Robert , Daniels is referring to a Seagate proprietary raid function. Noticed the date is 2006 for the link above. It got to be a wannabe technology which Seagate hoped to charge royalties for.  LSIlogic based raids do not use data off of a failed drive to recover data as per the link ; I  could not find references to any other raid providers adopting this. [URL] This link is on a page dated 2015, guess Seagate is still hoping someone will adopt it. 
Hi Folks, I would like to utilise Seagate Enterprise Capacity disks in an R730 host that I am specifying, partly due to these disks having Seagate's RAID rebuild feature. Does anyone know if the H730P controller supports Seagate's RAID rebuild technology?  [URL] Seagate's RAID rebuild allows partial copy functionality of failed disks by enabling a failed drive to actively assist the host in retrieving the maximum amount of data possible before a RAID recovery is commenced.  Cheers, Daniel  
PERC H730P Seagate RAID rebuild technology compatible?
