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. That is, until I realized that its $.15 per gigabyte cost is actually fairly competitive with that of other drives on the market the only difference is that this particular drive’s supersize capacity skews the upfront costs accordingly.Western Digital has managed to fit 2TB of storage in a single hard drive. I also admit that, at first blush, the 2TB model’s $299 price tag gives me pause. But even though I like the idea of consolidating my data under a single roof, I shudder to think what the costs to recover a ginormous 2TB drive might be if anything should go amiss. Such a high ceiling on capacity means that I no longer need to make choices about where I’m storing my data instead, I can better organize and consolidate my data across multiple subjects. The storage fiend in me salivates at the thought of 2TB in a single 3.5-inch hard-disk drive. And WD’s NoTouch ramp-load technology keeps the recording head from touching the disk media. 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.
