About the Western Digital Ultrastar DC HC310 8TB 7200RPM SAS 12Gb/s 3.5-inch CMR Enterprise HDD
The Western Digital Ultrastar DC HC310 8TB is a 3.5-inch enterprise-class hard drive engineered for demanding datacenter and cloud-scale storage environments. Built on Conventional Magnetic Recording (CMR) technology, it delivers consistent, predictable write performance essential for mixed read/write workloads. The drive interfaces via SAS 12Gb/s, offering dual-port connectivity for high-availability configurations, and spins at 7200 RPM with a 256MB cache buffer to sustain throughput in latency-sensitive applications.
The HC310 is rated for a 2.5 million hours Mean Time Between Failures (MTBF) and supports an annual workload rating of 550TB per year, making it well-suited for 24/7 always-on datacenter operation. The SAS interface provides end-to-end data integrity protection through T10 PI (Protection Information) support, while the drive's PowerBalance technology dynamically adjusts power consumption between performance and efficiency modes. Rotational Vibration (RV) sensors and compensation circuitry ensure stable operation in multi-drive, high-density enclosures.
Designed for enterprise IT infrastructure, AI storage tiers, cloud service providers, and large-scale surveillance or backup repositories, the Ultrastar DC HC310 8TB carries manufacturer part number HUS728T8TAL5204 and is available through Omnixon Global for enterprise buyers across the UAE, GCC, EMEA, and APAC regions. Its combination of SAS dual-port reliability, CMR write consistency, and high workload endurance positions it as a proven choice for block storage arrays, JBOD expansion shelves, and tiered enterprise storage architectures.
Ideal for
- High-density SAN and NAS storage arrays requiring dual-port SAS availability and CMR write consistency
- Cloud and hyperscale datacenter bulk storage tiers handling mixed random and sequential I/O workloads
- AI and analytics data lakes where large sequential reads and sustained throughput are critical
- Enterprise backup and data protection repositories with high sustained write workload demands
- High-availability server storage with multi-drive JBOD enclosures benefiting from RV compensation
- Surveillance and media archival systems requiring continuous 24/7 write operation at scale

Frequently Asked Questions about Western Digital Ultrastar DC HC310 8TB 7200RPM SAS 12Gb/s 3.5-inch CMR Enterprise HDD
What workloads is the HGST Ultrastar DC HC310 8TB 7200RPM SAS 12Gb/s 3.5-inch CMR Enterprise HDD 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.
