What are your thoughts on the Ultrastar DC HC320 8TB HD? on amazon there is a good deal for them.for a 2 bay nas like asustor lockerstor 2 or synology ds718+ are they a good fit in terms of noise and heating?I’ve read that they a no more noisier than ironwolf when copying, but they are hotter than ironwolf
HGST drives are slightly noisier, but you can expect very similar heat generated. HGST drive life expectancy is much longer and they do survive harsher environments. You will therefore get 2 extra years of warranty. Also, read/write speeds will be better. These are enterprise-level drives. If you do find a good deal then they will be a superior choice.
I hope this helps.
