評(ping)價(jia)內存條的性(xing)能指(zhi)標一共有四個：
(1) 存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)容(rong)量：即一根內存(cun)(cun)(cun)(cun)(cun)(cun)條可(ke)(ke)以容(rong)納的二(er)進制信息量，如常用的168線(xian)內存(cun)(cun)(cun)(cun)(cun)(cun)條的存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)容(rong)量一般多為32兆、64兆和128兆。而DDRII3普遍為1GB到8GB。 (2) 存(cun)(cun)(cun)(cun)(cun)(cun)取(qu)速度（存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)周(zhou)(zhou)期）：即兩次獨立的存(cun)(cun)(cun)(cun)(cun)(cun)取(qu)操作之間(jian)(jian)(jian)所需的最短時(shi)間(jian)(jian)(jian)，又稱為存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)周(zhou)(zhou)期，半導體存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)的存(cun)(cun)(cun)(cun)(cun)(cun)取(qu)周(zhou)(zhou)期一般為60納秒至100納秒。 (3) 存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)的可(ke)(ke)靠(kao)性(xing)(xing)：存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)的可(ke)(ke)靠(kao)性(xing)(xing)用平(ping)(ping)均故(gu)障間(jian)(jian)(jian)隔(ge)時(shi)間(jian)(jian)(jian)來衡量，可(ke)(ke)以理解為兩次故(gu)障之間(jian)(jian)(jian)的平(ping)(ping)均時(shi)間(jian)(jian)(jian)間(jian)(jian)(jian)隔(ge)。 (4)性(xing)(xing)能價(jia)格(ge)比：性(xing)(xing)能主要包括存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)容(rong)量、存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)周(zhou)(zhou)期和可(ke)(ke)靠(kao)性(xing)(xing)三項內容(rong)，性(xing)(xing)能價(jia)格(ge)比是一個綜合性(xing)(xing)指標，對于不同(tong)的存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)有不同(tong)的要求。
