About this product:
A standard 3.5-inch form factor CMR technology works with all capacity enterprise applications & environments
The first HDD in the industry to harness Energy-Assisted Magnetic Recording (EAMR) technology improves writability and therefore increases areal density.
HelioSeal technology is the foundation for Western Digital’s high capacity HDDs and this is the 6th generation of HelioSeal product
With its massive capacity and 2.5M MTBF (projected) reliability rating, the Ultrastar DC HC550 is ideal for object storage implementations. Object storage systems with erasure coding provide better data durability compared to RAID systems, given their tolerance for simultaneous error conditions.
2.5M hours (projected) MTBF rating & 5-year limited warranty
