New “Shingled” Hard Drives Hold Terabytes for Pennies a Gig

I can't seem to see the benefits of this, considering a regular 4TB HDD seems to go for ~$140-150[1].

I could understand if speeds were similar or prices or way lower compared to a traditional HDD, but is it really worth the extra SATA connector you'd gain?

Besides, I'd personally take the risk of loosing 4TB at once instead of 8.
