HPE 3.2TB SAS 12G Mixed Use SFF Smart Carrier SSD (P21135-B21)

Data-intensive workloads in enterprise servers demand storage that can keep pace without compromising endurance. The HPE 3.2TB SAS 12G Mixed Use SFF Smart Carrier SSD (P21135-B21) delivers exactly that: a high-capacity, high-performance drive engineered for mixed read/write environments. With 3.2TB of storage and a 12Gb/s SAS interface, it accelerates applications like databases, virtualization, and online transaction processing while maintaining consistent latency.

Who is it for

IT administrators and data center managers running HPE ProLiant Gen10 or Gen10 Plus servers who need reliable, high-endurance storage for mixed workloads. Ideal for businesses requiring balanced performance and capacity in a 2.5-inch small form factor.

Main features

• 3.2TB storage capacity in a 2.5-inch SFF with Smart Carrier (SC) for easy hot-plug installation.
• SAS 12Gb/s interface for high throughput and low latency.
• Mixed Use (MU) endurance: 3 drive writes per day (DWPD) for 5 years, suitable for write-intensive applications.
• Sequential read up to 1200 MB/s and write up to 1000 MB/s; random 4KB read up to 180,000 IOPS and write up to 100,000 IOPS.
• 3D Triple-Level Cell (TLC) NAND for cost-effective performance and reliability.
• Digitally signed firmware for enhanced security and integrity.
• Mean Time Between Failures (MTBF) of 2,000,000 hours for long-term reliability.
• Power consumption approximately 10-12W active, balancing performance and energy efficiency.
