sorry for the confusion and admire your observation. I think I did not make it clear about the first one (file storage). The user should get one box, where the emphasis is on the full path + file name. The second one (block) should get four boxes because the user gets the whole data (four boxes). The object storage should emphasize ID and metadata (decription of the data). Thanks a lot for pointing out the confusing part. Many thanks.

@@ShuxiangSun123 Thank you for letting me know the intentions. Makes sense now. I’m old in the game so I really want to wrap my head around when and why to use specifically object storage. I like your videos and watch many of them. Thank you for sharing. Do you have an online class / course to attend?

Good question, but what you are referring to as "blocks" is actually called sectors on a spinning drive, and block storage is different. These are the concepts of Enterprise-class storage that Sunny is making easy to understand by giving examples. Please check for how hard drives work. Here is a link to a video that explains very nicely; hope it helps.ukposts.info/have/v-deo/r6SVoperpIyVqps.html

Yes, your computer also has storage, and it's local. When you are dealing with laptops or desktops, they will mostly have one or two drives, and they are local to the system. But here, Sunny is explaining the server or enterprise-class storage, which is used in Data Centers. What you are referring to is applications or contents, and Sunny is explaining the concept. If you still have questions, please invest some time in the CompTIA Server+ topic "Server Hardware Installation and Management". Good Luck.
