Im looking on serverpartdeals, and i see two of what looks to be the same exact thing, Seagate Exos X24 ST24000NM000H 589$ Seagate Exos X24 ST24000NM001C 559$

The stats are all the same. What is the difference? why buy one over the other?

I see the same with the 26tb model ST26000NM001C ST26000NM000C, different price.

the 28tb has the same two different, but same price.
