評價(jia)內存(cun)條的(de)性能指標一共有(you)四個：

(1) 存(cun)(cun)(cun)(cun)儲(chu)容(rong)量(liang)：即一根(gen)內存(cun)(cun)(cun)(cun)條(tiao)可(ke)以(yi)容(rong)納(na)(na)的(de)(de)二進制信息量(liang)，如常用的(de)(de)168線內存(cun)(cun)(cun)(cun)條(tiao)的(de)(de)存(cun)(cun)(cun)(cun)儲(chu)容(rong)量(liang)一般多為(wei)32兆、64兆和(he)128兆。而DDRII3普遍為(wei)1GB到8GB。 (2) 存(cun)(cun)(cun)(cun)取(qu)(qu)速度（存(cun)(cun)(cun)(cun)儲(chu)周(zhou)(zhou)期）：即兩次獨立(li)的(de)(de)存(cun)(cun)(cun)(cun)取(qu)(qu)操(cao)作之(zhi)間(jian)(jian)(jian)(jian)所(suo)需的(de)(de)最短時(shi)間(jian)(jian)(jian)(jian)，又(you)稱(cheng)為(wei)存(cun)(cun)(cun)(cun)儲(chu)周(zhou)(zhou)期，半導體存(cun)(cun)(cun)(cun)儲(chu)器(qi)的(de)(de)存(cun)(cun)(cun)(cun)取(qu)(qu)周(zhou)(zhou)期一般為(wei)60納(na)(na)秒至(zhi)100納(na)(na)秒。 (3) 存(cun)(cun)(cun)(cun)儲(chu)器(qi)的(de)(de)可(ke)靠(kao)性(xing)(xing)：存(cun)(cun)(cun)(cun)儲(chu)器(qi)的(de)(de)可(ke)靠(kao)性(xing)(xing)用平(ping)均故(gu)障(zhang)間(jian)(jian)(jian)(jian)隔時(shi)間(jian)(jian)(jian)(jian)來衡量(liang)，可(ke)以(yi)理解為(wei)兩次故(gu)障(zhang)之(zhi)間(jian)(jian)(jian)(jian)的(de)(de)平(ping)均時(shi)間(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)隔。 (4)性(xing)(xing)能(neng)價(jia)格比：性(xing)(xing)能(neng)主(zhu)要包括(kuo)存(cun)(cun)(cun)(cun)儲(chu)器(qi)容(rong)量(liang)、存(cun)(cun)(cun)(cun)儲(chu)周(zhou)(zhou)期和(he)可(ke)靠(kao)性(xing)(xing)三項內容(rong)，性(xing)(xing)能(neng)價(jia)格比是一個綜合性(xing)(xing)指標，對于不同(tong)的(de)(de)存(cun)(cun)(cun)(cun)儲(chu)器(qi)有不同(tong)的(de)(de)要求。
