How do I know whether my Mac has a SSD or HDD installed without having to literally open my Mac?

PS. Is there anyway to know it from Disk Utility?

    Does it start in a second? – Kyslik Jul 9 '17 at 18:27

  • Apple Menu -> About This Mac -> System Report
  • Select Storage in the Hardware section
  • Select "Macintosh HD" on top

Alternatively you can run system_profiler SPSerialATADataType or system_profiler SPStorageDataType in Terminal which more or less gives you the same information

  • Only the terminal command lines worked for me.I have a SSD installed in my Mac. – user244378 Jul 9 '17 at 15:15
  • Disk Utility and then Info tells you as well, as does "about this mac", and the storage tab there. Tells the bus type too (SATA/PCI/USB) – John Keates Jul 17 '17 at 1:00

Apple Menu -> About This Mac -> System Report -> Hardware -> SATA/SATA Express

For my MacBook Pro (Early 2015) this showed the Serial-ATA Device Tree, from which I was able to get the model number for my SSD. This related question, How to get serial number from Mac hard disks? might help if you think you have an HDD.
