What's a Terra server's maximum ingest speed?

I am in the lucky situation of being offered some seriously high-speed internet connectivity (10GB/s!) and wondered what limits there are at K'scape's end on sending data and at my end ingesting this? I have seen some people saying 800mbps from K'scape so assume that the Terra servers at both ends can deal with this but what is the limit?

Not sure on the theoretical. 800+ is the most I think we've seen reported.

The download speeds from the Store are set by the end-user with the top speed listed as "Unlimited." I don't know what limits exist in the Terra's design, but I believe it can handle the currently available speeds from the main providers, but in most areas these speeds are still limited by other infrastructure limitations.

If you want some conjecture on physical limits, the Terra is basically a multi-hard drive RAID array using striping, I believe. The write speed of a conventional spinning hard drive usually sits somewhere above 100MB/s. Writing to raid array writes multiple bits simultaneously for each drive. Depending the drive models in the Terra then, the actual write speed is something like 100MB+ * X for the number of drives.

In any case, it's much higher than a Gigabit ethernet link can serve the bits even running at full capacity.

Given that the Terra has a Gigabit ethernet controller, that pretty much defines the hard limit.

I see 900Mbits+ to my Terra, and that's basically maxed out.

Oh duh, yeah, I forgot out that part of the connection. It would need a 10GB Ethernet to unlock more speed. Good call.

What region/state are you in to get 900+? I tend to top out around 600 in Michigan.

With a Gigabit fiber connection here in Silicon Valley, download speeds to my Terra vary widely... anywhere from ~300 Mbps to ~850 Mbps. I'm not complaining at all considering I was only able to get 25 Mbps at my last house, but wanted to highlight that different variables (e.g., data warehouse limitations, bandwidth congestion, internet goblins :p ) can cause significant fluctuation even with a high-speed connection.

fizzsnob nailed the absolute limiting factor, which is the speed of the port.

For what it's worth, just to address a comment from TrackZ, the drives in the Terra are not striped. Movies are stored entirely on a single drive within the system. Since Terra does not have a parity disk like the older Premiere servers, this ensures that if a drive fails, you don't lose all of your movies. Only the movies on that drive become unavailable until you replace the drive and re-download them.
