I thought it would be useful to start a discussion to get people's views. I have been looking for fast and reliable HDDs for my new DS410j. I provisionally decided on Seagate Barracuda 7200.11 1.5TB but then I spotted several reviews which indicate that this drive is hit and miss. Other drives like the Samsung HD153WI and Western Digital WD15EARS are reliable but relatively slow. Can anyone suggest a drive that ticks both boxes without costing the earth?
