HPE 10TB LFF 3.5" SATA 6G 7200 RPM 512E SC HDD

The HPE 857648-B21 is a 10TB hard disk drive designed for administrators who need to add serious capacity to an HPE ProLiant server. It sits in a 3.5-inch bay and connects through a SATA 6Gbps interface, giving the system reliable throughput for large backups, daily file storage, or archival data sets. A spindle speed of 7200 RPM keeps transfers steady and helps applications stay responsive.

Each drive arrives mounted in an HPE SmartDrive carrier that supports hot-plug installation. You can slide the carrier into a compatible Gen8, Gen9, or Gen10 ProLiant chassis without taking the server offline, then watch the front-panel LEDs confirm activity and status. This approach saves maintenance windows and keeps users productive.

The disk uses a 512e sector format, which emulates traditional 512-byte sectors on top of native 4K physical sectors. That layout aligns well with modern operating systems and makes better use of storage space. Support for Native Command Queuing allows the controller to reorder read and write requests intelligently, while an average seek time of about 8 milliseconds keeps latency in check during random workloads.

With its generous capacity, the 857648-B21 can extend a file server that hosts shared projects, give a backup target enough room for multiple retention points, or store large media libraries in a streaming or surveillance environment. Replacing an aging drive is straightforward thanks to the familiar SmartDrive design, and a single 10TB bay can deliver the headroom your infrastructure needs without added cabling or power requirements.

Highlights:

• 10TB capacity provides ample room for files, backups, and media libraries
