IntelliSeek optimizes seek speeds to enable lower power consumption, noise, and vibration. IntelliPower, according to WD, adjusts the balance of spin speed, transfer rate, and caching algorithms for optimal balance between performance and power consumption. StableTrac reduces vibration by securing the motor shaft at both ends, and this in turn permits accurate head tracking during read and write operations. The 2TB drive has several WD technologies inside that the company says enable this model to achieve its balance of price and performance. On each of those tests, its results were off those of our performance leaders by a dozen seconds or less. For example, it completed our “write files and folders” test in 112 seconds and our “write large files” test in 92 seconds. ![]() On other core metrics, though, the 2TB drive performed very competitively. ![]() This model lagged behind our performance leaders (the Western Digital RE3 Enterprise 500GB and the WD VelociRaptor) on some results–most notably, the write-intensive disk imaging test that we perform as part of PC WorldBench 6.
