2017 iMac : fusion drive details

Hmm. I have a new iMac 2017 4K with 1TB Fusion Drive, and the System Information details show the SSD as:

APPLE SSD SM0032L:

Capacity: 28 GB (28,000,002,048 bytes)

TRIM Support: Yes

Model: APPLE SSD SM0032L

Revision: DXZ86A0Q

It is not 32 GB by any stretch of the imagination!

I'm not sure if it is necessarily your fault, since the common understanding is that it has a 32 GB SSD for the 1 TB Fusion Drive. I think physically it is probably 32 GB, but actual usable space is 28 GB (4 GB is for spare blocks).

This boils down to marketing-speak, I believe. It's unfortunate that Apple is starting to come down to the level of providing misleading information to users.

Note: I don't know if the previous 1 TB Fusion Drive had 24 GB of actual usable SSD space?

New, 2017, 21 inch 4K iMacs come with a Fusion Drive with 256, 512 GBs OR 1 TB SSD tied to a 1TB 5400 RPM hard drive.

Specs listed here, folks!

You're Welcome.

I just got done with a chat. She said it was a 32GB SSD in the 1T Fusion Drive. Didn't ask about the 2TB.

that's what exactly I'm wondering

that's correct. the earliest fusion drive 1tb had 128 gb ssd but after a few years brought it back to the new configuration of 32gb or maybe even 24 gb as of now.

I think that as ideas go this is a good one.

Only the 1TB fusion drive is offered for the 2017 4k iMac.

Correct. My bad saying 32 when the actual number is 28.

Slow drive however you parse the number.

Did someone know hod fast is standart hdd in fusion drive? 7200/min or 5400? And read/write speeds? Thanks!

After chatting with a specialist today, she said that the HDD in the fusion drive is 5400RPM. 😕

Hard drives, regardless of rotational speed are slow.

My bad.

I read the spec wrong.

I thought the spec said 1TB Fusion Drive with 256 GBs or 512 GBs SSD.

I didn't see the "OR" after the 1TB Fusion Drive description.

Again, My Bad.

Sorry.
