This article covers HGST (エイチジーエスティー) WD Ultrastar (ウルトラスター) DC HC510 8TB 7200RPM 512e SATA 6Gb 3.5インチ SE ヘリウムハードドライブ (HUH721008ALE604) (リファービッシュ品).

Overview

The HGST WD Ultrastar DC HC510 (model HUH721008ALE604) is an enterprise-grade 3.5-inch internal hard drive designed for data center and server environments. With 8TB of capacity, a 7200RPM spindle speed, and a SATA 6Gbps interface, it delivers reliable bulk storage. Its standout feature is helium-filled technology, which reduces power consumption per terabyte by approximately 43% compared to air-filled drives while maintaining high data integrity. This particular unit is sold as a refurbished product, offering significant cost savings over new drives. Originally built for 24/7 operation, it includes dual-stage micro-actuators and rotational vibration sensors for stable performance under heavy workloads. For users seeking large-capacity storage on a budget, this drive presents an attractive option.

Compatibility Guide

The drive uses the standard 3.5-inch form factor, fitting into most desktop PC cases and NAS enclosures. It connects via SATA 6Gbps and is backward compatible with SATA 3Gbps and 1.5Gbps ports, though full performance requires a 6Gbps controller. Power is supplied through a standard SATA power connector. Because it is a refurbished unit, initial testing is recommended. The drive uses 512e (512-byte emulation) sector format, which is fully supported by Windows 10/11 and modern Linux kernels (4.4+). Older operating systems like Windows 7 may require driver or firmware updates. Always verify compatibility with your specific hardware before purchase.

Product Info

The HGST WD Ultrastar DC HC510 (HUH721008ALE604) was originally released around 2017 as part of Western Digital's enterprise HDD lineup. Refurbished units remain widely available at significantly reduced prices. At the time of writing, the price on is approximately ¥73,085, though prices vary by seller. Warranty coverage for refurbished drives is typically short (30–90 days) and depends on the retailer. In the market, this drive sits in the mid-range enterprise segment, balancing reliability and cost. Helium filling enables lower power draw and higher density, making 8TB a practical size for home NAS and backup applications.

Best Use Cases

NAS and home server builders: The drive's low power consumption and 24/7 reliability make it suitable for RAID arrays. However, due to its refurbished nature, consider using multiple drives in a redundant configuration and keep a spare on hand. Budget-conscious users needing large storage: For video editing archives, backups, or media libraries, this drive offers a fraction of the cost of new 8TB HDDs. But if data is critical, invest in a new drive or maintain separate backups. Adding storage to a desktop PC: If you have a free 3.5-inch bay, this drive is easy to install. Use it for data storage alongside an SSD for the operating system. Not ideal for: Users who require maximum reliability for irreplaceable data, or those who prioritize quiet operation (7200RPM drives produce noticeable noise).

Things to Consider

Refurbished drives carry higher failure risk than new ones. Always check SMART data upon arrival and monitor for bad sectors. The helium-filled design is sealed; if a leak occurs, the drive becomes unusable. Regular backups are essential. 512e format may not be recognized by older operating systems or some NAS devices. Verify compatibility beforehand. Compared to new NAS-oriented drives like Seagate IronWolf or WD Red, this drive lacks the longer warranty and vibration optimization, but costs significantly less. Choose based on your risk tolerance and budget. ## FAQ
Q: Can I use this drive with Windows 11? A: Yes, Windows 11 natively supports 512e drives. Initialize it with GPT partition style for best results. Q: Is it suitable for NAS use? A: Yes, its enterprise design handles 24/7 operation well. However, because it's refurbished, use RAID for redundancy and perform regular health checks. Q: How much cheaper is it compared to a new 8TB HDD? A: A new 8TB NAS HDD typically costs ¥20,000–¥30,000, while this refurbished unit can be found for ¥7,000–¥15,000 depending on seller and condition. Prices fluctuate.
