Enable compression?

[thepregnantgod]

What do you folks feel about enabling "compression" via Disk Management?

 

Most of my media are ripped movies.  My only recollection is that there would be a performance hit but considering I have a 3930K at 4.5ghz with 48gb RAM, I'm not sure that is a valid point any longer?!?!

 

I have everything Duplicated so my 70TB is actually about 35TB and shrinking...

I always wondered this too.  How much would you really benefit from it though?  And also would it really be worth it to compress media thats already compressed?  (Assuming you re-encoded video into some compressed format)

I did it once out of curiosity it did save some space but not a lot but I also ended up with a few corrupt files so I didn't bother after that

For those interested...lessons learned:

 

1. Slows my system to a crawl (and I have a beast system - specs below)

2. Completely useless when compressing large "uncompressed" media files (i.e. straight Bluray rips at 30gb are still 30gb)

3. I'm unsure if this is because it's having to do more CPU work (since I didn't see that climb) or just that my pool is comprised of 24 3-4TB Green disks which are slow to start...

 

Specs:

 

3930K @ 4.5ghz

48gb DDR3 1600 Ram

6xOCZ Vertex 4 (Raid 0) for Win8.1 x64 OS

24 3-4 TB Green Drives (WD and Seagate) = 72TB total

- connected via onboard LSI SASx8 and external LSI SASx16 adapters (non RAID just duplicated via Drivepool)

I suspect that the slow was due to both.

 

Also, lee hits the nail on the head. You're not going to get a lot of space here. And you increase the possibly of data loss by compressing the files.

 

And you may be better off re-encoding the files into a smaller format (like mp4/mkv h.264) rather than compressing. Or ripping them to that format to start with.
