windows equivalent for dd

Try Win32DiskImager , it can write images to disks.

Just use dd for WIndows ... it works perfectly even though it is quite an old project.

Rufus works as expected. Choose 'DD Image' for 'Create bootable disk using'.

The source is published on GitHub: https://github.com/pbatard/rufus.

balenaEtcher is another Windows compatible tool for writing writing images to USB drives. It's also fast, and is easier to use than Rufus.

My experience: Win32DiskImager did not detect u-SD through a USB-3 reader; dd for Windows, MinGW compiled dd, Unix Utils dd, and Linux dd VIA VirtualBox VM USB3 pass-through were all unacceptably slow; I have yet to find a Windows command line equivalent that can beat the 50MB/s write speeds I'm seeing with Rufus.

First I also tried Win32DiskImager, which I thought is doing only partition copy based on its display (no, it can backup an entire SD card), so I continued searching.

My current favourite is HDDRawCopy. It copies to/from file an entire disk image, but not partitions separately. It creates dd compatible or compressed images on the fly - not as efficient as 7zip (does not reach ZIP performance even) but you don't need to touch the image again.
