title: Confusion on disk types in gcloud when creating a new disk
body: <p>So I'm looking at the <a href="https://cloud.google.com/compute/docs/disks/" rel="noreferrer">disk types</a> available on the google cloud platform and they have <a href="https://cloud.google.com/compute/docs/disks/#pdspecs" rel="noreferrer">Persistent disks</a> and <a href="https://cloud.google.com/compute/docs/disks/#localssds" rel="noreferrer">Local SSD disks</a> (from reading their documentation). After dreading the docs I go to create a disk the disk types are labeled as 'SSD Persistent disk' and 'Standard Persistent disk'. They seems to be named different here to in the docs. I just want a confirmation that:</p>
  
  <p>SSD Persistent disk = Local SSD disk</p>
  
  <p>Standard Persistent disk = Persistent disks </p>
  
  <p>I'm new to running VMs on a cloud platform for hosting your own site and im trying to wrap my head around the different options available for all the different settings and why you would choose one over the other.. </p>
  
  <p>I'm trying to learn the different disks available and what they do but when I go to actually create a disk the types they have avaliable aren't even the same as the ones they list in the docs. I figured they could be the same but named different for whatever reason so I wanted to come here and confirm if thats the case.</p>
