Does anybody knows actually the real writing speed for it ?

It is around 2.55MBs, which takes forever and the drive gets really hot, to the point I am worried that it might melt down. Better stick your phone in the freezer while it is copying 100GB worth of media.

Is the outer shell plastic or metal?

its plastic, but a hard plastic. i got one cz i have macbook and a pc. this thing is tough as nails, i have it on my keys and they are thrown around the place. its a good buy !

How long is the usb C plug. I have a rather thick case on my s9+ and there is restricted access to the usb port. The plug would need to be 8mm long

Somewhere between 7 and 8 mm - silver bit, but black part is tapered so it might still fit ?. However, suggest you look for a usb-c extension lead (or male to male & a female to female connector - I use both that work fine together) that fits, so as to solve the prob for all.

dos it work on play back on a galaxy tab for play back

Yes, you can access it like a normal drive.
