Hard drives are a critical component of any modern business. Since the vast majority of information is now stored digitally, from customer records to surveillance feeds, financial information to company intellectual property, having the right hard drive to store your data is vital for the smooth and profitable operations of any organisation.

However, given the sheer volume of different hard drive products out there, choosing the right one for the right job can be a daunting task, says Kalvin Subbadu, Components Sales Manager at WD South Africa.

This handy guide highlights five of WD's internal hard drives in its Components division for businesses and professionals, giving you an overview of the key features and functionality they provide, as well as the different scenarios and environments they have been designed to function optimally within.

1. WD Red - designed for small and home office NAS systems

The WD Red drives have been designed specifically for network attached storage (NAS) systems with one to five bays. They have been compatibility tested in demanding 24x7 environments and are suited to the needs of a small or home office NAS. In addition, these hard drives feature exclusive NASware technology for seamless integration, robust data protection and optimal performance necessary in a NAS or RAID environment.

Red drives are also highly energy efficient, with reduced power consumption and lower operating temperatures. 3D Active Balance Plus offers enhanced dual-plane balance control to minimise vibration and noise. These features result in a more reliable and more affordable solution for always-on NAS environments. WD Red hard drives feature a three-year limited warranty and free access to a dedicated 24-hour international support line exclusively for WD Red customers.

2. WD Black - maximum performance for power computing

WD Black drives offer more speed, more power and more performance. This makes them ideal for high-performance applications such as photo and video editing, gaming and power PCs. They are designed for any user looking for leading-edge performance from their desktop or notebook PC.

High performance, high capacity, high reliability and cutting-edge technology are what set WD Black apart. Performance enhancing features deliver the speed needed for demanding applications, a dual processor delivers twice the processing power, a dynamic cache improves performance in real-time, and a rock-solid mechanical architecture with enhanced reliability features helps to protect the drive and the data stored on it.

NoTouch Ramp Load technology means the recording head never touches the disk media, resulting in significantly less wear to the recording head and better drive protection in transit. The drives have also been tested for compatibility on multiple platforms and systems, and feature an industry-leading five-year limited warranty.

3. WD AV-GP - engineered for 24x7 performance in video environments

WD AV-GP drives deliver a 24x7 quiet operation, low temperatures, high reliability and optimised streaming, with capacities of up to 3TB. These drives have been designed to operate in intense, always-on audio-video (AV) applications and are ideal for use in digital video recorders (DVRs), personal video recorders (PVRs), set-top boxes and video surveillance recording.

These drives are highly energy efficient (the GP stands for Green Power), cool and quiet, and offer greater reliability as a result. IntelliSeek calculates optimal seek speeds to lower power consumption, noise and vibration, while IntelliPark automatically unloads the heads during idle time, reducing aerodynamic drag and lowering power consumption. Pre-emptive Wear Levelling (PWR) reduces uneven wear on the drive surface to extend the life of the drive, and SilkStream technology is optimised for smooth, continuous digital video playback of up to 12 simultaneous HD streams.

AV-GP drives have been tested for compatibility in a broad range of AV products, and offer best-in-class reliability with an incredible one million hours mean time between failure (MTBF) and a three-year limited warranty.

4. WD Re - durable storage for high-availability deployments

WD Re drives are the industry's highest capacity nearline drive, offering up to 4TB to suit even the most demanding storage needs. They deliver best-in-class performance, low power consumption, enterprise-ready storage with high capacity, high performance and 24x7 reliability. These drives are ideal for demanding, high-performance computing and business-critical environments.

The Re drives are packed with WD's best technology: Dual processors, RAFF, dual actuator, StableTrac, a multi-axis shock sensor, RAID-specific TLER, burn-in testing, dynamic fly height and NoTouch ramp load. These drives have been field-tested to an incredible 1.2 million hour MTBF, delivering high performance with the highest levels of reliability. Re drives have incredible power, supreme operational capacity and maximum reliability, and are ideally suited to always-on critical applications. They feature a 5-year limited warranty.

5. WD Se - storage for NAS and scale-out architectures

WD Se drives offer cost-effective, reliable data centre capacity hard drives, ideal for scale-out architectures. They deliver the perfect combination of performance, reliability and workload capability, with the hardiness of true enterprise-class design. These drives are best suited to bulk cloud storage, replicated environments, content delivery networks, large-scale NAS environments, backup and archiving.

The features in the Se range have been designed to optimise the drives for data centre environments. RAID-specific time-limited error recovery (TLER) prevents drive fallout caused by the extended hard drive error recovery process common on most desktop drives, while StableTrac technology secures the motor shaft at both ends to reduce system-induced vibration and stabilise the platters for accurate tracking.

A multi-axis shock sensor automatically detects the most subtle of shock events and compensates to protect the data, and enhanced Rotary Acceleration Feed Forward (RAFF) monitors the drive and corrects vibration in real-time for significant performance enhancements. Dual processors, dynamic fly-height technology and dual actuator technology all act to further improve performance, and each drive is subjected to extended burn-in testing to ensure reliable operation. The Se drives feature a five-year limited warranty.

A drive for every situation

The complete range of WD drives offers business and enterprise users the best technology to keep their data safe, protected and available. From servers to video streaming, large enterprise to small office, WD has the right hard drive for the job to deliver maximum performance, optimal reliability, and a sound return on investment.
