HPE 873363-B21 800GB SAS 12G SFF 2.5 SSD

HPE 873363-B21 800GB SAS 12G SFF 2.5in SSD

The HPE 873363-B21 pairs an 800GB capacity with a 12G SAS interface in a 2.5 inch hot-plug form factor, giving ProLiant servers a flash tier that balances working space with serious I/O capability. Euroland IT Store supplies this option kit drive new and refurbished, with stock held in the UK for fast delivery to IT departments, integrators and resellers.

At 800GB, HPE 873363-B21 doubles the space of the 400GB drives in the same family, which makes it a strong candidate for busy database volumes, virtual machine storage where write activity is significant, and application servers that outgrow smaller flash devices. The dual-ported SAS 12G interface maintains throughput and latency under concurrent load, and solid state design removes seek and rotational delays entirely, so storage stops being the bottleneck in most mid-range server configurations.

This drive is supplied as a genuine HPE option kit: correct carrier, HPE firmware, and full recognition by Smart Array controllers and iLO management. That authenticity matters in production, where an unqualified drive can generate persistent warnings or complicate a support case. The matching maintenance spare is 873569-001, so if you are replacing a failed unit originally fitted at the factory, either number will land you the same physical drive.

We ship 873363-B21 as single units or in quantity for array builds. Refurbished drives are tested before dispatch and represent excellent value for organisations extending the life of Gen8 to Gen10 estates; new stock is available for buyers who need it. Quotes are quick by phone or email, and we are happy to sanity-check compatibility against your server serial number first.

Benefits

An 800GB SAS SSD hits a practical balance point: enough capacity to consolidate performance-sensitive data onto one tier, with the endurance and consistency SAS flash is known for. Fitting the genuine HPE part keeps array behaviour predictable, from firmware updates through to rebuild times, and protects you from the compatibility surprises grey-market drives can introduce.

Cost is the other half of the story. Refurbished 873363-B21 units are tested and warranted by us at prices that make flash upgrades viable on tight budgets, while new drives remain available for projects that specify unused hardware. Many customers buy an extra drive as a cold spare, which is far cheaper than emergency freight later.

If you are matching part numbers, the service spare version is the HPE 873569-001 800GB SAS 12G SFF SSD. Comparable 800GB write-focused options include the HPE P04543-B21 800GB SAS 12G WI SSD and the HPE P26372-B21 800GB SAS 12G WI SSD. See the wider range in our server SSD drives category.
