## Long description

Internal 3.5" 12G SAS HDD HP 4TB 7200 RPM is an enterprise-class 3.5-inch hard drive offering 4 TB of formatted capacity, a 7200 RPM spindle speed and a 12 Gbit/s SAS interface. Designed for server and storage array use, this drive provides high-capacity block storage suitable for databases, virtualization, backup and archival workloads and works with SAS controllers and RAID configurations.
Advantages
The drive delivers enterprise-grade reliability and performance for transaction-heavy and storage-driven applications. A dual-port SAS interface enables full-duplex data transfer and high availability. It is available in common hot-plug and non-hot-plug carriers and supports 4KiB-aligned operating systems via 512e advanced format while maintaining compatibility with legacy 512-byte applications.
Suitable for
Database servers and OLTP systems
Virtualization hosts and hyperconverged systems
Backup, archival and cold storage pools
High-capacity storage arrays and RAID configurations
When it may not be suitable
This 3.5-inch 7200 RPM SAS HDD is optimized for capacity and sustained throughput rather than the lowest possible latency or the highest IOPS. It may not be the best choice for workloads that require ultra-low latency or very high random I/O performance, such as certain high-frequency trading or extreme OLTP workloads where NVMe SSDs are typically preferred.
Key specifications
Form factor: 3.5-inch (Large Form Factor)
Capacity: 4000 GB
Rotational speed: 7200 RPM
Interface: 12 Gbit/s SAS (dual-port, full duplex)
Advanced format: 512e (4KiB physical, 512-byte emulation)
Intended use: Server/workstation enterprise HDD
How to use
Install the drive into a compatible 3.5-inch SAS drive bay or enclosure following the server or storage array vendor instructions. Configure the SAS controller and, if required, create or join a RAID array using the controller firmware or management software. Ensure firmware and driver compatibility with your server platform and perform secure initialization or wiping if deploying in a production environment.
What to consider before purchase
Confirm server or enclosure compatibility with 3.5" SAS drives and 12 Gbit/s SAS controllers.
Verify that the desired RAID controller supports 512e advanced format if specific alignment is required.
Plan for appropriate cooling and power for 3.5" 7200 RPM drives in your chassis.
Assess workload I/O profile to determine whether HDD performance meets latency and IOPS needs or if SSDs are necessary.
Usage recommendations
Use this 4 TB 12G SAS 3.5" HDD in storage tiers where capacity and sustained throughput are primary requirements—such as bulk storage, backups, archives and large database tables—while pairing with faster SSD tiers for latency-sensitive data and ensuring proper RAID configuration and alignment for reliability.
