HPE 1.8TB SAS 12Gb/s 15000RPM Mission Critical 2.5-inch Hard Drive with Basic Carrier — P53562-B21

The HPE P53562-B21 is a 1.8TB SAS 12Gb/s 15000RPM Mission Critical (MC) 2.5-inch Small Form Factor (SFF) hard disk drive with HPE Basic Carrier, designed and validated for HPE ProLiant servers. As a digitally signed HPE drive, it is cryptographically authenticated by the server’s firmware for security and compatibility. The Mission Critical designation and 15,000RPM spindle speed make it the highest-performance HDD class available — delivering the lowest latency and highest IOPS of any spinning disk. Ideal for performance-sensitive enterprise workloads including OLTP databases, virtualization datastores, and high-frequency transactional applications where SSD cost is prohibitive but maximum HDD performance is required.

Use Cases

• OLTP databases — Oracle, SQL Server, SAP HANA requiring maximum HDD IOPS and lowest latency
• Virtualization datastores — high-performance VM storage for VMware vSphere and Hyper-V
• High-frequency transactional applications — ERP, CRM, financial trading platforms
• SAN and DAS storage — high-performance primary storage tiers in HPE MSA and 3PAR/Primera arrays
• Email and collaboration servers — Microsoft Exchange, SharePoint requiring high random I/O
• Performance-tier storage — top tier in tiered storage configurations where SSD is cost-prohibitive

Ordering Notes

• P53562-B21 is an HPE option part number — verify spare part number with HPE QuickSpecs for service procurement
• Digitally signed — will not function in non-HPE servers or HPE servers with unsigned drive restrictions disabled
• Mission Critical endurance — 15K RPM drives are ideal for heavy random I/O; use Midline drives for bulk sequential/archival workloads
• Verify compatibility via HPE SPOCK or server QuickSpecs for your specific ProLiant model and Smart Array controller
