The most thorough, comprehensive tutorial that I have ever seen. You have essentially "left no questions unanswered" in regard to Formatting, Partitioning and Creating Volumes in an Mac environment. Thanks much for sharing your expertise my friend.

[AdventuresInTheSky]

Best video for explaining partition vs volumes. Volumes with APFS rocks! Have an SSD and one volume for Time Machine and one volume for general storage and Time Machine can use whatever space it needs to do its thing as time goes on. Great job APPLE.

[mkcortinatony]

I was really struggling with the concept of partitions and volumes. This was just what I needed. Thanks!

[kirkydaturkey]

Simply THE BEST. Thank you Joel. You touched on all of the additional situations that I've been confused about. Other people would break this up into separate videos, and I got lost just trying to find something that addresses it all.

[blunderbus]

Joel, you are an excellent educator, this video is concise, comprehensive. Thank you for taking the time to produce this video.

[cryptochris]

Great explanation. Exactly what i needed for using the same hard drive to back up multiple laptops. Thank you!

[chrisweppler]

Great video, Joel! You made this stuff SO easy to understand for a person who's not "technically inclined."

The International System of Units (SI) denotes (exa) as a multiplication by the sixth power of 1000 or 1018.
In other words, 1 exabyte (EB) = 1018bytes = 1, 0006bytes = bytes = 1, 000 petabytes = 1 million terabytes = 1 billion gigabytes. To put this into better perspective, You could fit 11 million movies in 4K format would fit comfortably inside a 1 EB storage device.
To get to just a single EB would take 763 billion floppy disks or 1.5 billion CD-ROM discs, In the end data centers and large-scale computing environments that mainly use EB.

(Hope this satisfies anyones curiosity)

This video is an excellent video where you can find all the answers you are looking for on this subject, Thanks

[watchaddicts]

Excellent job! You're a very good (and thorough) teacher. Thank you.

[simonmorris]

Thanks so much Joel, really clearly and simply explained with great graphics. It really helped me set up and partition my new ScanDisk SSD bought to use as back-up for my MacBook Air.
I also liked the extra tip for labelling the desktop icons for my drive 👍👌👏

[weldonf]

Excellent tutorial!! Now I understand containers and volumes. Thanks for creating such a clear and understanding video.

[NewDawnBreakingMoon]

Suuuuper helpful! very straight forward and easy to understand. Thank you!

[michaeljohnson]

I cant tell you how much I love your attention to detail (makes my computing OCD happy), this has bee a great overview of partitions and volumes. I've been racking my brain on how to set up my "Travel" SSD for my Work/DJ laptop, and this has made me change my tune from 2 partitions to just running volumes on ATFS. I've been trying to decide the best way to have a "travel" backup on one section, and then my Music and DJ related files on another section to create some redundancy for worst case DJ issues.

Are their any disadvantages of assigning a volume to a Time Machine backup as opposed to leaving in the main area and just giving it a max size for backups? I'm going to start searching your other videos as well, but if you have a clip that specifically discusses this let me know where and I will jump on that!

[pixienix]

this is everything I was looking for! thanks for going into detail and touching upon the differences!!

[Harshikaj]

This is such an amazing video. So helpful!! But still I have a question, what's the exact need of creating partition or volume? I don't think.

[mmctro]

Outstanding video! You just got a new subscriber sir.

[Aviator]

Question/Statement: I'm finding myself a bit confused here. You never actually explained, (or maybe I missed it) what the benefit is to having "separate rooms in the house" really is... Only that, you prefer it that way. Essentially, by that logic, isn't a folder the same exact thing as a partition then? I mean, why not just organized "Photos" and "Videos" into separate folders within the same "house" (SSD)? It keeps everything separated, and categorizes what area of the hard drive to go to, in order to access the data you need. The only benefit to making a partition in this video that I can surmise, is so that I can run different formatting languages on the same drive. Am I wrong here? Is there a greater purpose to having partitions? If one becomes corrupt, does that protect the others from becoming corrupt? Also, if I have multiple partitions using different languages, can I easily move files from one partition to the next without issue? Thanks for any and all clarification!

But how do I partition mac for 1. DATA and 2. APPLICATIONS?? I'm just a beginner..dpnyou have a vídeo on that? I had tonreboot my mac 😢

[diegoescudero]

What If I have some files in my external SSD? those will be deleted?. Thanks for the video explanation I really appreciate it!
