WD Launches High-Performance Enterprise Drives

WD RE3 3.5-inch Enterprise SATA Hard Drives
1 TB, 1.2 million hours MTBF, 32 MB Cache, 7200 RPM
Generation 3: 20% faster, unparalleled reliability.
High performance enterprise SATA drives designed specifically for business-critical applications.

LAKE FOREST, Calif. - Aug. 26, 2008 - As the enterprise market for highly reliable, high-capacity storage continues to grow, WDR (NYSE: WDC) today added 750 GB and 1 TB WD RE3 SATA hard drives to its successful family of WD RET hard drives.

Perfect for demanding server and storage application environments, WD's RE3 750 GB and 1 TB high-capacity enterprise SATA hard drives combine 32 MB cache, enhanced vibration and shock tolerance, and deploy new electronics to increase performance approximately 20 percent and by as much 60 percent in high-vibration environments. WD RE3 enterprise hard drives also include improved reliability features that help protect the drive and the data stored on it, and run cooler and quieter than previous generation enterprise drives.

"WD continues to offer enterprise customers the best combination of features, optimum performance, and superior reliability that they have come to expect from WD," said Tom McDorman, vice president and general manager of enterprise storage solutions for WD. "With WD's extensive experience in previous generation enterprise drives, we continue to address opportunities based on our customers positive experiences with WD enterprise hard drives."

WD RE3 drives feature 1.2 million hours mean time between failures (MTBF), native command queuing (NCQ), time limited error recovery (TLER), and an extensive and enhanced testing process to ensure long-term reliability for demanding enterprise applications.

WD RE3 Features

StableTracT - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations. Visit the Web site at http://www.wdc.com/global/flash/index.asp?family=stabletrac to see StableTrac in action. Dual processor - Twice the processing power that results in a 20 percent performance improvement over the previous generation.

RAFFT technology - Resulting in up to 60 percent performance improvement over previous generation drives, WD's fourth-generation RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration simultaneously in real time for maximum performance in high vibration environments.

IntelliSeekT technology - Calculates optimum seek speeds to lower power consumption, noise, and vibration in active seek modes without degrading performance.

Multi-axis shock sensor - An additional third sensor has been added to RE3 models to detect automatically the subtlest shock events and to compensate to protect the data.

RAID-specific, Time-Limited Error Recovery (TLER) - Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. Third-generation dynamic fly height - With this next generation dynamic fly height technology, each read-write head's fly height is adjusted in real time for optimum reliability.

Thermal extended burn-in test - Extended burn-in testing with thermal cycling added to ensure only the most robust drives are produced as RAID Edition.

NoTouchT 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.

Price and Availability

WD RE3 1 TB (model WD 1002FBYS) and the 750 GB (model WD57502ABYS) hard drives are available now through select distributors and resellers. Manufacturer's Suggested Retail Price (MSRP) for the WD RE3 1 TB is $249 USD and the 750 GB is $199 USD. WD RE3 drives are covered by a five-year limited warranty.

>> 1.2 million hours mean time between failures (MTBF)

As calculated how? Did they run two of these drives for 140 years and take the average between when they failed? Or, did they hooked up five hundred drives, and the first one failed on the 100th day? In actuality, can expect your drive to fail anytime after the 100th day?

Drive manufacturers are misusing MTBF: They're taking a number that's actually telling them how many quick-dying lemons are in the test group and presenting it as some representation of the total life expectancy of the drive.

On a sidenote: My experience with performance of WD drives has been mostly positive. I only had one lemon from them and that was a manufacturer's refurb (Never buy re-furbed drives).

WD drives are usually priced better than the competition, but never *ever* count on getting your mail-in rebate back from them. I was denied rebates twice from their Indian-outsourced claims department with the explanation that I had bought the drives "outside the promotion dates" when it was a ONE DAY THANKSGIVING SALE and Circuit City printed all of the rebate information for me!

Western Digital: You really shouldn't make the profit of your rebate handling company dependent upon how much they make your customers dislike doing business with you. I actually bought Seagate drives for a year or two after that particular experience.

Wd has made some great drives.

As far as MTBF ratings go this statment is copied diredtly from the wiki for mean time between failures

Mathematically, the MTBF is the sum of the MTTF (mean time to failure) and MTTR (mean time to repair). The MTTF is simply the reciprocal of the failure rate,

\text{MTTF} = \frac{1}{\lambda}. \!

The MTTF is often denoted by the symbol \! \theta, or

\text{MTTF} = \theta. \!

Since failure rate and MTTF are simply reciprocals, both notations are found in the literature, depending on which notation is most convenient for the application.

The MTTF can be defined in terms of the expected value of the failure density function f(t)

\text{MTTF} = \int_{0}^{\infty} tf(t)\, dt \!


\int_{0}^{\infty} f(t)\, dt=1. \!

The MTTR can be similarly derived from the repair rate.

A common misconception about the MTBF is that it specifies the time (on average) when the probability of failure equals the probability of not having a failure. This is only true for certain symmetric distributions. In many cases, such as the (non-symmetric) exponential distribution, this is not the case. In particular, for an exponential failure distribution, the probability that an item will fail after an MTBF is approximately 0.63. For typical distributions with some variance, MTBF only represents a top-level aggregate statistic, and thus is not suitable for predicting specific time to failure, the uncertainty arising from the variability in the time-to-failure distribution.

On commercial product descriptions, the "MTTF lifetime" is the amount of time the product should last, assuming that it is used properly.

Well I need to get me one of these and a Raptor 300G
