I've enjoyed a WD Black drive.  Internal 4 GB is easy to find.  I've owned one of those for almost 10 years no issues still runs just like new.

If you went with a NAS drive (WD Red) I'm not sure what the performance or other issues might be but, I would think you would want direct ethernet 1 gb connection for it or it would be as slow as downloading/uploading speeds over wi-fi.

The NAS drive ties into the modem directly and allows for all computers in the network to use it.  I've never set one up before but I have considered it due to that feature.  However, if all you want is local storage and large capacity skip the NAS and go to an internal or external large capacity HD.

External HD are nice, again you would want the fastest connection possible, also some of those come with their own power supply.

I found a black cheaper but still more than the red 

I had a WD MyBook network hard drive enclosure and I put 2 WD Reds in it.  It was great. 

I still use the 2 reds in my computer.  They have held up nicely.

I have lost a good bit more Seagates than WDs.  I say avoid seagate.

Yes America. The one's I pointed out said free shipping, I don't know how that works in Canada. I'm guessing there's an import tax.

I got the WD Red 4tb. I like it a lot so far, out of the 4 hard drives in my computer it is the most quiet with the exception of my SSD, performace is decent too.

I never know what to tell anybody about hard drives, and I never know what to believe from the purchaser reviews.  My old WDs have been good to me though.

I don't know what are the most reliable but it seems like if you want something more quiet the WD drives are better than Seagate.
