Over the last few years there has been a massive influx of information and data quantity which created what the industry views as a "new necessity." This new necessity requires businesses to collect, have access to, and store data on a long-term basis. While it isn’t an entirely new problem, the rapid data growth in recent years has the spotlight focused on long-term data management.
How is all this newly accumulated data being stored, how frequently is it being accessed, and for how long can content creators have confidence that their personal and business data can be retrieved reliably? These are just a few of the questions surrounding "Cold Storage".
So what exactly is cold storage? Put simply, it's an affordable way to reliably store important yet infrequently accessed data for long periods of time. According to IDC, "cold storage is method operation of a data storage device or system for inactive data where an explicit trade-off is made, resulting in data retrieval response times beyond what may be considered normally acceptable to online or production applications in order to achieve significant capital and operational savings." With consumer and business expectations changing, we must begin to examine this trade-off and determine who and what defines "acceptable performance" – a few seconds, minutes, more? This acceptable timeframe will vary from business to business, and even by application.
In order to address the new necessity to access cold data more efficiently and store ever increasing amounts of new data such as email, databases, and legal and accounting documents, etc., businesses must decide how they will store all this data. There are currently three primary options to handle storing all this data. Legacy Archiving (Tape), Virtual Tape Libraries (VTL), and Disk-based Archiving (HDD).
In order to address these new requirements to access archived data more efficiently and store ever increasing amounts of new data, such as email, databases, legal and accounting backups, etc., businesses must look at new storage alternatives built to meet these needs in a cost effective manner.
Reduced medial spin lowers power consumption and optimizes the drive’s read/write ratio for the rigid requirements of cold storage systems.
Proven cold storage reliability
With 700 PBs of cold storage deployed in datacenters already*, WD's 4th generation WD Ae utilizes innovative technology to reduce power consumption and lower operating temperature, which results in a more reliable and affordable solution for cold storage data archives.

Cost-effective capacity storage
Moving cold data to value-optimized archive media delivers significant TCO savings by freeing up expensive performance-critical storage system capacity.
As technology and manufacturing process mature over time the incremental capacity increases are realized. WD’s innovative Progressive Capacity model allows distribution of these incrementally higher capacity models taking advantage of their full capacity – 6.5TB for instance.
Quick Data Retrieval
Access time to cold data is quickly becoming a critical feature of an on-line archive system and end users can't wait hours, days, or weeks for this data to become available. The spin-down capability of WD Ae provides much faster access times than conventional archive tape with data access times of less than 20 seconds for on-demand data requests.
Cold-data power management
Best-in-class power management, reduced heat output, and next-generation technologies such as IntelliSeek combine to deliver a balance of performance and power that is perfect for cold data archive storage architectures.
3D Active Balance Plus
Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.
Dual actuator technology
A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
The WD Ae is best suited for cold storage, backup and data archiving where data is stored on disk but rarely if almost never read again yet may be critical at some future point, prime examples being legal data or photo backups.
NoTouch ramp load technology
The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
24x7 dedicated customer support
Every WD Ae hard drive comes with our world-class professional support services including a dedicated 24x7 support line (available in English, other regional support hours vary) and a 3-year limited warranty.
