试求 Pipeline 和 绿盘 之间的噪音对比评测

究竟哪个更静音，我想大家都想知道吧。。。

无绿盘帮不了你， 看了泡泡上的文章 有一点绿盘功率比Pipeline大

摘自SilentPCreview:

Subjectively, the overall noise level of the Pipeline HD Pro was very close to that of Western Digital's 1TB Green Power. We never had the opportunity to measure a GP in our anechoic chamber, but our vibration and power consumption figures are still valid. The Pipeline was very quiet, but as a 7200 RPM drive, it simply could not compete with a GP running at 5400 RPM when it came to vibration and power efficiency.


简单翻译:

Pipeline HD PRO的噪音水平和1T绿盘非常接近. 虽然我们没有机会实际测量绿盘的噪音,但是震动和功耗测试是仍然有效的. Pipeline是一款非常安静的硬盘,但是它没法和5400转的绿盘相比,尤其是在震动和功耗方面.

附上功耗对比:
Pipeline HD PRO(ST31000533CS): 空闲7.1W, 寻道10.1W
绿盘(WD10EACS): 空闲5.7W, 寻道7.5W

附上Pipeline的噪音值:
Airborne Acoustics(dBA@1m): 空闲13, 寻道16

补充一下,最后的结论是pipeline是7200转硬盘里面相当安静的一款,突发速度超过230M,持续速度也超过100M,但是因为该款硬盘专为大数据量流媒体(录像机,播放器)设计,所以寻道时间达到了17ms.,并且cpu占用率相对较高.
