Similar to the last deal a month ago: https://www.ozbargain.com.au/node/277498, but without the further $20 drop (yet?).
Just your standard desktop AC-powered external HDD, with plenty of storage space. Probably a SMR drive inside, so maybe not so fast for random access, but good for bulk data storage. Don't forget to keep backups!
Lowest it's been since November, and probably won't go that low again without Black Friday etc.: http://camelcamelcamel.com/Seagate-Expansion-Desktop-Externa…, still far cheaper than any AU shops: http://www.staticice.com.au/cgi-bin/search.cgi?q=8TB+Externa…
I've been watching this since my last order was cancelled after it got damaged in transit… fingers crossed that this one makes it!
