Enterprise capacity drive

The Dell Ultrastar DC HC520 delivers 12TB of storage in a 3.5-inch form factor. It spins at 7200 RPM with a 256MB cache and uses a SAS 12Gb/s interface. The drive employs 512e sector formatting and HelioSeal technology for efficient 24x7 operation in enterprise environments.

Suited for high-density arrays

This drive fits enterprise servers, storage arrays and backup systems that require large-capacity SAS drives for continuous workloads. It is not suitable for laptops or small-form-factor devices that cannot accommodate a 3.5-inch drive. Systems without a SAS 12Gb/s host interface or 512e sector support should consider other options.

SAS 12Gb/s interface

The SAS 12Gb/s connection determines compatibility with host controllers and backplanes. Verify that the target system supports this interface speed and 512e sector format before deployment. This single specification governs whether the drive can be installed and used at its rated performance.

Perguntas sobre este artigo

Will the 3.5in form factor fit my laptop drive bay?

This is a 3.5in enterprise drive, so it requires a 3.5in bay or caddy; most laptops only accept 2.5in drives, making internal fit unlikely.

How do I connect the SAS 12Gb/s interface, and what step is often missed?

Attach the drive to a SAS 12Gb/s backplane or HBA with a compatible SAS cable; the step often missed is ensuring the controller supports 512e sector format for proper recognition.

When will the HelioSeal helium fill need replacement?

The HelioSeal enclosure is factory sealed for the drive's service life; no helium refill or seal maintenance is required by the user.
