The HPE 400GB SAS 12G Mixed Use SFF (2.5in) SC SSD (SKU: 822555-B21) is an enterprise-grade solid-state drive optimized for mixed workloads, delivering high IOPS and low latency in a small form factor.
This SSD is fully compatible with HPE ProLiant Gen8 and later servers, including DL, ML and BL lines, when used in SAS 12G backplanes.
“Mixed Use” indicates the drive is optimized for both read-intensive and write-intensive applications, offering balanced endurance and performance for virtualized and database workloads.
The SSD uses a 2.5-inch small form factor (SFF) and a 12Gb/s SAS interface for enterprise-class connectivity and hot-swap capability.
It delivers up to 2,100 MB/s sequential read, 1,250 MB/s sequential write and sustained 29K read/12K write IOPS for mixed-use workloads.
The drive offers up to 1 DWPD (drive writes per day) over a 3-year warranty period, supporting heavy mixed workload cycles.
HPE provides a 3-year, parts-only limited warranty, covering hardware failures when used in supported HPE server environments.
Simply slide the drive into any empty 2.5″ SAS 12G hot-swap bay on a compatible HPE ProLiant server and follow the server’s iLO or system BIOS prompts to configure.
Yes, it supports hardware RAID levels 0, 1, 5, 6 and 10 when paired with HPE Smart Array controllers for enhanced data protection and performance.
With enterprise-grade components, advanced error correction and an MTBF of 2 million hours, it ensures high availability and data integrity.
Yes, HPE issues periodic firmware updates via Service Pack for ProLiant (SPP) to optimize compatibility, performance and security.
Ideal workloads include virtualization, OLTP databases, data analytics and mid-tier storage where balanced read/write performance is critical.
Typical power draw is 5.5 W active and 2 W idle, helping to reduce overall data center energy usage.
By delivering higher IOPS per watt and reducing latency, it increases server consolidation ratios and lowers cooling costs.
Hot-swap the old drive: remove it from the SAS bay, insert the new SSD, then rebuild or resync via your server’s RAID management utility or OS disk tools.
You can order through authorized HPE channels or partners; post-purchase support is available via HPE Support Center and HPE Care Pack options.
