CONCLUSIONS
Samsung EcoGreen F4 2TB
The newest EcoGreen is a huge improvement noise-wise over the disappointing F3. Measuring only 13 dBA and 15 dBA at one meter when idle and seeking, respectively, the acoustics of the 2TB F4 at last brings EcoGreen parity with Caviar Green. When it comes to power consumption, the 2TB F4 is actually superior to the 2TB Green, using almost 1W less when seeking, and it idles using the same amount of energy as the WD with its heads parked. (It should be noted however that the 2TB WD Green we are comparing it to is an older 4-platter model. Newer WD GP revisions have been shipping recently with three 667GB platters, which probably brings power down. We'll be checking on this soon.)
From a performance standpoint, like most "green" models, the F4 is relatively slow compared to 7200 RPM drives. Boot and loading times are a step behind, and when copying small files it can only beat 2.5" variants. Copying large files is the one area in which it excels, its one saving grace. We wouldn't employ it as a boot drive to hold an operating system and applications for daily use, but it is almost perfect for media storage. Retailing for between US$100 and US$110, it is also extremely affordable.
