Getting comfortable
Maybe so. I ran a small micro system and external USB drive for a while after my main server died waiting to find a deal on another. Worked fine mostly but now and then when doing various things I'd get the same. Server itself never seemed taxed much. Eventually "shucked" and swapped the drive into my new server and I don't think that I've seen the same since. But the new system is quite a bit better overall too.
Does anyone else here store their video in a Storage Space? JBOD or otherwise? How's your performance?
From what I've read over the last couple of days, SS can suffer from performance issues, but generally in write performance, and especially in a parity-stripe configuration. Random Read performance is generally on par with a true RAID 0 or RAID 10.
My V: volume is formatted at NTSF with 64K cluster size. Disk loading doesn't seem to show any issues. Here's the Task Manager on my BI box while I'm watching UI3 from another machine, Live, with 16 cameras showing. As expected, there is no Read activity. Write speed varies a little bit, but tends to peak around ~16 - 18 MB/sec. I have not observed it going higher than 20 MB/sec:
When I switch to Timeline, with 4 cameras playing, I see:
When I'm scrubbing and skipping through those 4 cameras in Timeline, and it stalls, I see pretty much the same thing:
I'm not sure what queue length tells us, but it never even gets up to 1.0. Here it is when stalled:
