WD have announced a new line of drives specifically designed for 24/7 home and small business network-attached-storage use – dubbed the Red Series. Initial release information suggests improved power consumption across the board as well as improved performance and modifications to make them more suitable for constant use. The vibration compensation is quite interesting – 3D Active Balance, to use their term – and there is also mention of intelligent error recovery to prevent the drive dropping from a RAID controller.
You can read more about the drives here. Our testing unit is in-house and we should have some numbers soon!
