Acoustics
Both Red drives were incredibly quiet with the 1TB Red producing 12~13 dBA@1m and the 3TB model emitting about 1 dB more. Furthermore, the seek noise of both drives was indiscernible from one meter or even one foot away — we had to place our ear inches from the drives to confirm there was any additional noise at all. The two Red drives produced a slight tone at ~90 Hz, confirming that their motors spin at about 5,400 RPM.

The 1TB Red is on par with the last Caviar Green 2TB with both sharing the title of SPCR's quietest desktop drive. The 3TB Red meanwhile is clearly the quietest 3TB drive we've ever tested. The vibration level of the 1TB model was very good but not noticeably more prevalent than the the 3TB version. It's a common issue with single-platter drives with less bulky casings.
