EtcherPro has reached end of life (Etcher app is not affected)

Don't look for TeraCopy on Mac. You've already outgrown it.

TeraCopy isn't on Mac — and that's why its spiritual successors are actually better.

Unlike Windows, macOS has a fundamental advantage: . TeraCopy became essential on Windows because the old NTFS system would corrupt large transfers or halt everything on a single error.

INSANE SPEED

Fastest writing speed

We built EtcherPro with meticulous attention to the hardware, to ensure the fastest writing speed available on the market today. Each EtcherPro can write with a speed up to 52 MB/s* per port when flashing 16 drives. When writing a single drive, EtcherPro can write with speeds up to 200 MB/s*.

*As long as the drive can support the speeds.

ERGONOMIC DESIGN

Designed for usability

We wanted to offer a great experience when interacting with EtcherPro, after all, this is what the Etcher app is well known for.

The large touch screen and the slots are tilted towards the user for comfortable operation.
