    More 500GB notebook drives: Seagate 7200.4 & Hitachi 5K500.B

    ConclusionSeagate Momentus 7200.4 500GB - We're at a loss to explain how this 7200rpm drive can be quieter than the 5400rpm Momentus 500GB with the same number of platters that we reviewed in the spring. Perhaps one or both of our samples are atypical — it's hard to say one way or the other without a few more samples of both models. Regardless, our Seagate Momentus 7200.4 500GB sample was surprisingly quiet, beating out the 5400.6 by 2~3 [email protected] It does vibrate a bit more though, making its overall acoustics similar to the WD Scorpio Blue 500GB. In a laptop, this difference may indirectly make it noisier than the 5400.6. The 7200.4 performs well, in league with some of the "green" desktop drives with reduced rotational speeds. It's a bit slower than most 7200rpm desktop drives, but the difference is not big. It also uses very little power, only marginally more than a 5400rpm 2.5" drive. As we reported a few days ago, inside a Scythe Quiet Drive 2.5, it is a cheap silent alternative to a solid state drive. Slower, for sure, but higher capacity than you could get from any SSD for even 10 times the price. Travelstar 5K500.B 500GB - Hitachi's half terabyte 5400rpm notebook drive is a nice addition to the available options for consumers. It's very quiet, matching the Momentus 7200.4 500GB sample vibrates very little, and is very modest in its power consumption. It beats out the other two 500GB 5400rpm notebook drives we've tested, the WD Scorpio Blue and the Momentus 5400.6, for both acoustics and power. Performance is similar, except for random access, which is a touch slower. We doubt the random access speed difference will be noticed in actual use, especially in a notebook computer. The Hitachi Travelstar 5K500.B 500GB and the Seagate Momentus 7200.4 500GB are both fine hard drives, whether used in a desktop PC or a portable, and can be confidently recommended, especially for any computer user who seeks to minimize noise.
