how long does it take reflect to restore a 50+ gig image in windows 10, assuming all the image is restored and wipe out any previous traces
@garry35, as @Peter2150 has said, the speed (device <HDD or SSD> and connection type <SATAn/USBn>) of the device holding the image, the speed of the processor (it does the decompression of your saved image) and the speed of your target device (device <HDD or SSD> and connection type <SATAn/USBn>) all will have a large affect on your question of restoration speed.
My images of Linux and 7 and 10 are about 45 GB I guess (including data)... I'm on a 8 year old core 2 duo laptop and it takes about 20 minutes here restoring from an external usb drive...
That actually sounds pretty good for a total restoration... I'm guessing that USB drive is USB2 from that laptop's age,
