DELL ST91000640SS 1.2TB 2.5 7200RPM SAS internal hard drive

SKU CH-K3PY-J1X50 MPN ST91000640SS

1.2 TB SAS internal hard drive with 7200 RPM, 64 MB cache and hot-swap tray

  • 2 TB storage capacity for demanding workloads
  • 7200 RPM spindle speed delivers fast data access
  • SAS interface provides reliable enterprise connectivity
  • 64 MB cache boosts read and write performance
  • Hot-swap tray enables drive replacement without downtime

Capacity and interface

This 1.2 TB SAS 2 drive fits a 2.5 inch bay and spins at 7200 RPM. It is aimed at server or storage-array operators who need hot-swap capability and a 64 MB cache for mixed read and write workloads.

Sustained workload behaviour

The 7200 RPM spindle and SAS 2 link deliver steady throughput for sequential and random I/O during extended operations. Hot-swap support allows replacement without powering down the enclosure, reducing downtime in multi-drive deployments.

Pre-order checks

Verify that your controller or backplane supports SAS 2 and provides a 2.5 inch hot-swap tray. Confirm the system can address the full 1.2 TB capacity and that the SAS connector matches the drive's pin-out.

Küsimused selle toote kohta

How much heat and noise does the 7200RPM SAS drive produce during continuous use?

The 7200RPM spindle and 64MB cache generate typical enterprise-level heat and acoustic output for a 2.5-inch SAS drive; ensure your chassis provides adequate airflow for sustained operation.

What controller or backplane is required to run this SAS 2 drive?

A SAS 2 (6Gbps) host bus adapter, RAID controller, or server backplane with a 2.5-inch SFF bay is needed; the included tray fits Dell PowerEdge sleds.

Will this 1.2TB SAS drive work in an older server that only supports SAS 1 (3Gbps)?

Yes, the SAS 2 interface negotiates down to 3Gbps on legacy controllers, delivering full 1.2TB capacity at the slower link speed.
