But the entry level mini has a fusion drive option with a 128gb SSD: https://everymac.com/systems/apple/mac_mini/specs/mac-mini-core-i5-1.4-late-2014-specs.html
"By default, this model is configured with 500 GB hard drive, but it also can be configured at the time of purchase with a 1 TB "Fusion Drive" (which combines a 1 TB hard drive and a 128 GB SSD) for an additional US$250."
That is only because it was released in 2014 so Apple hasn't gotten around to downgrading it yet.
