With a 7200 RPM drive speed, 16 MB cache, and 3 GB/s SATA interface speed, the Western Digital Scorpio Black 320GB hard drive looks impressive on paper and had solid performance numbers in the benchmarks. The performance benchmarks also showed that the Scorpio Black 320GB (WD3200BJKT) was faster than the Scorpio Blue 500GB (WD5000BEVT), which is no slouch. The Scorpio black series is faster than the blue series without a doubt.

When it comes to hard drives noise is also an issue, and the WD Scorpio Black is fairly quiet with an average acoustics rating of 25dBA at idle and 28dBA during a seek operation. This isn’t much louder than the 24dBA idle and 26dBA during seek mode on the WD Scorpio Blue. It should be pointed out that the free capacity of the Western Digital Scorpio Blue hard drive is actually 298GB as shown above and not the rated 320GB.
When it comes to pricing, the WD Scorpio Black 320GB Hard Drive had can be found online for $89.99 shipped today. That means you are paying $0.28 per Gigabyte, which isn’t too bad.

In the end if you are stuck picking between the Seagate 7200.3 320GB and the WD Scorpio Black 320GB, you need to ask yourself which is more important: performance or warranty? The Seagate Momentus 7200.3 was the winner on the performance front, but when it comes to warranties the WD Scorpio Black carries a 5-year warranty compared to just a 3-year warranty on the 7200.3. You’ll have to flip the coin and make the decision on that one as it boils down to just that choice. The power consumption is even the same on both drives (seek power consumption is 2.1W on both brand drives), so these drives are really similar.
