Western Digital Ultrastar DC HC550 18TB 3.5 inch SATA review and prices in Kenya

Western Digital Ultrastar® DC HC550

Highlights:

• 18TB of storage in a 3.5-inch form factor
• CMR technology
• Triple stage actuator
• HelioSeal® for outstanding energy efficiency
• 2.5 million hours MTBF (estimate)

Total cost of ownership (TCO) as a crucial factor for data center architecture

Decisions when equipping data centers are based on costs. And higher capacity hard drives play an important role in reducing costs. An 18TB hard drive offers 29% more storage capacity than a 14TB version in the same form factor. Higher-capacity hard drives enable lower data center capital expenditures because less hardware is required and system costs are lower than using lower-capacity drives. Low-power, high-reliability helium-filled hard drives reduce energy and maintenance costs, helping to reduce operating expenses. For example, if drives with 18 TB storage capacity are used instead of 14 TB hard drives, 22% fewer racks are required and idle power consumption is 21% lower per TB. This results in significant savings in data center total cost of ownership.

More capacity with new technology

The Ultrastar DC HC550 establishes a new generation of hard drives with innovative technologies and nine magnetic disks. It offers 18 TB of storage capacity and combines technologies for higher data density with increased performance and reduced energy consumption.

• The first hard drive on the market with Energy-Assisted Magnetic Recording (EAMR) increases write performance and thus data density.
• The first use of Triple State Actuator (TSA) technology enables precise head positioning. This improves performance and increases data density.
• HelioSeal® technology is the basis for Western Digital’s high-capacity hard drives. The Ultrastar DC HC550 is the sixth generation of HelioSeal products. Western Digital has sold more than 65 million HelioSeal products to date.

Proven reliability and quality when processing large amounts of data

With very high capacity and reliability of an estimated 2.5 million hours MTBF, the Ultrastar DC HC550 is ideal for object storage applications. Object storage systems with erasure coding provide better data durability compared to RAID systems because of their tolerance to simultaneous error conditions.

The DC HC550 has security and encryption features that protect data from unauthorized access and is available in SED versions with SATA and SAS. In addition, an SED model with FIPS certification and SAS interface will come onto the market.

The Ultrastar DC HC550 hard drive from Western Digital offers very high storage capacity, reduces operating costs and enables greater added value in your data center.
