Is it better to transcode to the same SSD drive that Linux is installed on (/tmp), or is it better to install a 2nd SSD drive for transcoding only? Please note the Linux box is a dedicated Plex server and not used for anything else.
its better to not transcode to SDD at all, if you want to avoid any unnecessary writes.
transcoding is not normally limited by disk performance, its generally limited either by how fast the client connection is.
if you have lots of ram (i’d recommend 32g min), on linux you can use /dev/shm which is a built in tmpfs ram drive, but it is limited to 50% of your system ram. So 32g ram will get 16g devshm space.
transcode to ram, does not increase your transcode speed, it only avoids writes to disk.
otherwise you should be fine with any old extra spinning hdd for transcode folder.
Thank you for the excellent reply. I am building a new server and can easily increase RAM instead of a 2nd SSD. Currently I am transcoding to a separate 5400rpm drive and was wondering how I can improve performance. I will certainly implement and max out the RAM.
Thank you!
one thing to be aware of, if you transcode to ram, it needs to be large enough to cover all simultaneous transcodes you may have going on.
Like remote clients, and dvr recordings.
Dvr recordings in particular can grow large, especially long 2-3+ hour movies (or sports).
I have 64g of ram (32g devshm) and had some nascar recordings end prematurely due to insufficient transcode space.
Just something to keep in mind.
This unit won’t be using DVR, only remote clients with max 1080p transcoding. I think transcoding to RAM is the way to go with my setup. The new Z390 mobo can take up to 64 GB. Will I need high performance RAM?
i would not pay extra for ‘high performance’ ram, because as far as transcoding, ram is not going to increase your transcoding speed anyway.
memory performance is ultimately a nebulous area, as in it is incredibly difficult and situational for humans to even notice any difference in different levels of ‘ram speed’.
I would go with quantity over performance.
Extra ram is always useful for disk caching (which OS will use automatically as needed).
Thank you again for the speedy and informative response!
