新年第一帖:SSD
发表于 : 2012-01-01 9:30
最近买的mini电脑上配置了一块16G的KingSpec的SSD,但是并没有感觉到明显的性能提升。或许是这个牌子的SSD不行。但是除了性能以外,SSD的另一个优点就是安静和低能耗。如果是电脑在夜里也需要开着的,普通硬盘的噪音还是能听到的,而SSD则非常安静。
不知道大家对SSD的性能感觉如何。

从现在的SSD评测数据来看,比以前的提高了不少,关键还是价格啊leo 写了:看来还要等等,不过如果只是程序的问题,可能解决也会比较快。
taobao上搜了一下,这块板子要1999RMB?hyaska 写了:SSD主控很重要,固件更重要,而且容量大速度就上的去。没钱买,搞了个金胜的8G IDE接口的。
没风扇的主板,性能还可以的功耗低的,我又看中一块,是JETWAY的 NC9C-550,绝对完美,还支持RAID0,1 不需要自己在操作系统上改来改去的。
