HPE VO001920RWUFE 1.92TB SSD

The HPE VO001920RWUFE 1.92TB SAS 12G Mixed Use SFF SC Value SAS Solid State Drive represents a cornerstone of HPE's storage strategy for modern data centers. This drive is meticulously designed to deliver a balance of performance, endurance, and unwavering reliability specifically within the HPE ProLiant server ecosystem. As a Value SAS model, it provides a critical price-to-performance point, offering superior speed and latency over SATA SSDs while maintaining the robust feature set and management integration expected from genuine HPE components. The 1.92TB capacity in the 2.5-inch Small Form Factor (SFF) makes it an ideal choice for a wide array of applications, from virtualized environments and databases to general-purpose server boot and storage volumes, where consistent mixed read/write performance is paramount.

Key Specifications 

Understanding the detailed specifications of the HPE VO001920RWUFE SSD is essential for proper integration and performance planning within your server infrastructure. This section provides a comprehensive breakdown of the drive's technical attributes, from its interface and form factor to its raw performance metrics and environmental tolerances.

Physical Attributes

The product is formally identified by the part number VO001920RWUFE. This alphanumeric code is crucial for ensuring part compatibility and for sourcing genuine HPE components. The drive features a 2.5-inch Small Form Factor (SFF) design with a height of 15mm, which is a standard size for most ProLiant server drive bays. Its weight is optimized for server environments, typically around 100 grams, ensuring secure mounting and minimal vibration.

Detailed Capacity and NAND Flash Information

The drive offers a formatted capacity of 1.92 Terabytes (TB). This specific capacity point is common in enterprise SSDs as it provides a significant amount of user-accessible space while the drive's internal controller reserves a portion of the raw NAND for over-provisioning. This over-provisioning is a critical technique for enhancing the drive's endurance, garbage collection efficiency, and consistent write performance over its entire lifespan. The drive utilizes high-quality, enterprise-grade Multi-Level Cell (MLC) or TLC NAND flash memory (specific to the generation), chosen for its optimal balance of cost, endurance, and performance.

Interface, Protocol, and Performance Benchmarks

This SSD is equipped with a SAS (Serial Attached SCSI) 12Gb/s interface, which is double the bandwidth of the previous 6Gb/s generation. The SAS interface provides full-duplex communication, meaning it can read and write data simultaneously at up to 12Gb/s on each port. The drive supports dual-port functionality, a key high-availability feature that allows it to be connected to two separate host controllers simultaneously. This provides redundant paths to the data, ensuring that if one controller or path fails, the other can maintain uninterrupted access to the drive—a non-negotiable requirement for mission-critical applications.

Sustained Read and Write Performance

As a Mixed Use drive, the VO001920RWUFE is engineered to handle a balanced workload of both read and write operations. It delivers sustained sequential read speeds of up to 1,800 MB/s and sustained sequential write speeds of up to 1,000 MB/s. For random I/O, which is more representative of real-world database and virtualization workloads, it can achieve up to 250,000 IOPS (Input/Output Operations Per Second) for random reads and up to 65,000 IOPS for random writes. These performance figures are typically measured with a 4KB block size and a queue depth sufficient to saturate the drive's capabilities.

Endurance and Reliability

Enterprise SSDs are defined not just by their speed, but by their ability to perform reliably under constant write pressure. The endurance of an SSD is measured by the total amount of data that can be written to it over its lifetime, a metric known as Terabytes Written (TBW) or Drive Writes Per Day (DWPD).

Mixed Use Workload Endurance 

The "Mixed Use" classification signifies that this drive is built for workloads that consist of a moderate to heavy mix of read and write operations, typically around a 50/50 split. The HPE VO001920RWUFE 1.92TB SSD is rated for a high TBW value. This headroom is vital for ensuring performance consistency and data integrity even under demanding conditions.

Firmware and HPE Ecosystem Integration

One of the most significant advantages of using this genuine HPE drive is its deep integration with the HPE ProLiant server ecosystem. This integration is primarily managed through the drive's firmware, which is specifically tuned and validated for HPE servers.

Digitally Signed Firmware for Enhanced Security

The HPE VO001920RWUFE features Digitally Signed Firmware. This is a critical security measure that ensures the firmware running on the drive is an authentic, unaltered version released by HPE. Before loading any firmware update, the drive's bootloader verifies the digital signature. If the firmware is not signed by HPE's private key, it will be rejected, preventing the installation of malicious or unvalidated firmware that could compromise performance, stability, or data security. This protects against a class of attacks aimed at the device's firmware level.

Seamless Management with HPE iLO and HPE SSM

The drive is fully manageable through HPE Integrated Lights-Out (iLO) management controllers and the HPE System Software Manager (SSM). This allows administrators to monitor drive health, temperature, remaining endurance, and SMART status remotely from a single pane of glass. Firmware updates for the drive are delivered through HPE's Service Pack for ProLiant (SPP), ensuring that updates are tested, certified, and deployed in a coordinated manner with the rest of the server's firmware and drivers, eliminating compatibility issues and simplifying lifecycle management.

Compatibility and Supported Server Platforms

The HPE VO001920RWUFE is explicitly validated and certified for use in HPE ProLiant Gen9 and Gen10 servers. This includes a wide range of models from the DL, ML, and BL families that support SFF SAS drives.

Optimized for ProLiant Gen9 and Gen10 Architectures

In Gen9 and Gen10 servers, this drive works seamlessly with HPE Smart Array controllers (e.g., P408i, P816i) and HPE HBA controllers. The drive's power-on and initialization sequences are timed to work optimally with the ProLiant platform, ensuring reliable booting and stable operation. Using this drive in a supported ProLiant server ensures that you receive the full performance profile and that all advanced data protection features are active and managed by the server's ecosystem.

Ideal Use Cases and Application Workloads

The performance and endurance characteristics of this Mixed Use SSD make it suitable for a broad spectrum of enterprise applications. It is an excellent choice for server boot drives, significantly reducing OS and application boot times compared to HDDs. It is perfectly suited for hosting virtual machine disks in hypervisors like VMware vSphere or Microsoft Hyper-V, where the low latency and high IOPS improve virtual machine density and responsiveness. It can also handle database workloads (e.g., Microsoft SQL Server, MySQL) for mid-tier applications, journaling filesystems, and read-intensive caching layers.

Advanced Features and Data Integrity

Beyond raw performance, the HPE Value SAS SSD incorporates a suite of advanced features designed to protect data and maximize drive longevity.

Power Loss Protection and Data Caching

A critical feature in any enterprise SSD is protection against sudden power loss. The VO001920RWUFE incorporates advanced power-loss circuitry, often involving capacitors. In the event of an unexpected power failure, this system provides enough hold-up energy to flush all data held in the volatile DRAM write cache to the non-volatile NAND flash. This prevents data corruption and ensures that all acknowledged writes are permanently stored, a fundamental requirement for transactional data integrity.
