Western Digital 5000 GB Red 64 megabytes cache

Hard disk WD Red is the world's first model, which was developed exclusively for NAS systems . The actual unit is tested to be useable in continuous operation (24x7) in the home or small business NAS with one to five positions (for larger systems NAS is better to use enterprise disks - enterprise). The basis is to 35% increase in MTBF statistical indicators (Mean time between failures), which indicates the mean time in hours, after which it is expected that the device will work flawlessly. WD Red is simply more resilient and robust solution than what the standard desktop hard drives, yet is not significantly more expensive - precisely because it unhesitatingly recommend for your NAS!

NASware 2.0 - the secret is in the technology

The advanced firmware provides for seamless integration, robust data protection and optimal performance in RAID and NAS environments. Unique algorithms in NASware performance tuning , optimizes the consumption of electrical energy and saves you money. Lower power consumption also reduces the heating disk, which leads to further increased reliability and durability. Intelligent error correction system prevents the drives from the RAID discarded due to too long recovery from errors. When unexpected power outages extra NASware ensure completion of the order prior to shutting down the drive.

As will be appreciated, not only by system integrators?

• Support for streaming - NASware boasts compatibility with the package ATA Streaming Feature Set, which is important for use in audiovisual repositories, such as Windows Media Center.
• SMART Command Transport (SCT) - NASware allows you to monitor and measure the performance of the disk through SMART command set. SMART can display data such as temperature profiles, statistics, disk access and more ... NASware also offers temperature measurement with a maximum deviation of ± 1 ° C.
• Power Management - Allows you to optimize the energy consumption within the NAS.
• BIC Performance - Optimized Search BIC provides performance at lower power consumption and noise.

3D Active Balance Plus

Improved technology double ensure a balance significantly improves overall performance and reliability of disk. Hard drives that are not properly balanced, can in systems with multiple disks cause excessive vibration and noise, reduce disc life and reduce performance over time.

Why not choose a range of WD Red?

• Specific needs NAS - Desktop hard drives are designed for use in desktop PCs and when used in RAID and NAS systems, offer nearly optimal performance or protection for your sensitive data.
• Compatibility - For hard drives for desktop computer can be a problem of integration into the NAS system.
• Reliability - Desktop hard drives are not capable of long-term work at high temperatures or in continuous operation.
• The error recovery - Desktop hard drives are not intended for use in RAID environments and include drivers that prevent the RAID driver to intervene when errors leading to failure of the RAID array. Follow RAID array reconstruction costs users time and unnecessary effort.
• Noise and vibration - Desktop drives are optimized to minimize noise and vibration. In addition to reducing the user's comfort and their installation in NAS systems run the risk of reduced reliability and durability.

For proper functionality under Windows XP and older OS, we recommend WD Align utility.
