Hard disk drives are today\'s fastest permanent storage media and have a large capacity. For this two reasons they are the most used storage medium in computers and servers. When buying a new hard disk, there are three important things to consider:\
\
- The connection of the disk to the computer or other device you will be using it with has a big influence on the speed with which data can be read from/written to the disk. Make sure the connection of the disk you buy is compatible with your computer!\
\
- The rotational speed is also important for the speed with which data can be read from/written to the disk and determines the time it takes to find a file on the disk.\
\
- Last but not least, the storage capacity of the disk, i.e. the amount of data that can be stored on the disk.

The official marketing text of Western Digital HDCaviarRE 120GB 120GB internal hard drive as supplied by the manufacturer
Western Digital's WD Caviar® RE 7200 RPM hard drives are engineered to thrive in a high duty cycle RAID system while still offering traditional low cost-per-capacity desktop value. Designed and manufactured to enterprise-class standards, WD Caviar RE drives provide RAID-specific time limited error recovery (TLER) to prevent drive fallout caused by extended drive error-recovery processes and are tested to 1 million hours MTBF. These EIDE and SATA drives include an 8 MB cache for faster time to data and Fluid Dynamic Bearings to reduce heat, vibration, and noise

Designed and manufactured to enterprise-class standards – provides enhanced reliability in high duty cycle environments.
RAID-specific time-limited error recovery – improves compatibility with RAID adapters; prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop hard drives.
1 million hours MTBF – meets enterprise-class reliability standards.
8 MB cache – provides a higher percentage of cache hits and significantly faster time to data than industry-standard 2 MB versions.
Fluid Dynamic Bearings (FDB) – improve hard drive reliability; reduce heat, vibration, and noise.

Ideal applications
Scientific computing
Enterprise backup
Document and image management
Video servers
File servers,
Web servers
E-mail servers.


IMPORTANT: Because of the time-limited error recovery feature, this product is intended for server applications and is not recommended for use in desktop systems.

What is time-limited error recovery and why do I need it?
Desktop drives are designed to go to great lengths to protect and recover data, at times pausing for as much as a few minutes to make sure that data is recovered. Inside a RAID system where the RAID controller handles error recovery, the drive does not need to pause for extended periods to recover data. In fact, heroic error recovery attempts can cause a RAID system to think the drive has failed and drop it out of the array. WD Caviar RE is engineered to prevent hard drive error recovery fallout by limiting the time the drive spends in error recovery. With error recovery factory set to 7 seconds, the drive has time to attempt a recovery, allow the RAID controller to log the error, and still stay online. Designed for portable digital devices of all kinds including notebook computers, external storage, car navigation systems, digital audio to GPS systems, blade servers, and tablet PCs.
