How fast could you move it?

Estimate how long your data takes to move at line rate — and, if you know your speed today, how much you’d gain. The catch most calculators miss: your speed isn’t your bandwidth, it’s how much of it you actually use.

With Zettar — line rate

Estimates assume your storage and hosts can sustain the link — Zettar’s co-designed appliance realizes ~90%+ of available bandwidth (over 96% in the SLAC/ESnet record). The real ceiling is your whole end-to-end path, not the link alone. Get an exact estimate for your environment →

Why these numbers

Speed is utilization, not bandwidth.

A fast link does nothing if your mover can’t fill it. Single-stream tools like rsync leave most of your bandwidth idle; cloud-native paths lose 30–50% to overhead. Zettar is co-designed across storage, host, network, and software to run at line rate — so you finally use the bandwidth you already pay for.

FAQ

Common questions

FAQ

How accurate is this estimate?

It is a planning estimate. Zettar realizes ~90%+ of available bandwidth (over 96% in the SLAC/ESnet record); any comparison uses the current speed you enter, not an assumed figure for other tools. Your actual ceiling depends on your whole path — storage, hosts, and network — so book a demo for an exact figure on your environment.

FAQ

Why is Zettar so much faster if the link is the same?

Because speed is utilization, not bandwidth. Single-stream tools like rsync, and cloud-native paths, leave most of your link idle. Zettar is co-designed across storage, host, network, and software to run at line rate.

FAQ

What is the realistic ceiling for our environment?

Whatever your end-to-end path can sustain — Zettar fills ~90%+ of it. If your storage or hosts are the bottleneck, that is the limit, and our co-design targets it. A demo gives you an exact number.
