Late 2014 5k iMac SSD Upgrade?

[Draza74]

So I have a late 2014 5k iMac with the OEM Apple 250GB SSD in it.
It does an alright job (650ish write, 710ish read on Black Disk) but I want something faster..
So I found out about the Feather-M13-S SSD!
It says it will work with my iMac but it claims to have TWICE the speed of the OEM Apple SSDs which I highly doubt..
Does anyone here have experience with these on this particular model of iMac?
I feel like the PCIE slot is already being maxed out and buying this would be a waste..
Thoughts?

Thanks.

Feather/HatSSD/Fledging drives are homemade NVME drive + sintech adapter

They basically buy both the drive and adapter from sintech, assemble the two parts and sell them to you with a profit.

The problem is they will ship you a drive that may not be great performance for your use case.
In one comment on their page a customer said he received a Intel 660p, which is QLC and not good for sustained write speed.

You can just buy yourself the NVME drive you want (example a quality Samsung) and buy a sintech adapter

Ah, I see.
But I want to be sure, will this in anyway speed up my boot times? (depending on the drive I pick of course)
I just assumed that Apple SSDs for the time (2014) were already at the max they could be for the (I think) PCIE x1 slot.

"Light Bulb!" We now know why the iMac's Flash Storage is slower than the Mac Pro's (even though they have the same Samsung based XP941 blade). The iMac's flash storage is running at a PCIe link width of x2 while the Mac Pro's storage is running at a PCIe link width of x4.

OP:

Your speeds may not be "the fastest", but they aren't really bad.

To make a long story short, my advice is "don't mess with it".

It's still doing fine. Accept it "for what it is".

If you want "significantly faster", then you're gonna have to buy something significantly newer...
