About the WD Ultrastar DC HA340 8TB 3.5-inch SATA 6Gb/s 7200 RPM Enterprise Hard Drive
SATA 6Gb/s, 3.5-inch form factor with a 2,000,000-hour MTBF — the WD Ultrastar DC HA340 8TB (part number WUS721008ALE6L4) is a purpose-built enterprise hard drive engineered for high-capacity, reliable storage in demanding data center environments. Manufactured by Western Digital, this drive combines proven conventional magnetic recording technology with a 256 MB cache buffer and sustained transfer rates up to 255 MB/s, delivering consistent performance for mission-critical workloads. The 7200 RPM spindle speed and robust mechanical design, including rotational acceleration feed forward (RAFF) vibration compensation, ensure dependable operation in multi-drive systems where shock and vibration are common.
With an annualized workload rating of 550 TB/year and support for 600,000 load/unload cycles, the DC HA340 is built to handle continuous enterprise operation across storage arrays, backup appliances, and archive systems. Power efficiency remains a priority — typical idle consumption of 5.0 W and active read/write consumption of 7.2 W help reduce operational costs in large-scale deployments. The drive operates reliably across 0°C to 60°C, with a compact 26.1 mm Z-height suitable for standard 3.5-inch rackmount environments. For storage architects and IT procurement teams evaluating capacity-dense SATA solutions, Western Digital's DC HA340 offers the throughput and reliability needed in modern data centers.
Typical Enterprise Deployment Scenarios
- Mid-tier NAS and SAN storage arrays requiring 8 TB per-drive capacity and consistent 255 MB/s throughput
- Enterprise backup and archival systems operating within the 550 TB/year workload envelope
- Multi-drive RAID configurations where vibration-resistant design and high MTBF reduce unplanned downtime
- Data centers with space constraints benefiting from 3.5-inch form factor density and low power profiles
- Cloud and virtualization infrastructure requiring proven CMR recording technology and 600,000 load/unload cycle endurance

Frequently Asked Questions about WD Ultrastar DC HA340 8TB 3.5-inch SATA 6Gb/s 7200 RPM Enterprise Hard Drive
What workloads is the WD Ultrastar DC HA340 8TB 3.5-inch SATA 6Gb/s 7200 RPM Enterprise Hard Drive designed for?
Enterprise mixed-use and ri workloads — including transactional databases, AI inference data, virtualisation, hyperconverged storage, and analytics. Endurance is rated for sustained 24/7 operation, not consumer-style burst use.
Will this SSD work in my Dell / HPE / Lenovo server?
Most enterprise SSDs ship in vendor-branded variants tied to a server QVL. Share your server model and we will quote the correctly-branded SKU (Dell-genuine, HPE-genuine, Lenovo-genuine) so support and firmware update tooling work without complaints.
Do you provide support support locally?
Yes. All units are sourced through distribution, so support registers cleanly with the manufacturer (Samsung / Kioxia / Solidigm / Micron / WD / Seagate) and DOA replacement is handled through our Dubai operations within 5 business days for UAE/GCC.
How do I get a quote for a bulk order?
Use the RFQ form on this page with your quantity and destination. For larger and project-scale orders we engage the vendor directly to prepare a tailored quote, and our pre-sales team follows up with a vendor-confirmed quote.
