Hi.
I got an Imac 27” I5 3.5 Ghz late 2014 and want to upgrade it a bit.
I´d like to pull the spinning disk and put in a Samsung blade 970EVO (MZ-V7E1T0BW) but is it Compatible with my Imac ?
I also want to get more speed. I’m thinking to upgrade the I5 CPU to a I7 CPU (4790K) 4.0 Ghz is it possible and worth the money ?
Thanks in advance

@jonaharagon - Is correct Apple uses a custom PCIe/NVMe blade SSD as he describes in his answer.
Ideally, I would just add the blade SSD and leave the HDD alone (dual drive). Here’s a good reference on whats needed: The Ultimate Guide to Apple’s Proprietary SSDs But, it’s a lot of work!
As an option you can indeed swap out your HDD for a SSD which I believe is what you wanted to do. Here we would use a SATA based drive not a M.2 blade drive. This is the correct Samsung drive: Samsung 860 EVO 2.5” SATA drive It’s a lot less work! Loosing the HDD will force you to use external drives for your deep storage so keep that in mind.
I would forgo the CPU upgrade, it won’t offer that much of an improvement!
Adding RAM and swapping out the HDD to SSD will offer more improvement. If you really want more performance, I would go for the PCIe/NVMe blade SSD drive.
For either I would install a 512 GB or larger drive.

Thanks for the answers. I guess I´d keep the spinning disk (1Tb fusion) for storage but what I ment was to increase the performance, faster boot time etc. So I would like to know what PCIe/ NVMe Blade SSD is Compatible whit my Imac (manufactor and model) other than the rather expensive Samsung MZ-KPU1T0T/0A and OWC. I know it`s a lot of work but I mean when the hatch is open I´d go for the best performance for the money.
OK, you've added a useful piece of info! You have a Fusion drive config so presently both the SATA (HDD) & PCI (SSD) port are used with a Fusion setup. I'm not a lover of Fusion Drives if you want speed you want dedicated drives!
So you'll first need to break the Fusion Drive set so you can pull the smallish SSD blade drive and put in a larger drive in. I just did one of these upgrades the other day. The systems owner is into music production so we pulled the Fusion blade drive out and put in a 512 GB SSD in its place. We installed a fresh copy of OS onto the SSD and configured the drive as the boot drive. We put all of the apps onto the SSD drive leaving the rest of the drive vacant for virtual RAM, caching & pages as well as scratch space for the app. The system boots up in about 30 secs and launching apps is around 10 to 15 secs.
As for what drive we used Custom Samsung 512 GB SSD drive for Apple in a iMac 27" Late 2014. There really isn't anything else I would recommend. Both OWC & Transcend don't support their SSD's in iMac's not so much as they don't work, its more of the amount of work to get to it takes a lot of work. I prefer to stick with the custom Samsung drives Apple uses. You might find there 256 GB will be enough for your needs. Just keep in mind you want to leave 1/4 to 1/3 of the drive free after installing the OS & your Apps.

It is possible to upgrade the CPU to a 4790K, review this iFixit guide for some more information: Reemplazo de la CPU del iMac Intel 27" Pantalla Retina 5K
Just don’t expect any support from Apple in the future if you change the CPU out! I assume your warranty has ended anyways, but just something to keep in mind.
It is not possible to use a Samsung 970 Evo SSD however. Apple uses a proprietary connector on their SSDs, not m.2, so the drives are not compatible. You’ll want a “Generation 3” Apple SSD, according to this handy guide to Apple’s proprietary SSDs: https://beetstech.com/blog/apple-proprie...
If you get a compatible SSD, then you will be able to upgrade it with the following guide: Reemplazo del circuito SSD del iMac Intel 27" Retina 5K Display
