My First submission here.
Bought this at JB Hi-Fi Fyshwick, ACT with the help of someone else here who bought a bundle of 5 for the same price (search for the receipt he/she uploaded here). The store price matched for me. Going to grab another one today to add more space into my home nas.
Internal HDD is ST3000DM001. Google suggests it's 7200rpm.
I think it is a bargain for me. Use it as external or internal, up to you!
Not bad price.!
