The HPE 800GB SATA 6G Write Intensive LFF SSD (SKU 831725-B21) is a high-performance, 3.5-inch solid-state drive designed for write-intensive workloads in Gen8 and later HPE servers.
The SSD is certified for Gen8, Gen9, Gen10 and beyond HPE ProLiant and BladeSystem servers that support SATA 6Gb/s LFF drives.
It delivers sequential read speeds up to 550 MB/s and sequential write speeds up to 520 MB/s, ensuring fast data access and consistent throughput for write-heavy applications.
“Write Intensive” indicates the drive is engineered for high endurance, supporting up to 30 DWPD (Drive Writes Per Day) for mission-critical, heavy-write environments.
With up to 30 DWPD endurance over its three-year warranty, the drive handles sustained write workloads reliably in enterprise settings.
Yes, it includes a three-year limited warranty covering defects in materials and workmanship when used per HPE guidelines.
Hot-swap into any compatible LFF drive bay following the server’s hardware installation guide—no tools required for most HPE caddies.
Yes, you can mix SATA SSDs, SAS SSDs and HDDs in supported drive bays, but performance tiers will remain distinct.
Typical active power draw is 6 W and idle power is approximately 3 W, helping optimize your server’s energy profile.
It uses a 3.5-inch (LFF) form factor and SATA 6 Gb/s interface, fully compatible with standard HPE LFF drive bays.
Use HPE Smart Storage Administrator or HPE Integrated Lights-Out (iLO) to track SMART attributes and drive endurance metrics in real time.
Yes, the drive supports hot-swap operations, allowing insertion or removal without powering down the server.
Ideal for databases, virtualization hosts, log processing and other write-heavy enterprise applications requiring high endurance.
Write-Intensive SSDs provide higher DWPD and more robust firmware for heavy write cycles, while Read-Optimized SSDs target read-centric workloads with lower endurance.
Yes, it is fully supported in HPE Smart Array RAID controllers, delivering reliability and data protection in RAID 0/1/5/6/10 arrays.
