Yeah it’s an extra £16 and I wasn’t running out of space using the 1 tb so to be fair 2 is overkill already even for £16 it’s just not worth it and would likely die again before I filled it lol (have a 1TB ssd and around 350gb in other ssds from years off adding them) 
 
my froogle brain kicked in but you nearly got amazon the extra out of me !!! 

Correct. Should be fine. SMR reads about as fast an CMR, so games will load about the same. They will install a bit slower, but you install games ones.... and yea. 100mbps is 12.5 MBps.... (MB is 8x mb). So 12.5 MBps is a total non issue. SMR will not be your bottleneck here. 
 
Whichever is cheaper. Everyone will complain about one company or another. Or swear by one over another. Fact is. They all, on average, make reliable drives. I did end up buying ~12 of seagates BAD 7200.12 3TB drives. I think 8 of them ended up failing, and 4 of the refurb units I was given as RMA failed as well. Those were flawed drives. I’m sure WD has had their issues as well. So really, whichever is cheaper. Odds are if one ends up having a horrible issue, we won’t know for a while anyways. I know that sounds ominous and not reassuring, but it’s much more likely neither will have issues

Perfect exactly the info I needed thank you again. 
 
will pick up a 2tb barracuda simply because it’s the same price as a wd blue and comes a day earlier from amazon. At £60 it can’t be horrible right ?
 
Either way though thank you again for the speedy advice and reassurance.
