What's the point of the seagate archive now ?
Ironwolf, for the same public price, have better performance (obviously) and, more surprising, a better MTBF.
 
​I have no real insight into whether Seagate are still pursuing the product design, but I'm not really surprised that the MTBF is worse: if the shingled disk must write some tracks twice for each individual track write, it seems logical that there will be more write stress and therefore shortened lifespan, no?

I contacted seagate and just got a reply : they don't have strategic information to share about SMR technology at the moment.
I guess i saw it coming ^^
