Western Digital 6TB Ultrastar DC HC310 7200 RPM SATA 6.0Gb/s 3.5" Data Center Internal Hard Drive Model 0B36039 (Renewed)

WD Ultrastar DC HC310 6TB 3.5″ Enterprise SATA Hard Drive (Model 0B36039) High-Reliability, 7200 RPM, 6 Gb/s SATA – For Data Centers & RAID Arrays Product Overview: WD Ultrastar DC HC310 6TB (P/N 0B36039) is built for enterprise-grade storage environments. With 6 TB capacity, 7200 RPM spindle speed, and a 6 Gb/s SATA interface, this drive is designed to deliver the performance and durability needed for demanding server, NAS or networked storage setups. It’s part of the Ultrastar DC HC300 series, optimized for traditional IT workloads and scalable data architectures. Key Features: Reliable Data-Center Class Build — Rated for up to 2 million hours MTBF and backed by a 5-year limited warranty, making it suitable for 24×7 operation in enterprise storage systems. High Workload Rating — Designed to support annual workloads up to ~550 TB/year — far beyond typical desktop drives. Fast 7200 RPM Performance — With 7.2k RPM and an advanced dual-stage micro-actuator design, the drive delivers improved head positioning accuracy and better performance in multi-drive RAID or dense-storage environments. Advanced Cache & Format Support — Offers a 256 MB buffer (for many configurations), supports 512e or 4Kn sector formats, and features a non-volatile cache (NVC) to improve write reliability. Sustained transfer rates up to ~255 MB/s (for 512e/4Kn models). Enterprise-Ready Interface — SATA 6 Gb/s (for this model) makes integration easy with standard server/SATA controllers, while the large form factor (3.5″) aligns with typical enterprise chassis.  Backward-Friendly & Cost-Conscious — As part of the “mid-capacity” DC HC300 series, this drive offers a good balance of performance and cost for traditional IT/storage use-cases, without moving to ultra-high capacity or helium-filled designs. Ideal Use Cases: Storage arrays, RAID configurations or JBODs in server racks that require high reliability and large capacity. Direct Attached Storage (DAS) or Network Attached Storage (NAS) systems used in business/enterprise settings. Big-data, distributed file systems or archiving where consistent performance and uptime are critical. Replacement or expansion of legacy enterprise drives, especially where budget, compatibility or reliability matter.
