Hey Tero, thanks for your sensible response. That’s kind of what I’m looking at. Thanks for making time to think about it.

Thanks for a very entertaining response Jeremy. I’ve read it carefully:
“I don’t think anyone said as fast as possible.”
You yourself said “faster is better”
Jim said “buy a lot more computer than you think you’ll need”
“You asked about NVMe.”
No. I asked about general drive speed, and used the insane speeds of NVme as an example
“Get you… Read more

Hey David. Thanks for your learned reply.

My assumption is that at some point, hard drive speed will cause a bottleneck in the pipeline, and that this point is calculable. Approaching this as a scientific experiment, we’d have to theoretically remove all other bottlenecks, and look at just the speed of the drives, therefore assuming that gpu / cpu…

Hey Jeremy.

Thanks for your response. The assumptions I’m making are broadly in line with what you’re suggesting. I’m just hoping to find someone in a white coat who can share practical numbers so I can estimate at what point the hard drives would cause a bottleneck.

Cheers.

Hello Jim.

Thanks for your reply.

I’m asking a question about hard drives. To make sure the replies are about hard drives, I suggested we assume the CPU / GPU are good enough to handle what’s thrown at them. I don’t think anyone needs reminded that different codecs cause different stresses on cpu / gpu.

I’m not sure how your business is doing, but if…

Thanks Jeremy.

I get that faster is better, I’d just like to be able to make more precise calculations, as this is going to be a sizeable investment and I want to put the money in the right place.

Yes, the NVMe drives are stellar, but do 4 streams of footage that run at a total of 600MBps need storage that runs at 6000MBps? Would it run on a sata…

Hello Joseph.

I did not ask how to measure a disk’s speed, but thanks anyway.

Also, thanks for pointing out that different media will have different system demands (who knew?) even though I specifically removed CPU/GPU from the equation.

I don’t mind that you don’t know the answer, but it seems to be a bit of a waste of your time writing an…

Hello all.

I’m in the process of speccing a new edit machine and am wondering if there is an equation I can use to calculate how fast I need my disks to run to able to manage different flavours of footage.

For instance, I frequently use Raw 4k footage from a Sony F55, which Sony tells us is 1000Mbps / 125 MBps.

To edit one steam of this footage in r…
