Is the read rate high enough for 4k UHD movies?

[jamieuk147]

I'm wanting to create a pool for all my movies which are mostly 4K UHD HDR etc. I don't see a problem when playing directly via HDMI output from my HTPC.

Is there enough read rate and hopefully slowdown for streaming large files via Plex?

Thanks so much

I'd say yes, depending on how your pool's hooked up. For example mine is all internal SATA drives, I can read off them at over 90 MB/sec, sometimes as high as 180 MB/sec depending on which drive and where on the drive the actual file is, but streaming anything over my wifi tends to sustain about 45 MB/sec at most even if I'm not sharing it with anyone else at the time.

I have an Amazon 1080p Fire TV Stick streaming data via wifi and it will buffer with files ~15GB+ at 1080p. In my case, the issue is not the read speed of DrivePool drives, it is with the wifi and Fire TV stick limitations. With my external USB HDDs in my DrivePool, I get about 90-100 MB/sec read speed directly from my external USB 3.0 pool drive to my internal HDD. I would think that is what I could expect to get streaming directly from my computer to a TV.

How fast of a sustained transfer speed do you need for 4K files?
