump, how about telling what you are doing there is a way we can squeeze a bit more performance here but it’s setting up dual data pathing!

That is you use one drive for your OS and cache files the other your work files. But you also have RAM! Which you may need to boost as that can lower the need of the drives I/O

As to what your system offers, double check using the blue link I posted to the drive guide.
