The Difference Among Blue Disk, Black Disk and Green Disk of WD

Black Disk

High performance, large cache, fast speed

Suitable for: enterprises, large throughput server

Code: LS WD Caviar Black desktop

HDD 2 TB, SATA 3 Gb/s, 64MB cache, 7200 RPM. It is suitable for the ultra-high performance of high-end computing. It is equipped the most sophisticated high-capacity HDD for personal computers. WD Caviar Black HDD has high performance electronic architecture and rock solid mechanical structure. It provides perfect storage solution for your fully equipped PC or high-performance game computer. Low heat HDD running, non-contact head technology and highly sophisticated vibration protection, it ensures higher reliability and more durable data processing capability.

Main features: High performance electronics architecture.

Dualprocessor – double processing capacity, maximize performance, Large and faster 64 MB cache means better performance, Rock solid mechanical structure.

Dual Drive System – Dual-drive head positioning system, which could significantly improve the positioning accuracy of data tracking. Main driver uses conventional electromagnetic actuator principles which provides coarse-grained displacement. Spare driver uses pressure electric technology that optimizes head positioning so that it achieves a higher level of accuracy. (limited 2 TB)

StableTrac – Both ends of the spindle motor is fixed to the hard disk, in order to reduce fibrillation of system operation and stabilize platters. You could seek track accurately when read and write HDD.

NoTouch ramp load technology – The recording head never touches the disk media, in order to minimize the wear of the recording head and media and provide better protection in transportation.

Large capacity – the capacity of WD Caviar Black SATA HDD has been reached 2 TB.

How does these WD HDDs protect your data?

Data Lifeguard is a senior data protecting functions. It includes anti-vibration, environmental protection system, real-time embedded error protection and repair function.

Data Lifeguard technology of WD could automatically find, isolate and repair problems which may caused by HDD overused. Data Lifeguard Tools is software tools specially designed for WD HDDs. It could cooperate with embedded Data Liftguard tools and make HDD installment, diagnosis and repair much more easier. Short Guard real-time protection make HDD against damage from the instant bumps and vibrations when it is running. This technology enables WD Caviar drives to achieve industry-leading shock specifications.

 

Blue Disk

Household, Cost-effective, Overall more balanced, Longest life

Suitable for: storing data and general use

Code: KS WD Caviar Blue SATA

HDD 1TB, SATA 3 Gb/s, cache 32MB, 7200 RPM. It is suitable for performance and reliability for everyday computing applications. Relying on SATA and PATA interface and 32MB cache, this series HDDs have overall stronger performances. In order to facilitate customer to choose HDDs, all common WD Caviar SE16, WD Caviar SE and WD Caviar are made into one category, which are called WD Caviar Blue. Those HDDs are built by the quality standard of acclaimed Western Digital and they have many features related to performance.

Main features: PATA interface – Enhanced Integrated Drive Electronics(EIDE) HDD. It is also called parallel ATA (PATA) HDD, which has been become the standard of computer industry for 10 years.

SATA – Serial ATA(SATA)HDD has become the new standard rapidly. Motherboard manufacturers install SATA interface in their board card. Compared with PATA HDDs, SATA HDDs’ cable is narrower so that using SATA HDD can increase air flow and reduce the confusion of computer case.

Performance difference – The highest data transfer rate of PATA HDDs support 100MB/s and all WD Caviar Blue SATA HDDs support 3 Gb/s transmission rate.

Reliable performance – Relying on SATA and PATA interfaces and 32 MB cache. This series HDDs have overall stronger performance.

Capacity – WD Caviar Blue HDD capacity is up to 1 TB. It could fulfill your storage needs.

Low heat – Maintaining low heat of HDD could improve its reliability.

Quiet operation – Whisper Drive technology could lower the noise into the level of human hearing threshold. SoftSeek technology simplifies reading and writing seeking algorithms and improves operating efficiency.

NoTouch ramp load technology – The recording head never touch the disk media, in order to minimize the wear of the recording head and media and provide better protection in transportation.

IntelliSeek technology – Calculating optimum speeds to lower power consumption, noise and vibration. (Provide 120 GB and higher capacity)

Green Disk

Environmental protection, silent, low heat, save power, common performance, automatically adjust speed between 5400 to 7200

Suitble for: As a download disk

Code: CS

With the increase of hard drive capacity, the energy demand of HDD also increased. WD Caviar Green HDD builds higher capacity and stable performance coordinated system for customers who pay attention to environmental protection.

Main features: Reducing power consumption – WD use its IntelliSeek, NoTouch and IntelliPower technologies reduce power consumption, lower maximum of 40% power consumption than the standard desktop drives.

Auxiliary equipments make environmental protection PC become possible. Compared to desktop products, power consumption of every WD Caviar green HDD can save 4 to 5 watts. When customers who pay attention to save energy build large capacity system, it could earn the balance of system performance, reliability and energy saving features.

Low heat, silent – WD Green Power technology can make operation temperature lower, so the reliability is higher and noise is lower. It is suitable for varies PC and external HDD.

Large capacity – The highest capacity is 2 TB. It provides most available capacity for operation system of various storage-intensive programs and Window Vista grade consumption space. The rest space can be used to store photos, music and videos.

Best choice for external HDD – External HDD manufacturers needn’t install cooling devices when use its large capacity products. WD Caviar Green HDDs have lowest heat and minimum noise.

IntelliPower technology – Speed, data transfer rate and the precise balance of caching algorithm. It aims to achieve significant energy saving and solid performance.

IntelliSeek technology – Calculate the best data search speed, reduce power waste, noise and vibration.

NoTouch ramp load technology – Recording head never touches the disk media, in order to minimize the wear of the recording head and media and provide better protection in transportation.

StableTrac – Both ends of the spindle motor is fixed to the hard disk, in order to reduce fibrillation of system operation and stabilize platters. You could seek track accurately when read and write HDD.

Running low power consumption – WD Caviar Green HDDs have lower power consumption and the lower in peak load.

Advanced power technology – Electronic components have lowest power consumption compared to congeneric product. It suitable for environment friendly PC and external storage devices which need lower power consumption, lower heat to run and less operating noise.
