Found out what happened to the Ebay Ironwolfs, Evri didn't pick up from Parcel Shop so got an email from seller saying he had sent them tonight. Tried to cancel but seller said he had posted so will have to be returned.

You don’t need IronWolf drives. They are designed for continuous use in a NAS. For your use cheaper drives would be more than adequate.

Certainly for NAS use or maybe at a pinch in a DAS that is in constant use.
If they are just going into a dock, then as you said a cheaper drive can be used.

Well I tested them then showed the results to Seagate Support. Seagate support advised me to return them after seeing the SMART data for replacement. The reason :- The raw read error rate was too high according to the Victoria app. I have since read on HDDGuru forum after asking the question about the raw read error rate seeming too high according to Seagate Support (for new drives) that this is normal behaviour for Seagate Smart and the poster linked to documents from Seagate showing the raw read error rate (ID 01) is in fact logarithmic not linear.

So on a surface check where all 4TB sectors are read its likely in fact for ID 01 to seem high. All Seagate drives behave this way. You would think Seagate Support would know this. Replacements arrive Thursday from Amazon Direct with Amazon part number.

Enter the Raw Read Error Rate and it tells you what it means.

In my case I had RRER of 30864979
Result: 0 errors in 30,864,979 operations.

Oh good grief, life is far to short, get one from a decent computer parts seller, like Scan.
Pay a bit more, but at least you don't have to bother with all this stuff, unless you like bothering with all this stuff.

Thanks for that Zaggie that is what I was told and it might have saved a return if Seagate Support (first line) knew this.

Well received the Ebay Seagate drives today and they check out. Warranty is til 28 April 2028 according to Seagate checker and both have been registered successfully with Seagate. Both have Data recovery plan in place. They came in Amazon envelopes but were inside a protect box. Will be running a conveyance test later but have arranged for the Amazon drives to go back for refund. I found a bargain at last!

Well looks like Royal Mail have lost my Amazon drives return. Tracking is sitting at 'collected' and has done since Saturday. Have contacted Amazon and they say I will not be charged, we will see if I get a refund.

I've had similar and the package has been delivered the following day.
