SKU CH-HRPQ-EB9YW

A 3 TB 3.5" 7200 rpm SAS internal hard drive with 512e format and hot-swap support for compatible servers

  • 3 TB capacity stores large datasets
  • 7200 rpm spindle speed delivers responsive data access
  • 6Gb/s SAS interface provides reliable server connectivity
  • Hot-swap 3.5" form factor enables drive replacement without downtime
  • RoHS certified design meets environmental standards

3 TB Near-Line SAS drive for server arrays

This Lenovo 3.5-inch internal hard drive provides 3 TB of storage on a 6Gb/s SAS interface. It spins at 7200 rpm and uses a 512e disk format. The unit is built for hot-swap bays in compatible System x servers.

Sustained throughput on near-line workloads

The 7200 rpm spindle speed delivers steady sequential bandwidth for bulk data ingest, backup targets and archival duties. Near-line SAS firmware prioritises consistent latency over burst peaks during extended write sessions. The 6Gb/s link keeps the pipe full without saturating the controller.

Thermals and power in a 1-inch bay

The 1-inch high form factor fits standard 3.5-inch hot-swap cages with 5.8-inch depth. RoHS-compliant construction and a 1.52 lb weight indicate conventional motor and actuator power draw. Active cooling in the server chassis maintains safe operating temperatures under continuous operation.

Questions about this item

How loud does the 7200 rpm SAS drive run when it spins continuously in a server?

The 7200 rpm spindle and 6Gb/s SAS interface are built for near-line workloads, so the drive runs at typical enterprise acoustics for a 3.5" 1.52 lb mechanism.

What host connector and controller does the 6Gb/s SAS drive require to operate?

A backplane or HBA with a 6Gb/s SAS port is needed; the 3.5" drive uses the standard SAS connector and 512e format.

Will the 90Y8577 work in a System x3550 M4 alongside existing SAS drives?

Yes, the drive is listed for System x3550 M4 and other System x servers, and its hot-swap tray fits the same 3.5" SAS bays.
