Suggestion for cache drive


MEB

Recommended Posts

For those of us with huge libraries that require the use of spinning drives which can be slow to spin up and start to transcode or stream. Could there be a optional feature to use a SSD to cache only the suggested and recommended media that way if we are in the middle of watching a series or marathon the next episodes or sequils are ready and waiting on a SSD. This might be hard on that drive but SSDs are getting cheaper. The feature could be customized to allow how much we can devote and such.

 

I especially want if for when I hit play on a season of spongebob for the kids and need some me time, they get impatient waiting for the next episode to start.

OOps i responded, but i didn't realize you were asking to cache "SPECIFIC" Items, so I deleted and put this text in its place...    You can use an ssd or separate drive for transcoding and cache.  If its only a handful of things you want to come up fast, just use a cheap SSD and store your things on it?   My server is pretty responsive, I have a large (i think) library and with an ssd for all of my meta data, images, and transcoding it works well...  I recently moved all of my movies to a USB 2.0 drobo mini.  Yea USB 2.0!  And it supports multiple users (haven't hit a limit yet) watching movies, the server pulls the video from 2.0 as fast as it can and transcodes to an SSD where it goes out to the users...  This process stays ahead and doesn't seem to have any issues for me.

Yeah you can setup transcoding and metadata to live on whatever drive you want.  My personal setup I have a 24 drive file server that feeds a dedicated Emby server.  The Emby server uses a 6 Drive 15k SAS RAID 5 for transcoding and metadata (blows SSD r/w out of the water) and response times are near instant.

My idea is not exactly for transcoding, I'm looking at it from a more power saving side of things. If I'm watching one of the suggested/recommended episodes or movies then it would be nice if they get cached to a ssd so that all my spinning drives don't have to spin up to search for that episode. I like my 9 spinning drives to be sleeping as much as possible and if the stuff Emby thinks I'm going to watch is ready and waiting on a ssd that would save a ton of wear and tear on those archive drives. Seems like it shouldn't be too hard to set up just when a suggested item is flagged have Emby play it from the cache and not its original location.

You're better off allowing your spinning disks to always run, while it will cost a couple more cent's a month in electricity, it will greatly help the overall lifespan of the drives.  Constant Parking/Unparking and spin up/spin down put's alot of unneeded wear and tear on a car.  Think of it like a car, a car last's a lot longer when you put alot of highway miles on it vs. constant stop and go traffic.  Same for a hard drive.  Modern hard drives use 5-15 watts of power, that's not a whole lot in the grand scheme of things.

That may be true but as I don't watch TV 24/7 having the drive power down for heat and power usage a few times a day is no big deal, and even less of a deal if a SSD could be set to hold onto the suggested episodes as those are what I watch 90% of the time. All my drives are WD Reds so they can handle spinning down even though they are designed to run 24/7. I just figured the devs could implement this feature since they seem to like to add features only a few people will use. Like the photo upload feature.

Could you not use the folder sync function to achieve this?

Would then playing back on a roku play the cached version? If it would then yes this seems like a viable option.

You would need to sync it in such a way that guaranteed the Roku doesn't have to transcode it but, then, yes.
