>Any other good options?

I would be very tempted to set up an old(er) PC with as many drives in it as 
you want for the total desired capacity, and set them up as a raid array, to 
mitigate against failure. Then have the one large drive shared for access 
across the LAN.

A side effect of doing things this way is you could set up, at a later date, 
another raid array to appear as a second drive for extra capacity, or to 
mirror that array as further failure mitigation, with this being invisible 
to the users, apart from downtime while being set up.
