HPE 873359-B21 400GB SAS 12G 2.5″ SSD

HPE 873359-B21 400GB SAS 12G 2.5in SSD

When a ProLiant server needs fast, durable flash for demanding write workloads, a 400GB 12G SAS SSD is often the right tool, and the HPE 873359-B21 fills that role as a factory option kit. Euroland IT Store carries 873359-B21 in new and refurbished condition, with UK stock ready for next-day dispatch and worldwide shipping for international buyers.

The value of this drive lies in its interface and build. SAS 12G doubles the per-lane bandwidth of SATA 6G, adds dual-port redundancy and handles deep queues gracefully, so HPE 873359-B21 keeps latency consistent when a database or virtual machine cluster pushes sustained random I/O at it. At 400GB, it is sized for transaction logs, tempdb volumes, message queues, caching layers and OS boot mirrors, jobs where you want dependable flash endurance rather than bulk capacity.

Because this is a genuine HPE option kit from our range of HPE parts, the drive ships in the correct hot-plug carrier, runs HPE firmware and integrates fully with Smart Array controllers, iLO alerting and Smart Storage Administrator. Administrators replacing or expanding arrays can also cross-reference the maintenance spare 873566-001, which is the same drive supplied under the service part number, useful when matching what is already installed in the chassis.

We supply single drives to clear urgent failures and multi-drive quantities for new array builds. Refurbished stock is fully tested before dispatch and priced to make server upgrades affordable; new stock is available where your procurement rules require it. If you are unsure which variant your server takes, send us the serial number and we will confirm before you order 873359-B21.

Benefits

Choosing the right drive class saves money twice: once at purchase, because you are not paying for capacity you do not need, and again in service, because SAS flash endurance means fewer replacements over the server’s life. An exact-match HPE drive also protects your arrays, joining existing logical volumes cleanly and keeping firmware behaviour consistent across bays.

Our refurbished 873359-B21 drives go through testing before dispatch and typically undercut new list pricing by a wide margin, while new units remain available for contract-driven purchases. That flexibility suits everyone from MSPs maintaining client servers to IT departments stretching budgets.

The service spare version of this drive is the HPE 873566-001 400GB SAS 12G SSD, and the sibling option kit HPE 873351-B21 400GB SAS 12G SFF SSD covers the alternative configuration. For newer platforms consider the HPE P22585-001 400GB SAS 12G WI SSD. Browse more in our SSD hard drives category.
