SKU CH-7XQY-KB3Y4

A 1 TB 7.2K SAS drive in 2.5" form factor with 64 MB cache, supplied in a lot of 10 with caddies

  • 1 TB capacity for bulk data storage
  • 7200 RPM spindle speed for responsive access
  • 64 MB cache to accelerate read and write operations
  • SAS 6 Gb/s interface for reliable server connectivity
  • Includes R Series caddy for direct 2.5 inch bay installation

Dell Constellation.2 1TB SAS drive

This Dell Constellation.2 drive delivers 1000GB of storage in a 2.5 inch form factor. It spins at 7200RPM and connects through a 6Gb/s SAS interface with a 64MB cache. The unit includes an R Series caddy for installation in compatible bays. Condition is new.

Suits servers and arrays needing 2.5 inch SAS drives

This drive fits systems that accept 2.5 inch SAS hard drives running at 7200RPM with 6Gb/s throughput. Buyers needing a different physical size, a different interface protocol, or higher capacity per spindle should look elsewhere. The included tray matches Dell R Series mounting points.

Interface is 6Gb/s SAS

The single specification that decides fitment is the 6Gb/s SAS interface on a 2.5 inch frame. Controllers and backplanes must support SAS at this speed and the small form factor. Without that match the drive will not function in the target system.

  • 7200 RPM spindle speed for responsive access
  • 64 MB cache to accelerate read and write operations
  • SAS 6 Gb/s interface for reliable server connectivity

Questions about this item

Will the 2.5" SAS 6Gb/s interface work with my existing SAS 3Gb/s backplane?

The drive uses a 2.5" SAS 6Gb/s interface which is backward compatible with 3Gb/s backplanes, though it will operate at the lower 3Gb/s speed when connected to older controllers.

How can I verify the 7200RPM drive is performing correctly after installation?

Check SMART data for the ST91000640SS model showing 7200RPM spindle speed, confirm the 64MB cache is detected, and run a surface scan to verify the 1000GB capacity reads without errors.

Does the lot include ten R Series caddies or trays for mounting in a server chassis?

The lot of 10 drives includes R Series caddies for each 2.5" SAS drive, so no separate mounting hardware is required for compatible Dell server bays.
