在节能环保的风潮下，桌面计算机硬盘也向笔记本电脑看齐，开始强调省电性能。
日立（Hitachi）日前发表一款低耗电的桌面计算机硬盘DeskstarP7K500，其采用垂直录写技术，储存容量***高为500GB，转速7200rpm并采用SATA接口。日立表示，P7K500相比前一代产品可节省40%的用电量。
P7K500将单碟与双碟模式的运行耗电量分别降至6.4瓦和8.2瓦。令计算机每小时耗电量可低至50瓦，硬盘则只占7瓦或占整个系统耗电量的14%。P7K500将于2007年第四季度上市，售价未定。
无独有偶，日立并非***间推出省电桌面计算机硬盘的厂商。WD在今年七月，就宣布推出GreenPower技术。WD宣称透过此技术可让硬盘节省高达40％的电力。WD的GreenPower技术应用于3.5英寸硬盘系
列，容量从320GB到1TB不等。
另一间硬盘厂商希捷（Seagate）也在同时，宣布将一项名为PowerTrim的省电技术纳入桌面计算机硬盘BarracudaES.2。表示其能机动调整所有运作模式下的硬盘耗电率，使整体耗电量降低20%，每GB的耗电瓦数降低55%。
“过去大部分都认为笔记本电脑才需要省电；但是近年来，节电的诉求已经延伸到了桌面计算机，因为环保的关系，”日立技术支持协理蔡正平说。在过去，大部分人对桌面计算机硬盘的要求，仅在于容量和转速等规格而已。
蔡正平表示该公司拉低硬盘耗电量的原因并非改变使用材质。他指出关键即在于将桌面计算机硬盘向笔记本电脑硬盘看齐，添加了***能源管理功能。令P7K500在计算机待机时，将马达暂停运转，或者令读写头移开磁盘。使得硬盘不会持续运转消耗电力。可节省11%到44%的耗电量。
另外，一项已经出现在笔记本电脑硬盘中的HiVERT技术，也是用于帮助P7K500降低耗电。通过该技术，DeskstarP7K500增加使用线性稳定器以取代交换稳定器，提高电子装置的电压转换稳定性和效率。该硬盘并采用Tr***elstar的系统单芯片设计，进一步降低耗电量。日立表示，今后推出的所有桌面计算机硬盘Deskstar系列，都将具有上述所有省电功能。
