There are various posts about this/these Seagate external drives... Amazon references the "Desktop" STKP14000400 as "newer" than the "402" Expansion version (counter-intuitive) - this, from the Seagate store on Amazon. On the outside, both external drives look identical. I know there are examples of both the Exos and Iron Wolf Pro drives used in "the 14TB External Desktop/Expansion Seagate"... The price is just about the same.
Is there any knowledge of what may be different between these two external drive models? I'm half tempted to buy both and use a Disk Utility to identify the internal drives.
One tends to think newer is better with tech, but in recent years a lot of companies have focused on driving cost out of their products so I'm not immediately inclined to go for "newer". I currently have the "402" (older version) ordered and will be receiving tomorrow. Performance of either internal drive is similar, but the Iron Wolf Pro durability rating is only about 60% of the Exos. Supposedly, for 10TB and above those would be the only 2 options you would get with this Seagate External drive. In reality, either will work for me as they will host my Time Machine backup data from my Mac Studio (I'll need to reformat them). I saw some Costco posts of this external drive and that has even a different product code... but every Costco drive shucked was an Exos. I don't intend to shuck mine. BTW, Costco no longer is offering this external drive for sale on their website.
