softworkz 4409 Posted September 5, 2024 Posted September 5, 2024 @Napsterbater- what's your issue? Anything unclear?

I grabbed a high endurance SSD months ago to use as a dedicated Emby transcode scratch drive and was surprised to find that I've already blown through about 30% of it's expected life. At this rate I will be replacing it in less than 2 years. The majority of writes to the drive are due remuxing container incompatiblities or audio downmixing, not video transcoding. This is quite impossible when you do the math. Let's assume that your SSD would have only 2GB capacity and transcoding a 2h movie would create 2 GB of data in transcoding temp. High-endurance SSDs can do 10k to 100k writes per cell. Let's assume just 10k, which makes 20kh (20000h) of watching that movie non-stop. Means you could watch that movie 2.3 years non-stop. But now, your SSD doesn't have just 2 GB capacity. Let's assume 200 GB. This means that (due to relocations done by the firmware),, there's a factor of 100, so you could watch that movie 230 years non-stop before your SSD is fully worn out. When 10 users are watching in parallel non-stop, then it would still take 23 years. 1 1

Media center transcoding should be done to a disk. The chance of files not getting cleaned up alone is reason enough to not use memory. But trust me, the spare QLC sata disks i have lying around are not fit for anything but oversized USB flash drives, they are dram less and crap out at 35MB/s after a bit. (Pulled them out of dying machines people want me to fix). I just do it in memory for now until i get hold of an appropriate disk for it and the server has no ill effects from it.
Q-Droid 840 Posted September 5, 2024 Posted September 5, 2024 Even low end SATA SSDs that are kept trimmed should easily handle the IOPS and read/write data rates involved in transcoding and streaming media. 1 1

Exactly! Transcoding requires a lot of compute power, but storing the results is not that performance critical that it would need a RAM disk. Not even an SSD. Even more when looking out for using TVnext. It can write loads of data to transcoding-temp (for time-shift buffer and when working with full transponder data), so there's a requirement for storage space but not storage performance. 2
