Samsung EcoGreen F2, 1.5TB: HD154UI
First goes a model from Samsung’s new EcoGreen F2 series which was one of the first series with 500GB platters to reach the market. The company’s previous economical series was released after the standard F1 DT line-up, but now Samsung follows the suit and, like the other makers, offers 5400rpm models first. However, these HDDs have all the characteristic features of the previous generations of Samsung’s products such as flight height control, a dual-core processor and a vibration sensor. This is in fact the obligatory minimum which is available, under different names, in products from all HDD makers.
As opposed to the others, Samsung does not produce 4-platter models, so 1.5 terabytes is the maximum capacity available. Besides the model with 32MB cache (this is the sample we have got for our tests), the EcoGreen F2 series includes its counterpart with 16 megabytes of cache.
Seagate Barracuda 7200.11, 1.5TB: ST31500341AS
The rather old Seagate Barracuda 7200.11 is the only model in this review to have a spindle rotation speed of 7200rpm. This HDD belongs to a transitional generation, actually. Its capacity of 1.5 terabytes is achieved by means of four rather than three platters (so the recording density is 375 rather than 500GB per platter). It is a kind of a reference point that we will compare the other models with.
