Dell 73 GB 15K SAS Drive

This is a new Dell internal hard drive with a 73 GB capacity, 15K rotational speed and a SAS interface. The 2.5 inch form factor suits enterprise servers and storage arrays that require high-performance 512n sector drives.

Suits SAS 6 Gbps systems needing 73 GB 15K storage

It fits administrators who need a 512n native sector drive for compatibility with legacy RAID controllers or operating systems. It is not for systems that lack a SAS backplane or controller, nor for workloads that demand higher capacities.

512n native sector format

The drive uses a 512-byte native sector size rather than an advanced format. This specification determines whether the drive will work with older controllers and operating systems that do not support 4K sector emulation.

Highlights

  • 15K RPM speeds enterprise workloads
  • 73 GB capacity fits critical datasets
  • 512n sectors ensure legacy compatibility
  • 6 Gbps SAS interface maximises throughput
  • 5 inch form factor saves space

Questions about this item

Does the 6 Gbps SAS interface limit the drive's real-world throughput?

The 6 Gbps SAS link sets the interface ceiling, so sustained transfers cannot exceed what that bus allows.

What physical space and mounting does the 2.5-inch form factor require?

It fits a standard 2.5-inch drive bay and uses the SAS connector layout common to that size.

How is the drive installed, and what step is often missed?

Slide it into the bay, secure it with the correct screws, and attach both the SAS data and power cables firmly.
