2017 iMac : fusion drive details

Hello,

Like other people I was wondering about the Display Target Mode : will USB-C (Thunderbolt 3) will allow this feature again???

But my point in this particular topic is the fusion drive : I am thinking about a new 5K iMac, but I still see the 1Tb and 2 Tb options for Fusion Drives. Does anybody have a clue if the 1Tb is still having the very low 24Gb SSD part? and The 2Tb FD has the 128Gb part? Apple emphasis was about SSD speed improvement, but not on Fusion Drive...

Thanks for your hints or piece of info!

Hello community,

I have found some extra details in Apple description : "The 1TB Fusion Drive pairs a 1TB hard drive with 32GB of fast SSD — enough to store important macOS files and applications to ensure fast startup, near instant wake from sleep, and quick application launching, with room left over for your most frequently used files and apps. The 2TB and 3TB Fusion Drives pair a larger hard drive with 128GB of fast SSD storage"

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.

verified, on the apple site under storage specs, it does state "The 2TB and 3TB Fusion Drives pair a larger hard drive with 128GB of fast SSD storage,"

next, and more important question. What is the speed of the spinning disk portion? is it  7200RPM, or 5400RPM, and its read/write speed?

that's what exactly I'm wondering

One question.

I have an iMac top 2013. i7 / 16Gb / 3Tb fusion / GTX 780

I haven´t fusion configure... Have 128SSD separate to 3Tb.

128SSD to 3Tb fusion configuration in my iMac is SSD PCIe x2 (5.0 GT/s), 550mb/s r/w speed more or less... so new iMac 2017 is possible to has ummm PCIe x4? Whats spect?

Thanks

Hi, it can be done and I had to after a repair by Apple left them forgetting to run the process. This link will show you how to do it but; unless you're very confident, take it back to Apple and get them to do it properly as they should have in the beginning.

Hope this helps, :-)

Why, mac mini (late 2012) 2.6GHz 1tb fusion drive paired a 128gb ssd as follows:

Physical Volumes:

disk0s2:

  Device Name: APPLE SSD SM128E

  Media Name: APPLE SSD SM128E Media

  Size: 120.99 GB (120,988,852,224 bytes)

  Medium Type: SSD

  Protocol: SATA

  Internal: Yes

  Partition Map Type: GPT (GUID Partition Table)

  Status: Online

  S.M.A.R.T. Status: Verified

  PV UUID: DA55B080-40DC-421E-9FD6-2CDA3C6573B3

disk1s2:

  Device Name: APPLE HDD HTS541010A9E662

  Media Name: APPLE HDD HTS541010A9E662 Media

  Size: 999.35 GB (999,345,012,736 bytes)

  Medium Type: Rotational

  Protocol: SATA

  Internal: Yes

  Partition Map Type: GPT (GUID Partition Table)

  Status: Online

  S.M.A.R.T. Status: Verified

  PV UUID: 3FE810D7-41E2-4FC0-9681-4320B0924627

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.

Thanks jcsuperstar for the info.

Really? I was eyeing to buy this model:
