I think you should've mentioned additionally that ephemeral storage is the storage that comes on the physical host that the VM is spun up on. Since there are many VMs on a single host, no one gets to claim the disk space, and that's why its gone once you destroy the VM! Great video btw!

for adding some extra information to this video :
difference between block storage and NAS ( file-based storage ) :
1- in file-based storage, you have a directory that is accessible from the network and formatted in a specific file system format like ( NTFS, ext4, ... ) that you can
assign permissions to files or folders based on usernames and groups that is locally authenticated or by a directory service like Microsoft Active Directory and define quota or read and write permission. but in Block-based storage, you have raw and unformatted disk space that is accessible over the network and you can format it to any file system that your OS support.
2- if your OS is Unix base you can access (NAS) via NFS protocol and if your os is Windows via SMB protocol. both of them are over the IP network. but Block-storage is accessible over IP network or FC or FCOE network.

Really appreciate your explanation. I've been watching dozens of tutorials and read many articles, and still don't get the differences between these storage types.
You really use the easiest way to explain.
Thank you so much!

Holly Virgin Mary! A Caucasian US-American in the IT environment who actually is well-spoken! I know I may sound somewhat sarcastic but I swear to God that I had not listened to someone from the United States capable to pronounce correctly words/vocables like "Going to, Want to, kind of, Internet; have[got] to" whao! You did it for entire 90 seconds without eating your T's/D's before N's & R's. I have got to give you credit for being moderately well speaker afterwards despite the continuous "/un-narestdan/"(understand)

-Oh by the way! thanks for sharing your expertise IN A CORRECTLY ADDRESSED WAY! VERY, VERY USEFUL AND TRUSTWORTHY INFORMATION.

Very, very good explanation. A few wishy-washy explanations on other videos and google searches, but Zach this explains these concepts well. Video length originally seemed long until I realised that I may never get a decent explanation elsewhere, so for me, it was a time saver.

[horizonbrave]

Damn dude, thanks a lot. I actually hope you do more deeper dives into this stuff. I know you're a dev and as you say you "don't care" about the lower deeper knowledge but you explain it so well, and I really appreciate how you give us a very practical and real look at how this stuff looks like in real life, not just a quick explanation!

[theoneandonlyzulu]

Really clear explanation, just what I needed, cheers.

[AlexandruTanase]

I'm commenting just for the algorithm. Your tone and approach is what some big course providers out there should strive to achieve

[shankarck]

Honestly, this is the best explanation I have seen so far!! So much clarity after half hour is just amazing. Especially, the table at the end.. That helped a lot. Thanks!!!!

Best part I liked was about comparison across various leading cloud storages. Since each of them use their own marketing terminology and actual implementations are abstracted.

[twesigyeronaldk]

Thank you Zack. Very good explanation. Have used Digital Ocean for a while but didn't know what you have been explaining not until today. Thank you for the info.

[FredMasoni]

This guy is a giant! Simple, clear and to the point.

[harishbabu]

Thank you for the clear explanation. The differences between these storage types has been killing me for a well. Keep up the good work.

[abhinavtyagi]

this is the best video on storage that i could find on the internet.

[xeygarz]

Golden video - you explained everything so clearly for someone who has little or no background in the topic, WHILE managing to go in-depth about the inner workings and practical uses. THANK you!!

[Nandhakumarbkk]

Clear and lucid explanation without all the useful. Thank you

[vaastavv]

Great explanation brother.
All the other google searches just provided basic idea but not the exact architecture of the topics....keep up the good work!

[anshikagupta]

Thanks, really appreciate the last slide about names each cloud vendor is giving them, kinda lost you in the middle when there was a sudden jump from NAS to SAN while discussing block/file storage differences . But kudos ! great work

[samahome]

Wonderful explanation of different storage types with excellent diagrams and pictures.
Thank you.
