評價內存條(tiao)的性能(neng)指標一共有四個：

(1) 存(cun)(cun)(cun)儲(chu)(chu)(chu)容(rong)(rong)量(liang)：即一根(gen)內存(cun)(cun)(cun)條可(ke)以(yi)容(rong)(rong)納的二進制(zhi)信息量(liang)，如(ru)常用(yong)的168線內存(cun)(cun)(cun)條的存(cun)(cun)(cun)儲(chu)(chu)(chu)容(rong)(rong)量(liang)一般(ban)多為(wei)32兆(zhao)、64兆(zhao)和128兆(zhao)。而DDRII3普遍(bian)為(wei)1GB到(dao)8GB。 (2) 存(cun)(cun)(cun)取(qu)(qu)速(su)度（存(cun)(cun)(cun)儲(chu)(chu)(chu)周(zhou)(zhou)期(qi)）：即兩次(ci)獨立的存(cun)(cun)(cun)取(qu)(qu)操作之間(jian)(jian)(jian)所需的最短時(shi)(shi)間(jian)(jian)(jian)，又稱為(wei)存(cun)(cun)(cun)儲(chu)(chu)(chu)周(zhou)(zhou)期(qi)，半導體存(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)的存(cun)(cun)(cun)取(qu)(qu)周(zhou)(zhou)期(qi)一般(ban)為(wei)60納秒(miao)至(zhi)100納秒(miao)。 (3) 存(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)的可(ke)靠(kao)性(xing)：存(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)的可(ke)靠(kao)性(xing)用(yong)平(ping)均故(gu)障間(jian)(jian)(jian)隔(ge)時(shi)(shi)間(jian)(jian)(jian)來衡(heng)量(liang)，可(ke)以(yi)理解為(wei)兩次(ci)故(gu)障之間(jian)(jian)(jian)的平(ping)均時(shi)(shi)間(jian)(jian)(jian)間(jian)(jian)(jian)隔(ge)。 (4)性(xing)能價格(ge)比：性(xing)能主(zhu)要(yao)包括存(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)容(rong)(rong)量(liang)、存(cun)(cun)(cun)儲(chu)(chu)(chu)周(zhou)(zhou)期(qi)和可(ke)靠(kao)性(xing)三項內容(rong)(rong)，性(xing)能價格(ge)比是一個綜合性(xing)指標，對于不同(tong)的存(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)有不同(tong)的要(yao)求(qiu)。
