評價內存(cun)條的性能(neng)指標一(yi)共有四個：
(1) 存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)容(rong)(rong)量(liang)：即一根內(nei)存(cun)(cun)(cun)(cun)條可(ke)(ke)以容(rong)(rong)納的二進制信息(xi)量(liang)，如常用的168線內(nei)存(cun)(cun)(cun)(cun)條的存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)容(rong)(rong)量(liang)一般多為(wei)32兆、64兆和128兆。而DDRII3普遍(bian)為(wei)1GB到8GB。 (2) 存(cun)(cun)(cun)(cun)取(qu)速(su)度（存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)周期(qi)(qi)）：即兩次(ci)獨立的存(cun)(cun)(cun)(cun)取(qu)操(cao)作之間(jian)所需(xu)的最短時間(jian)，又稱為(wei)存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)周期(qi)(qi)，半導(dao)體存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器的存(cun)(cun)(cun)(cun)取(qu)周期(qi)(qi)一般為(wei)60納秒至100納秒。 (3) 存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器的可(ke)(ke)靠性(xing)(xing)(xing)：存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器的可(ke)(ke)靠性(xing)(xing)(xing)用平(ping)均(jun)故(gu)障(zhang)間(jian)隔(ge)時間(jian)來(lai)衡量(liang)，可(ke)(ke)以理解為(wei)兩次(ci)故(gu)障(zhang)之間(jian)的平(ping)均(jun)時間(jian)間(jian)隔(ge)。 (4)性(xing)(xing)(xing)能價格比：性(xing)(xing)(xing)能主要(yao)包括存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器容(rong)(rong)量(liang)、存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)周期(qi)(qi)和可(ke)(ke)靠性(xing)(xing)(xing)三項內(nei)容(rong)(rong)，性(xing)(xing)(xing)能價格比是(shi)一個綜合性(xing)(xing)(xing)指標(biao)，對于不(bu)同的存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器有不(bu)同的要(yao)求。
