WD Ultrastar 4TB Enterprise Hard Drive
Economics and Access Speed: Key Requirements for Low Capacity HDDs in the Data Center
As the industry evolves to develop purpose-built solutions for growing data storage requirements, IT managers continue to rely on lower capacity drives that are economical to acquire, yet deliver quick and reliable data access for traditional data center applications. Ultrastar® DC HC310* is a low-capacity HDD, that helps address economic and access requirements of many traditional IT workloads. Low capacity drives also help address architecture limitations. Part of our mid-capacity DC HC300 series, the Ultrastar DC HC310 is designed for traditional storage and server applications as well as distributed and scalable computing, including block and fi le storage architectures, providing fast 7,200 RPM performance and lower acquisition cost to help ease budget constraints. Ultrastar DC HC310 is offered with either 6Gb/s SATA or 12Gb/s SAS interface in a choice of 512e or 4Kn formats.
Technology Innovation Delivers Effi ciency and Performance for Traditional and Legacy Systems
Ultrastar DC HC310 is based on a new 4-disk air platform design that uses conventional magnetic recording (CMR) technology in a 3.5-inch large form factor. Compared to the prior generation, Ultrastar 7K6000, the DC HC310 delivers a 12% performance boost and uses slightly larger-diameter media. It features a second-generation, dual-stage micro actuator to enhance head positioning accuracy for better drive performance. Write performance gains are also supported by Western Digital's media cache architecture, a disk-based caching technology that provides a large cache area on the disk, which also improves reliability and data integrity during unexpected power loss. Finally, the addition of fl ash-based non-volatile cache (NVC) on both SATA and SAS models helps improve write performance. The Ultrastar DC HC310 also includes a Rebuild Assist feature, which helps dramatically reduce RAID rebuild times and maintain system performance during the rebuild process.

Data Security with Trusted Quality, Reliability
Compliance and privacy requirements drive the need for increased data security. Ultrastar DC HC310 helps protect data from unauthorized use by offering security and encryption options. SAS models offer hardware-based encryption options, including a Trusted Computing Group (TCG) Enterprise_A, TCG with FIPS 140-2 certifi cation, Level 2. The Ultrastar DC HC310 extends Western Digital's long-standing tradition of
reliability leadership with a 2M-hour MTBF² rating and a 5-year limited warranty.

As an international traveller you are entitled to bring a certain amount/value of goods that are free of Customs duty and exempt Goods and Services tax (GST) into New Zealand. This is called your duty free allowance and personal goods concession. It is important to review these for any purchases you make on The Mall.
Your duty free allowance entitles you to bring into New Zealand the following quantities of alcohol products free of customs duty and GST provided you are over 17 years of age. You do need to be 18 years or over to purchase.
- Up to six bottles (4.5 litres) of wine, champagne, port or sherry or
- Up to twelve cans (4.5 litres) of beer
- And three bottles (or other containers) each containing not more than 1125ml of spirits, liqueur, or other spirituous beverages
Goods other than alcohol and tobacco, whether purchased overseas or purchased duty free in New Zealand, that have a combined total value not exceeding NZ$700 may also be brought as part of your personal goods concession.
When travelling overseas there are legal limits on the amount of duty free alcohol and other goods you can take with you. These amounts will vary depending on the country you are flying into. We always recommend you check the latest limits and exemptions.
Your order can be picked up at an Auckland Airport Collection Point. There is one in departures and one at arrivals in the international terminal. See map
You will need to bring your order confirmation email and show your passport to collect your order.
If you’re departing Auckland Airport, we recommend that you come to the Auckland Airport Collection Point at least 60 minutes before your flight. If you miss your pickup time or your flight details have changed please let us know as soon as possible.
