Silver 2.5 inch SAS hard drive with green circuit board visible

DELL

DELL Constellation.2 1TB 7.2K 2.5" 6G SAS internal hard drive

SKU CH-NZPY-33AGX MPN Constellation.2

A 1 TB, 7.2 K RPM SAS hard drive in a 2.5" form factor with 64 MB cache and hot-swap support

  • 1 TB capacity for bulk storage
  • 2 K RPM spindle speed for steady throughput
  • 6 Gb/s SAS interface for server connectivity
  • 64 MB cache to smooth burst workloads
  • 5-inch hot-swap form factor fits dense bays

1 TB 6 Gb/s SAS hard drive

This 1 TB 2.5-inch drive uses a 6 Gb/s SAS interface and spins at 7.2 K RPM with a 64 MB cache. It is built for servers and storage arrays that need hot-swap capability and consistent throughput.

Upgrade from smaller SAS or nearline SATA drives

Replacing a lower-capacity SAS drive with this 1 TB model adds space without changing cabling or backplane infrastructure. The jump is worth it when current bays are full and the workload tolerates 7.2 K RPM latency.

Check SAS backplane and controller compatibility

Verify that your system accepts 2.5-inch SAS drives and that the controller supports 6 Gb/s speeds. Confirm the hot-swap tray matches the drive form factor before ordering.

Preguntas sobre este artículo

What drive bay size does the 2.5" Constellation.2 require?

The drive fits a standard 2.5-inch internal bay and uses a 6G SAS connector for data and power.

Which step is often missed when installing the ST91000640SS in a hot-swap tray?

The SAS connector must be fully seated until the tray latch clicks; a partial insert leaves the drive invisible to the controller.

When should the 64MB cache drive be replaced in a 7.2K SAS array?

Replace it once SMART reallocated-sector count rises or after the rated workload limit for 7.2K SAS drives is reached.
