Check diskprices.com. Back before the components crisis, about $14/TB was a good deal, nowadays it looks to be more like $25/TB. (Filter out SAS drives unless you have SAS connectors.) Yours is $28/TB which is not terrible, but it does look like there's some drives which you can even buy new at that price, so it's not a steal or anything. In general the things to look at are >SMART readouts, make sure there's no issues but also check e.g. total power-on hours to get an idea of its wear >cross-reference with the Seagate official table of which drives are SMR, to make sure it's not >do you even need to hoard 8tb of data for anything or is it a "just in case lol" impulse buy SMR, for reference, is cheaper but makes overwriting data VERY slow. It's acceptable for backups or long-term storage where your data will pretty much be write-once, but it's always worth less than a proper CMR one. If you do want the drive for backups or whatever, you can try asking your friend for a cheaper price. That or grab one of the deals from diskprices
