WD 16TB UltraStar DC HC550 7200 rpm SAS-3 3.5″ Internal HDD-0F38357

Specification

Description

The WD 16TB Ultrastar DC HC550 SAS-3 Internal Data Center HDD (0F38357) is a high-capacity enterprise hard drive purpose-built to lower total cost of ownership (TCO) and maximize storage density for public and private cloud environments where cost-efficient infrastructure is critical. As part of WD’s DC HC500 series, the 16TB HC550 was among the first commercial implementations of Energy-Assisted Magnetic Recording (EAMR) technology and utilizes the industry’s first Triple-Stage Actuator design.

Built on a helium-sealed (HelioSeal) 9-disk platform in a 3.5-inch form factor, the drive uses a 12Gb/s SAS-3 interface, spins at 7,200 RPM, and features a substantial 512MB cache buffer built on Media Cache Plus architecture for improved random write performance and better response times. This combination delivers sustained transfer rates of up to 262 MB/s, with ample capacity to store millions of images, hundreds of hours of video, or up to a million songs.

The Triple-Stage Actuator, combined with Two-Dimensional Magnetic Recording (TDMR) technology, provides more accurate head positioning — especially valuable in multi-drive environments — for better performance and data integrity. Rotational Vibration Safeguard (RVS) technology maintains consistent drive performance in high-vibration, multi-drive rack environments, while Dual Safe, RSA-signed firmware retains the previous firmware version during updates, verified by an RSA signature, for safer firmware management in production environments.

Notably, the HC550 delivers 21% lower idle watts-per-terabyte compared to prior-generation 16TB helium-filled Ultrastar drives, helping data centers reduce power and cooling costs at scale. Reliability is rated at an unsurpassed 2.5 million hour MTBF with a 0.35% annualized failure rate (AFR) — among the best in class for capacity enterprise HDDs — and a workload rating of up to 550TB per year.

Backed by a 5-year limited warranty, the Western Digital Ultrastar DC HC550 16TB is engineered to drive down TCO for hyperscale and cloud data centers facing relentless data growth.

User Experience in Bangladesh

In Bangladesh, the WD 16TB Ultrastar DC HC550 SAS-3 Data Center HDD has become a trusted choice among the country’s major data centers, cloud service providers, telecom operators, and large enterprise IT departments across Dhaka, Chattogram, and other major commercial centers that require SAS-based enterprise storage for high-density, high-performance server and storage array deployments. As Bangladesh’s data center and cloud infrastructure sector continues to mature, the HC550’s SAS-3 interface makes it a natural fit for enterprise-grade servers and storage arrays that specifically require SAS connectivity rather than SATA.

Local data center operators and enterprise IT teams particularly value the drive’s HelioSeal helium-sealed design and its notably lower idle power consumption compared to earlier-generation helium drives — a meaningful advantage for Bangladeshi data centers managing electricity and cooling costs in the country’s warmer climate. The Triple-Stage Actuator and Rotational Vibration Safeguard (RVS) technologies are especially relevant for the dense, multi-drive SAS RAID arrays common in large Bangladeshi enterprise server rooms and colocation facilities.

For businesses running mission-critical cloud storage platforms, enterprise servers, or large-scale RAID arrays, the drive’s 550TB/year workload rating, 2.5 million hour MTBF, and low 0.35% AFR provide strong assurance for continuous, business-critical operations — important for Bangladeshi banks, telecom operators, and hosting providers where storage reliability directly impacts service availability. Given the country’s variable power infrastructure, enterprises deploying this drive typically pair it with robust UPS and generator backup systems to complement its enterprise-grade reliability.

The extended 5-year manufacturer warranty offers meaningful assurance for Bangladeshi organizations making substantial SAS enterprise storage investments. Combined with proven compatibility across SAS-based enterprise servers and storage arrays, the WD Ultrastar DC HC550 16TB has established itself as a dependable, high-capacity choice for Bangladesh’s growing SAS-based data center infrastructure.
