HPE 875515-011 1.92TB SATA-6GBPS SFF Read Intensive SC DS SSD

HPE 875515-011 1.92TB SATA-6GBPS Overview

The HPE 875515-011 1.92TB SATA-6GBPS Read Intensive Small Form Factor (SFF) Smart Carrier DS Solid State Drive is a purpose-built server SSD optimized for large-scale read-dominant workloads. Engineered to fit HPE ProLiant and other enterprise rack servers that accept a 2.5" SFF smart carrier, this 1.92TB drive combines high capacity and low latency with a SATA 6Gb/s interface to deliver consistent sequential and random read performance for content delivery, VM boot/storage, caching tiers, analytics, and archive acceleration.

Use Cases

1. Content delivery and web front ends

For CDNs, web servers, and media libraries that predominantly serve read requests, large 1.92TB RI SSDs reduce the need for complex caching layers and maximize cache hit ratios. The HPE 875515-011 provides the capacity to host large datasets locally on servers and the low access times to keep page loads and streaming starts fast.

2. Virtual machine boot and OS images

In virtualized environments, storing frequently read boot images and golden VM templates on read-focused SSDs speeds boot storms and reduces CPU wait times, improving consolidation ratios and time-to-service for VMs.

3. Analytics, reporting, and data warehousing

Analytical queries can be IO-bound and read-heavy; placing hot, frequently accessed tables or index structures on high-capacity RI SSDs increases query throughput without the higher cost of specialized write-durable media.

Performance

While SATA as an interface is capped by the 6.0 Gb/s physical layer, a modern enterprise SATA SSD tuned for read-intensive workloads will still deliver strong sequential throughput—commonly near the SATA practical maximum—and excellent random read IOPS thanks to internal parallelism and optimized firmware. Specifications published in multiple product listings place the sequential read ceiling of similar HPE 1.92TB SATA RI SFF SSDs around the 500–540 MB/s range; random read IOPS depend on queue depth and workload pattern.

Understanding latency vs IOPS

In enterprise deployments, latency (especially at low queue depths) is the more user-perceptible metric. SSDs like the HPE 875515-011 reduce seek and rotational delays inherent to HDDs, producing consistent millisecond or sub-millisecond latencies for reads under typical production loads. For IOPS-heavy workloads with small random reads, a properly configured RAID controller and host software stack ensure the drive's max IOPS are exposed to the OS.

Compatibility

The 2.5" SFF Smart Carrier form factor and SATA interface ensure broad physical compatibility, but differences in carrier part numbers and server firmware across HPE ProLiant generations mean you should confirm compatibility before purchase. Many listings reference compatibility with G8, G9 and Gen10 platforms; always verify your exact server model, backplane type, and required carrier part number. Reseller pages and HPE support documents are a good starting point for cross-referencing part numbers.

Deployment

When deploying the HPE 875515-011 within a RAID array, consider RAID levels and rebuild times. RAID 1/10 arrays offer mirroring for read performance and redundancy, while RAID 5/6 deliver higher usable capacity but longer rebuild windows. In read-heavy environments, RAID read caching and multiple drive stripes can dramatically improve aggregate throughput; however, use a controller with SSD-aware rebuild algorithms and ensure consistent firmware across array members to minimize rebuild errors and variance. For very large arrays, consider distributing hot data across multiple SSDs to avoid single-drive hotspots.

Comparing

When sizing storage, it helps to compare this RI SATA SSD to alternatives:

RI SATA vs Mixed-Use SATA

Mixed-use drives offer higher write endurance and are better for write-heavy databases and logging, but at a higher cost per GB. The 875515-011 is more cost-effective where reads dominate.

RI SATA vs NVMe / U.2 / U.3 SSDs

NVMe SSDs deliver substantially higher IOPS and lower latency than SATA, making them ideal for ultra-low-latency databases and high-concurrency workloads. However, NVMe solutions are more expensive per GB. For large read datasets where throughput and predictable latency are important but extreme IOPS are not required, a SATA RI 1.92TB drive provides a strong price/performance tradeoff.
