About the Seagate Exos 7E10 4TB 7200RPM 3.5-inch SAS HDD
The Seagate Exos 7E10 4TB (ST4000NM025A) is a 3.5-inch enterprise-class hard drive engineered for high-density data center deployments, delivering sustained 7200 RPM performance across demanding 24×7 workloads. Built on Seagate's mature perpendicular magnetic recording architecture and paired with a dual-port SAS 12Gb/s interface, this drive provides the throughput consistency and protocol reliability required in enterprise storage arrays, RAID enclosures, and server-attached storage environments. Its 512n sector format ensures broad compatibility with legacy and current-generation storage controllers.
Designed for enterprise reliability, the Exos 7E10 4TB is rated for up to 550TB per year workload, a specification that reflects its suitability for write-intensive sequential and random I/O profiles alike. The drive incorporates Seagate's PowerChoice technology for configurable power states and PowerBalance technology to optimize the trade-off between random I/O performance and power consumption, making it an operationally efficient choice for large-scale storage builds where thermal and power budgets are tightly managed.
With a 256MB cache buffer and support for dual-port SAS connectivity, the ST4000NM025A is particularly well-suited for environments requiring high availability and multi-path I/O configurations. Seagate's Secure cryptographic erase capability and optional self-encrypting drive variants position the Exos 7E10 family within compliance-sensitive deployments. The drive's enterprise-grade vibration compensation (RVCM) ensures consistent performance when deployed in multi-drive chassis alongside dozens of other spinning drives.
Ideal for
- High-density block storage arrays in hyperscale and enterprise data centers requiring sustained 24×7 throughput
- RAID and JBOD expansion shelves in SAN and DAS configurations where dual-port SAS multipath failover is required
- AI and machine learning training infrastructure storage tiers handling large sequential dataset reads and checkpoint writes
- Backup and archival targets in tape-replacement workflows demanding high workload ratings and long operational duty cycles
- Video surveillance and media asset repositories requiring continuous write performance across high-drive-count enclosures
- Nearline storage tiers in tiered storage architectures serving cold and warm data within cloud and co-location environments across UAE, GCC, EMEA, and APAC regions

Frequently Asked Questions about Seagate Exos 7E10 4TB 7200RPM 3.5-inch SAS HDD
What workloads is the Seagate Exos 7E10 4TB 7200RPM 3.5-inch SAS HDD designed for?
Enterprise mixed-use and read-intensive 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.
