The Seagate ST30000NM004K is a 30TB enterprise-class hard disk drive from the Exos M family. Designed for high-capacity data storage, this 3.5-inch drive combines a 7200RPM rotational speed, SATA 6Gb/s interface, and 512MB cache in a helium-sealed design.
Using conventional magnetic recording (CMR), the drive is intended for compatible enterprise storage environments that require high capacity and sustained data-transfer performance. The ST30000NM004K is the standard instant secure erase (ISE) model with a 512e sector format.
Key Features
- 30TB storage capacity: Provides high-density storage for large datasets, business applications, archives, and backup repositories.
- 7200RPM spindle speed: Supports enterprise storage workloads requiring consistent mechanical disk performance.
- SATA 6Gb/s interface: Connects to compatible SATA controllers and enterprise storage systems.
- 512MB cache: Provides a large onboard buffer to support drive operations and data transfers.
- CMR recording technology: Uses conventional magnetic recording for compatible enterprise storage applications.
Enterprise Storage Applications
The Exos M ST30000NM004K is designed for high-capacity storage infrastructure, including enterprise servers, data centers, and compatible storage arrays. Its large capacity can help increase storage density while reducing the number of drives required for a given storage target.
Before installation, verify that your system supports 30TB drives, SATA connectivity, and the 512e sector format. Confirm controller, firmware, operating system, and enclosure compatibility, particularly when deploying the drive in an existing storage array.

Frequently Asked Questions
What is the capacity of the Seagate ST30000NM004K?
This model provides 30TB of nominal storage capacity.
Is the ST30000NM004K a SATA or SAS drive?
It uses a SATA 6Gb/s interface. Confirm that your server or storage enclosure supports SATA drives rather than requiring SAS-only models.
How much cache does this drive have?
The ST30000NM004K includes a 512MB cache buffer.
What does 512e mean?
512e means the drive presents 512-byte logical sectors while using 4K physical sectors. Check that your controller and operating system support this format.
What is Instant Secure Erase?
Instant Secure Erase is a drive security feature designed to facilitate secure erasure of stored data. Its use and supported procedures depend on the drive configuration and applicable documentation.
