Description

The HPE P53553-B21 is a **20TB SAS 12Gb/s Business Critical Helium HDD** designed for demanding enterprise and data center storage environments. Spinning at 7200 RPM in a 3.5-inch Large Form Factor (LFF) with Low-Profile Carrier (LPc), this drive provides both high capacity and reliable performance. It includes **Instant Secure Erase (ISE)** to securely clear data, making it ideal for sensitive workloads.

Built with a **512e sector format** and Multi-Vendor compatibility, this drive supports a broad range of HPE ProLiant and Apollo servers (Gen10, Gen10 Plus, Gen11) with support for SAS backplanes. Thanks to its helium fill and Business Critical class rating, it offers improved power efficiency and lower turbulence, compared to air-filled counterparts.

This drive also features hot-swap capability, and comes with a 1-year warranty under HPE’s Business Critical drive program. It is suitable for both archival storage and active workloads—especially when cost per TB is key, but you still need consistent, reliable throughput and security features. The nominal data transfer rate reaches up to ~1.2 GB/s in sustained sequential operations.

For organizations seeking to buy HPE 20TB SAS drives, the P53553-B21 model offers strong value: capacity, endurance, low power draw, secure erase, and compatibility with common HPE server storage architectures. It is a solid fit for backup, cold/hot-tier storage, large file repositories, surveillance, or media archives.

Compatibility

The HPE P53553-B21 drive is fully compatible with HPE Proliant Gen10, Gen10 Plus, and Gen11 servers that accept 3.5-inch LFF Low Profile Carrier (LPc) SAS drives. It fits standard drive bays in server or storage enclosures designed for SAS 12G backplanes. Hot-swap bays are supported, enabling insertion/removal without shutting down the entire system.

Firmware and system BIOS must support the 12G SAS interface and advanced format (512e). When used in RAID controllers or storage arrays, ensure that the controller supports Business Critical drives and Verifies drive health via HPE Smart Array or similar tools.

Operating temperature, power, and cooling considerations are key: helium drives are more sensitive to thermal management; ensure airflow and ambient conditions are within rated limits to maintain reliability.

Usage Scenarios

1) Cold or Bulk Storage Tiers: As part of large scale storage clusters, this drive is well suited for archival / cold storage where data is infrequently accessed but must remain online. The capacity and low idle power make it a cost-effective choice for such tiers.

2) Backup / Snapshot / Logging Repositories: Use in backup systems, snapshot stores, or log retention that require high capacity and secure erase capabilities—especially in compliance environments where data must be securely wiped. Instant Secure Erase

3) Media / Content Libraries: For video, audio, large media files, or surveillance footage archives, where large file storage and sequential IO are more important than ultra-low latency.

4) RAID Arrays for Nearline Data Access: Use in RAID-6 or RAID-Z configurations for nearline storage—balancing redundancy and usable capacity. Business Critical drives help ensure reliability under rebuild or failure scenarios.

5) Server Storage Expansion: When upgrading or expanding storage in HPE servers or Apollo systems with LPc drive bays—this drive allows large expansion with fewer physical drives, helping reduce overhead and simplify management.

Frequently Asked Questions

  1. Q: What is the difference between Helium-sealed Business Critical drives and standard glass-sealed or air drives?
    A: Helium-sealed drives displace air with helium, which reduces internal turbulence and friction—this leads to lower power draw, cooler operation, and often better reliability for large capacity HDDs especially under sustained load. The P53553-B21 uses Helium and is categorized as Business Critical to reflect higher durability and reliability standards.
  2. Q: How much usable storage will I get if I use this drive in a RAID-6 array with two parity drives?
    A: If used in a large RAID-6 array, you will lose capacity equal to the number of parity drives; for example, in a 10-drive RAID-6 set, two drives are parity, so usable capacity = (n-2)/n × total raw capacity. With 20TB drives, each additional drive adds 20TB raw, but usable depends on array size and overhead.
  3. Q: Is this drive suitable for high IOPS workloads or mostly for sequential throughput?
    A: While 7200 RPM SAS drives provide decent performance, they are more optimized for sequential throughput and bulk data than extremely latency-sensitive workloads. For heavy IOPS (random small‐block read/write), SSDs or higher RPM SAS drives might perform better. This model shines in capacity, cost-per-TB, and moderate performance tasks.
  4. Q: What are the power and thermal requirements for using this drive in a server chassis?
    A: Helium drives tend to run cooler but still require adequate airflow. Ensure the chassis supports LPc 3.5” bays and that SAS backplanes and controllers are compatible with 12G SAS. Also verify that power supplies and thermal management in the server can handle drive load especially during rebuilds or heavy sequential usage.
