Western Digital's line of Caviar GP have been considered by many as a value-grade hard drive because of its low price. However, nothing can be further from the truth.
Recently, we picked up a 500 GB model for our tests and we were most impressed with its performance. Not only did it deliver a large storage capacity using only two platters, it also delivered very good performance numbers. For more details, take a look at our comprehensive review.
"The use of perpendicular recording technology allowed Western Digital to deliver a storage capacity of 500 GB using only two platters. Fewer platters mean lower costs and lower power consumption. The high areal density achieved using perpendicular recording also greatly increased its platter-to-buffer transfer rate. Little wonder how it did so well in our benchmarks."
