[Alvin777]

Hello Mac and Apple friends, just curious, what is the capacity of the Apple Blade SSD n a 2TB Fusion drive in a Late 2015 5K iMac?

Thank you.
God bless, Revelation 21:4

I believe it's 128gb.

You should be able to see this in disk utility.

The 2TB and 3TB Fusion drives have 128GB SSDs.
