The drives are also quieter, said WD. The WD Caviars at 320GB have started shipping this week, while the Caviar SE320 will be in the shops next month, it said. The firm is taking pre-orders for these drives, and said if you buy by the end of the year, the units will be shipped free. The suggested price for the SE320GB is $249.
Other improvements have also been added to the drives, including better caching algorithms.
