Description
Western Digital Ultrastar DC HC555 14TB EAMR HelioSeal 3.5″ SATA 6Gb/s 7200RPM 512MB Cache 512e Internal HDD
0B48721
High-capacity, data-center grade 14TB drive optimized for 24×7 operation. The Ultrastar DC HC555 (part 0B48721) combines EAMR CMR recording, HelioSeal efficiency and a large 512MB cache to deliver up to ~269MB/s sustained transfers on a 7200RPM spindle—ideal for NAS, surveillance backends, backup targets and bulk content storage.
Why it’s a good choice
-
Max density per bay: 14TB per 3.5″ slot reduces chassis count and TCO for backup and media libraries.
-
Consistent performance: 7200RPM + 512MB cache and ~269MB/s sustained transfers handle large sequential jobs and fast rebuilds.
-
Built for 24×7 fleets: Ultrastar HC555 lineage targets data-center workloads and high reliability under continuous use.
-
Cooler, quieter racks: HelioSeal helium design cuts internal drag for lower power and temperatures—great for dense enclosures.
-
Standards-friendly integration: SATA 6Gb/s and 512e Advanced Format drop into modern servers, JBODs and NAS with minimal tuning.
-
Future-ready media tech: EAMR CMR improves areal density without SMR compromises—better for RAID and multi-user I/O.
