Well it is not a problem with Channels as it can easily handle multiple recordings without issue.
Then there must be something wrong with the setup if there are performance issues. I am not sure why anyone would use a PI for this anyway. Seems way to underpowered for the task at hand.
I’ve got my SSD in hand. Now all I need is the time to set up. That’s this weekend’s task. And I noted the devs’ silence on the matter also.
Maddox did respond right below your initial post.
Right, more clearly, notice that none of them are saying the Pi can't handle this? Everyone seems to be chiming in with wive's tales here about hardware. The people who support the stack, and those who have used it, know better.
Let’s do this: I’ll set up using a USB hub with an SSD, both changes from my original configuration. If it works, I’ll say so. If it doesn’t work, I’ll report that.
The DVR is not CPU-bound. So it doesn't matter if you use a Pi or an Intel CPU. The limiting factor is I/O throughput. Of-course a NAS is going to perform better, it has multiple dedicated drives and uses a direct SATA interface. The Pi is limited by USB, and the issue here is crappy WD drives which are designed for archival and don't perform well when you're writing tons of new recordings to it every day.
Late to this thread, but want to report I had major problems with multiple WD Elements drives. Aman worked tirelessly with me over a period of months. Updating the way the drive was mounting helped, as did figuring out more TRIM support. Powered and unpowered, the same result: inconsistent performance and random slowness to the point of messing up recordings. Ultimately, I gave up. I've been running on a 2TB SSD for some time now, and haven't had a single problem.
I added a powered USB hub and replaced WD HDD with a Samsung T7 SSD. And I’m happy to report that all works perfectly now. For fun I recorded eight shows simultaneously and watched, paused and FFed a live program, and everything zipped right along with zero hesitation. Thanks to users and devs for your suggestions. I will NOT be abandoning Channels anytime soon.
Glad I stumbled upon this thread. Last time I tried a USB hub years ago, they weren't useful at all. Looks like that's no longer the case.
Curious @Suds, which hub did you buy?
Cool. That is the exact same one I use. Haven't had any problems. I use it with my Synology 220+ (officially Synology doesn't support USB hubs, but this one works). Actually to avoid any power issues ALL my devices are powered. Switches, hubs, drives, what-not.
