The Seagate ST900MP0026 is a 900GB, 2.5-inch enterprise hard disk drive from the Seagate Exos 15E900 family. Operating at 15,000RPM, it is designed for compatible enterprise servers and storage systems that prioritize fast data access and high input/output performance.
This model uses a dual-port SAS 12Gb/s interface and provides 256MB of cache. The exact part number, ST900MP0026, identifies the Instant Secure Erase (ISE) version with 512-byte native sector formatting. ISE is a drive security feature intended to facilitate secure erasure; it should not be confused with the separate self-encrypting-drive (SED) variants.

Compatibility Information
The ST900MP0026 requires a compatible SAS controller, SAS backplane, or enterprise storage enclosure. It is not a SATA drive and should not be selected for a SATA-only connection. Confirm that the host system supports 2.5-inch SAS drives, 900GB capacity, and 512n sector formatting. If using ISE functionality, verify that the system and its management tools support the required security workflow.
Frequently Asked Questions
1. What is the capacity of the Seagate ST900MP0026?
The drive has a nominal capacity of 900GB.
2. Is the ST900MP0026 a SATA or SAS drive?
It is a dual-port SAS 12Gb/s enterprise drive, not a SATA drive.
3. What is the spindle speed?
The ST900MP0026 operates at 15,000RPM and has an average rotational latency of 2.0ms.
4. What does ISE mean for this model?
ISE stands for Instant Secure Erase. It is a drive security feature designed to facilitate secure erasure when used with supported systems and procedures. It is distinct from the separate SED model variant.
5. Does this drive use 512n or 512e sectors?
The ST900MP0026 is the 512n native-sector version. Check the server or storage controller's sector-format requirements before installation.
6. Is the drive compatible with any server?
No. Compatibility depends on the server or storage array's SAS controller, backplane, drive form factor, firmware, and sector-format support. Check the system manufacturer's compatibility documentation before purchasing.
DC Supplies Product Note
