Anyone use a Smsung portable SSD to boot an OS from?

Specifically, I was looking at the Samsung T3 portable SSD product to try and boot a version of OS X (ahem, macOS) on a late 2015 27" 5K iMac. I just do not know if there is any intermediate software that would prevent the portable SSD from being seen as a bootable hard drive.

Should be fine.
The 27" 5K iMac only includes USB 3.0 ports, so the USB 3.1 port on the portable SSD will be slowed down to USB 3.0 speeds.
Installing and running Windows 10 should be fine as well. However, trying to upgrade an existing installation of Windows 10 (to a newer build number) may experience a balk, where the Windows upgrade process may fail. It's something I've seen in older builds of Windows 10, anyway.

I guess I should be fine since I am not touching W10.

Previously, I used a simple SATA2-to-USB3 adapter cable to connect a Samsung 2.5" EVO 840/850 SSD and attach it and clone (using Carbon Copy Cloner) to replicate the native environment of the iMac, and then successfully boot from it, but I considered more formal treatments of interface electronics found in external enclosures or evenmaybe those in the product I OP'd about might present an issue to this kind of activity.

I think I may have had prior bad experience with a Western Digital 3/4TB MyBook not being usable to install and boot externally because of some logical block translation that was being done on the MyBook in a proprietary manner. I guess this is just what I am trying to avoid. It is one thing to try and fail, but another to screw the storage product permamnently in experimenting.
