Fusion Drive Missing? or Do I really only have a SATA?

[tommydlife]

Hi! So I picked up a Late 2015 27inch iMac locally for a pretty good deal I think. Looking for good memory deals to boost it up. However - I'm trying to figure out if I have a fusion drive or not. Currently, it's loaded w/ Mojave and APFS format and it only says 2 TB SATA drive.

1. I tried to run diskutil resetfusion and it say I did not have a SSD drive.
2. When I run diskutil list my output is as such:
3. When I run diskutil cs list - it outputs No CoreStorage logical volume groups found

It's a mid tier 3.3. i5 so not the base model and I thought based on the specs, a 2 TB Fusion Drive was standard.

Do I indeed only have a SATA or am I missing something. Any help would be appreciated!

Open disk utility.
In the menu bar, go to "view" and see if "show all devices" is selected.

If it IS NOT, select it.
Then review the disk utility window and see if anything has changed.

Shows only SATA Physical drive. No notation of a Flash Storage (SSD) .

Maybe I am only stuck w/ a SATA drive, or the SSD failed or dislodged somehow during transit. I've ran the Apple Diagnostic Test and passed w/ no issues.

What do you see in System Report?

I'm fairly sure this model has the SSD slot and it should have came from Apple with one. I'm thinking it somehow is loose and not connecting or it indeed did not come w/ a SSD or some kind of weird failure.

Either it is a platter drive only or the blade drive, 128GB PCI-e on your model, has died or been removed. Apple Support does show a 1TB HDD was available.

Yeah - in either case - it's still very usable as is. Just needs more Ram vs the standard 8GB. If I do every open it up, will just swap a full SSD or replace the PCI-e in since it's a PITA to open the slim-line ones. I know a 1 TB 7200 was available but this was the 3.3 Core i5 and was noted to come w/ the 2 TB (which I have) and it was supposed to be a fusion drive.
