1TB and 5400 rpm: Western Caviar Green vs Samsung EcoGreen
 

For a long time we hadn't seen any 5400 rpms but they have now made something of a come back. Western were the first to signal the return with its Caviar GP range launched in 2007, when it chose to make a virtue out of what had previously been slightly shameful.

However, the first tests showed that performances weren’t that far behind the 7200 rpm models and this with a significant advantage in terms of lower sound levels and energy consumption.

Not necessarily cheaper than their 7200 rpm equivalents, these 5400 rpm drives are an alternative with advantages and disadvantages that we’re going to analyse by looking at the ranges of two manufacturers, Western Digital and Samsung.
