WD Datacenter HDD Technology

Datacenters are building out at an incredible rate to keep up with the tremendous growth of data. A 42U storage rack may include over 900 drives, providing almost 3 PB of storage. A system that contains many drives needs to be specially designed with features and technologies that ensure reliability, scalability, high availability and deliver consistent levels of performance. However, some of these features and technologies create challenges for hard drives – environmental, compatibility and workload challenges.

Here is a deeper look at these challenges and a explanation of how hard drives need to be designed for enterprise-class datacenter and cloud storage environments. Needless to say, datacenters present challenging environments for hard disk drives, and therefore require a fundamentally different class of drive – an enterprise-class drive.

Challenge #1: Environment

The datacenter environment employs specialized server and storage systems containing high-speed fans, densely-packed drives and temperature fluctuations.

IT Concerns:

  • High-speed fans are necessary to manage thermals but generate a wide range of vibrations
  • Densely-packed drives induce vibration on each other, potentially causing system-level performance degradation
  • Redundant power supplies reflect the multiple fail-over technologies that ensure 24/7 operation
  • Datacenter geographical location and cooling solutions vary, creating temperature and altitude extremes

WD's solution: A storage portfolio built to withstand harsh datacenter conditions.

  • RAFF + tied shaft motors are designed to compensate for multi-drive enclosures while ensuring consistent levels of performance
  • Higher quality components - designed for 24/7/365 operation (8,760 power-on hours per year)
  • High reliability with class-leading 5-year enterprise-grade warranty
  • Support for a wide range of temperature and altitude ratings


Challenge #2 Compatibility

Datacenters require different host bus adapters and fault-tolerance schemes like RAID and replication to ensure maximum performance, manageability and availability of a large amount of storage space.

IT Concerns:

  • RAID-based arrays demand high performance, tight performance variation, high error tolerance, and multiple interface options
  • Replication-based systems deliver high levels of data availability vs. traditional RAID and can tolerate lower reliability and lower performing devices
  • IT managers require interoperability across a wide range of host bus adapters that are deployed within their datacenters

WD's solution: Storage devices that work flawlessly with hundreds of different controllers in both RAID and replication arrays.

  • Higher error tolerances, tight performance variation, and SAS and SATA options for RAID systems
  • Datacenter quality products with right-sized error rates and performance that are optimized for replicated systems
  • Broad HBA compatibility including functional and signal-integrity testing also tuned and optimized for system interoperability

RAID-based array and Replication array

Challenge #3 Workload

Datacenter and cloud storage systems use a wide variety of operating systems and applications that need to work flawlessly with their chosen device. Workloads are typically ten times greater than the workload of desktop or notebook computers and the storage devices must be able to handle workload-intensive applications 24 hours a day, 365 days a year.

IT Concerns:

  • Applications have varying workloads – heavy reads or writes, sequential or random performance, low latency
  • Some datacenter applications require 100% workload, 24 hours per day, 365 days per year
  • OEMs are typically not aware of the types of workloads being employed on systems they sell

WD's solution: Storage devices that work flawlessly with hundreds of different controllers in both RAID and replication arrays.

  • Higher RPM models for performance demanding applications
  • Products are designed for 8,760 power-on hours per year, reading and writing continuously

About Western Digital Advanced Format Hard Drives

WD Advanced Format drives are specifically optimized for Mac and the latest Windows operating systems such as Windows Vista and Windows 7 with a clean install. Advanced Format Technology is being adopted by WD and other drive manufacturers to increase media format efficiency, thus enabling larger drive capacities.

Using your WD Advanced Format Hard Drive with a Windows Operating System may require you to run the WD Align Windows software utility after you install your operating system or partition and format the drive as a secondary drive. The WD Align software aligns existing partitions on the Advanced Format drive to ensure it provides full performance for certain configurations. (Please see table for configuration details)

If your operating system is either Windows 7 or Vista, WD recommends using the latest Intel driver version 9.6 or later for maximum performance in all situations. Please visit Intel for the latest driver downloads.

What does Advanced Formatting mean to me?

Advanced formatting optimizes hard drives to take advantage of the capabilities of newer operating systems. This capability enables hard disk drive manufacturers the ability to design larger capacity hard drives, now and into the future.

What are the benefits of Advanced Formatting?

Advanced Formatting enables hard drive companies to read and write more data into the same available space on the hard drive.

Can I install an Advanced Format hard drive in my system?

New drives from WD are optimized for operation with Windows 7, Windows Vista and Mac OS X Tiger, Leopard, Snow Leopard. If you are attempting a clean install of an Advanced Format hard drive into a system running one of the Operating Systems listed above the installation process follows standard procedure. For older operating systems such as Windows XP, and for users using cloning software, users must run the WD Align utility to achieve the full performance of the drive. (See table for configuration details)

Early 3.5-inch WD drives with Advanced Format supported jumper pins 7 – 8. Placing a jumper on these pins adjusted the drive's internal alignment for single partition XP installations. Support for this jumper setting is no longer needed on newer drives. For optimal performance on all XP installations WD recommends running the WD Align utility.

If you have a drive that supports jumper pins 7 – 8 and have a jumper in place on those pins, the following is additional information to assist you if you are re-installing an Operating System or re-partitioning the drive:

  • IMPORTANT: You must backup your drive before making any changes, including removal of the jumper.
  • Re-partition the drive: Turn off power to the drive and remove the jumper from pins 7 – 8. Power-on and re-partition the drive (NOTE: All previous data on the drive will be lost).
  • Preserve Current Partition: If you are installing an Operating System over the existing partition, keep the jumper on pins 7 – 8. The drive is already aligned to the existing partition so you do not need to remove the jumper.
  • If you change the setting of jumper 7 – 8, you will lose all previous data and the drive must be re-partitioned.

For a clean install of Windows XP using multiple partitions, DO NOT install the jumper; simply run the WD Align utility.

Can I install a WD Advanced Format Drive under non-Windows Operating Systems, such as MacOS and Linux?

WD Advanced Format Drives can be used under non-Windows Operating Systems.

Do I need a special driver to install a WD Advanced Format Drive on an Intel chipset?

If your operating system is either Windows 7 or Vista, we recommend the following for maximum performance in all situations:

  • For Intel chipset, use the latest Intel driver version 9.6 or later. Please visit Intel for the latest driver downloads at http://www.intel.com/support/chipsets/imsm/sb/CS-031502.htm
  • For AMD chipset, no driver update is required.
  • For Nvidia chipset, please visit http://support.microsoft.com/kb/982018 for additional information.

What is WD Align utility software?

The WD Align utility enables older operating systems to operate at full performance on Advanced Format hard drives.

How long will running the WD Align utility take?

It will vary based on your operating system and how much data is on the disk, but the WD Align utility should take about 20 minutes to complete on freshly installed drive images with no data files. We recommend disabling Power Management prior to starting the partitioning alignment process.

Does the WD Align utility have to be run again if a drive is reformatted?

No, users will only need to run WD Align one time after initially installing Windows XP. Once Windows XP has been aligned, it will stay aligned even if the drive is reformatted or many files are added or removed.

What models utilize Advanced Format technology?

Some models of the WD Green and WD Blue product families are built using Advanced Format technology. Over time more models and capacities will be added. WD drives with Advanced Format technology include special installation information on the drive label so be sure to read the label on your drive before installing it.

Does WD Align work with Western Digital USB and Firewire drives, such as My Book and My Passport drives?

If you do not change the partitions on a Western Digital USB or Firewire drive, the drive is already optimally aligned. However, all Western Digital USB and Firewire drives are specifically designed to work with WD Align. If you repartition a Western Digital USB or Firewire drive, WD Align should be run to optimally align the partition or partitions.

Can I install my Advanced Format Drive into a USB enclosure?
