SuperSpeedBlazer claims to boot Windows on a Mac in 10 seconds flat

Apple has supported dual-booting Macs for years with Windows Boot Camp, but switching from macOS to Windows requires precious time and storage space. A new device called SuperSpeedBlazer promises to change that, using a high-speed USB 3.1 memory stick to boot a Mac into Windows in only 10 seconds — with a few caveats.

SuperSpeedBlazer’s premise is compelling: Developer James JY Cho pitches it as a plug-and-play way to quickly boot the same Windows desktop on a Mac or Windows PC. You can choose between a USB-C or USB-A connector based on your existing computers, and assuming they’re USB 3.1 capable, the stick can deliver up to 1GB per second transfer speeds. That’s two to four times faster than common USB flash drives, and fast enough to transfer a 4GB movie in roughly five seconds.
