We recorded a read speed of 50MBps and a write speed of 61.66MBps. We conducted some real-world testing as well, transferring 18GB of data between the Western Digital Caviar Green 2TB and our test bed PC, which uses a Western Digital Velociraptor (WD3000GLFS). (The burst rate is the highest speed that data can be transferred from the cache to the system.) By comparison, the Seagate Barracuda 7200.11 1.5TB scored a read speed of 94.6MBps, a write speed of 98.4MBps and a burst rate of 147MBps. This was demonstrated during testing with HD Tune Pro, which showed an average read speed of 78.1 megabytes per second, an average write speed of 77.5MBps and a burst rate of 126MBps. But that isn't to say the Western Digital Caviar Green 2TB is especially slow. There are faster hard drives, such as the Seagate Barracuda 7200.11 1.5TB. The drive has a formatted capacity of 1.81TB, delivering a competitive cost per gigabyte of 26 cents. It is equipped with a 32MB cache and has an interface speed of 3Gbps. The Western Digital Caviar Green 2TB has an areal density of 400 gigabits per square inch, and its four platters hold 500GB of data each. The Western Digital Caviar Green 2TB (WD20EADS) has a competitive cost per gigabyte of storage, although there are faster hard drives available. Western Digital has managed to fit 2TB of storage in a single hard drive.
