NTFS Compression, When should it be used?

I test NTFS compression in a variety of use cases to test the performance and space savings, and see when NTFS compression makes sense to be used, and when the space savings isn't worth the performance hit.

This video is gold. Exactly what i needed to know, well presented and very understandable.

I couldn't find clear information regarding performance, now it is clear that I should leave it off! Thank you for your testing, great video 👍🏼

Running a Space Engineers server. Due to constant logs and instance saves every 30min, the server is writing over 60GB-80GB a day, if unchecked the drive being a 1TB NVME, so working on 60x to 100x, the drive would wear itself down within 3+- years. Using the NFTS compression the storage used is less than 1/3 + having a high end CPU, the slight overhead in the CPU is worth it. The SE server once loaded, doesn't require the drive, unless saving the instance and updating log files.
*Note I only set the compression on folders containing logs, bps and save directory within the SE system, don't bother on the OS, rather just cleanup the OS install.

Off topic but i just wanted to say your facial features look like they are chiseled from marble. I'm slightly jealous of that magnificent jawline.

Excellent and informative. This was exactly what I wanted to know. Thank you

[Elidesentiago]

This video is soo well made, impressed by the detail and testing methodology 👏👏👏

[vladislavkaras]

That was really informative!
Would be also cool to know, when using any programs & games, how it affects CPU usage when program is compressed and not.
Thanks for such detailed video!

Thanks for this! I needed this so bad!
You answered so many of my questions within 11 min

Yeah I agree that it's a shame Microsoft has restricted their deduplication to server os versions only. However, I have noticed that Apple has at least in part made their APFS file system at least able to support the feature of file level deduplication instead of block level.

Great video, I'm surprised there isn't more tests like that on YouTube

[marcmontero]

Thanks a lot for the video, love the research and how you structured the video, im formating a pc to use it mainly for gaming and was wondering how big of a toll it would take on my pc, my question was answered!

[bananaboy]

Great video. Love that it's straight forward and the tests are good. I was a little surprised on the performance hit for games. I knew it would be worse, that not to that extent. I'll be sure only to only use it on games limited by I/O and not cpu, which is limited these days. Not to mention SSDs now in 2023 are cheap as dirt. You can get 1tb with dram cache for like $30 lol. I use an old 512 gb sata drive as a cache for my hard drive and it's great.

[elballoonrat]

So much good info and clearly presented. Thank you!

I found game loading performance was 10-50% faster when loading from a compressed ssd. Compression is pointless on harddrives, the fragmentation more than makes up for any speed gain due to smaller sizes. It should only be used on SSDs.

One other test I did was a compilation test of a large C++ game, a full compile went from ~22 minutes without compression to ~19 minutes with compression on an SSD.

how sad, so they just never went about optimizing it. i hope (for the real world) they can prioritize this over half-rewriting dialogs (i know it's a much harder task that not the same people can do. but they have a point where they decide where resources go.

so great that you went on to mention dedup, and your experiences.

Quite helped to gain some space on my laptop. I used it on old phone backups that are rarely accessed and some games that I rarely played, but doesn't want to delete. CS:GO went from 30GB to 20GB. Though of course noticed some hiccups while playing it. I might buy an external HDD though and a newer laptop and I might put a bigger drive in the future.

I inadvertently ran compress.exe. A CMD window appeared and started (what I assume) compressing my OS files. I panic-pressed ESC to cancel it because I wanted to review the compact.exe run command before actually running it. Is there a way I can uncompress or revert this process or should I not be concerned about performance or anything else?

[erichares]

Thank you for your Video I was thinking over to use it but did´nt it.

[souravpal]

So I did the same thing without knowing the consequences. I went to the
local c drive > User folder > left click the file > attributes > Click advanced > clicked "compress content to save disk space" > clicked ok > apply> ok
But here is the problem I did this without knowing what will happen, now half of my folders, content and app on my computer are gone. The user file disappeared. Now I don't know what to do and how to get back all the files because those were important files .
Please can you help me out in this situation, what to do and how to get back all those files in the previous state.
Other information are
> the user file was 48gbs last time
> I am using an Asus tuf laptop with windows 11 ( i7 4000 series, 16 GB Ram, 3050 graphics)

Isnt there is Table of Badly compressed sequences of 64bit and 32 bit ? Isnt it inside of SSD 😮🎉
