Hi there, I just bought a second hand Mac mini 2014. The previous owner told me that it was HDD. But I saw medium type was SSD. So can anyone tell me what is it? Many thanks!
This belongs in the Mac Mini forum, but I can still answer the question
HDD can be (albeit incorrectly) used as an umbrella term for all fixed disk drives (so both spinning platters and SSDs). Likely what they meant was that it came with a hard drive installed. This would be important to note because not all used computers come with one, as it's often easier to remove a hard drive from a computer rather than to wipe it.
