The Western Digital 2TB Ultrastar DC HA200 SATA HDD belongs to the company’s data center hard drive family, engineered for continuous operation in enterprise storage environments. This 3.5-inch unit uses a 7200 RPM spindle speed and a SATA 6 Gb/s interface, paired with a 128 MB cache buffer to manage data transfers efficiently. The drive is built around conventional magnetic recording (CMR) technology, which provides predictable read and write performance for workloads that require consistent latency. Its firmware is optimized for high reliability under sustained usage, making it suitable for servers, network-attached storage (NAS) arrays, and surveillance systems that run around the clock. The construction features a robust chassis that helps dissipate heat, while the sealed head-disk assembly reduces the risk of contamination during operation. From a hardware standpoint, the Ultrastar DC HA200 incorporates a dual-stage actuator head positioning system that improves track-following accuracy, contributing to stable performance even under vibration. The drive’s average latency is approximately 4.16 ms, with a sustained transfer rate reaching up to 215 MB/s. Power consumption is kept moderate, with typical idle draw below 5.5 watts and active load around 7.0 watts, which helps in managing thermal output in dense storage arrays. The 2 TB capacity offers a balance between density and cost, accommodating sizable data sets such as backup archives, media libraries, or virtual machine storage. Error correction and shock protection mechanisms are integrated to maintain data integrity during unexpected power events or physical disturbances. Reliability is a core focus of this model. The Ultrastar DC series is rated for an annualized failure rate (AFR) of less than 0.5% under typical data center conditions, and the drive supports a workload rate of up to 550 TB per year. The mean time between failures (MTBF) is rated at 2 million hours, and the product undergoes rigorous qualification testing including thermal cycling and vibration exposure. The self-encrypting drive (SED) option is available in some variants, though this standard model relies on hardware-based write caching to optimize random I/O operations. For users who require consistent performance without the overhead of shingled magnetic recording, the CMR architecture ensures that overwrite operations do not suffer from write amplification, making it a straightforward choice for RAID setups. In terms of value, the presented price of $166.97 positions this 2 TB enterprise HDD as a cost-effective option for upgrading storage infrastructure where reliability matters. It competes with consumer-grade drives but offers a longer warranty period and tighter quality controls typical of data center components. The drive is backward compatible with SATA II ports, though maximum throughput is achieved when connected to a SATA III host. Its form factor (3.5 inches) allows direct replacement in most standard bays, and the low acoustic noise profile makes it viable for office or home server environments.

This hard drive delivers dependable performance for users who prioritize data security and longevity over peak sequential speeds.
