0B48717 WD Ultrastar DC HC555 16TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Data Center SATA HDD for Nearline and Capacity Tiers with the 0B48717

The 0B48717 is a 16TB internal 3.5in WD Ultrastar DC HC555 HDD engineered for capacity-centric server and storage platforms where predictable latency, sustained throughput, and 24x7 duty cycles matter more than peak IOPS. Built for SATA-based storage arrays, JBODs, and scale-out nodes, it aligns with modern data lakes and archive tiers that demand consistent behavior under mixed sequential workloads.

Architecturally, the 0B48717 combines a 7200RPM spindle with a 512MB cache to stabilize queue handling and improve streaming efficiency in multi-drive enclosures. The drive supports 4Kn with 512e emulation to simplify integration across operating systems and controllers while enabling advanced-format alignment in modern filesystems. Helium-filled mechanics reduce turbulence and power draw, supporting higher platter density and thermal stability in dense racks. TDMR and EAMR recording technologies improve areal efficiency and signal integrity, helping the 0B48717 maintain performance consistency as capacity scales within the same 3.5in footprint.

Why Choose the 0B48717?

The 0B48717 delivers a pragmatic density-to-watt profile for enterprise capacity expansion while sustaining fleet-grade reliability for always-on environments. With TCG Enterprise SSC Self-Encrypting Drive (SED) hardware encryption, the 0B48717 supports security compliance objectives without consuming host CPU cycles, enabling scalable deployments across large SATA domains.

WD designs Ultrastar data center HDDs with an emphasis on predictable thermals, vibration tolerance in multi-bay systems, and qualification paths aligned to modern storage controllers. For fleet operators, the 0B48717 offers an enterprise reliability model with 2.5M hours MTBF and power characteristics optimized for high-count drive shelves.
