WD's terabyte disk refresh
posted on 27 August 2008 09:00
Western Digital has announced its third-generation terabyte enterprise drive providing marginal improvements but no great changes.
The WD RE3 1TB and 750GB drives are said to have a 20 percent performance improvement over the previous generation. Indeed there is a 32MB cache instead of a 16MB one and WD says the drives have dual processors but there are no listed improvemernts in latency or seek time or transfer rate or rotation speed. So users probably won't notice anything there.
WD says the drives withstand vibrations better and the head fly height is dynamically modified. Also there is a multi-axis shock sensor and 4th generation RAFF vibration detection and correction, but the MTBF rating of 1.2 million hours stays the same, so where's the beef?
