評價內存條的性能指標一共有(you)四個(ge)：

(1) 存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)容(rong)(rong)(rong)量(liang)(liang)：即一(yi)根內存(cun)(cun)(cun)(cun)(cun)(cun)條可(ke)(ke)(ke)以(yi)容(rong)(rong)(rong)納(na)(na)的(de)(de)(de)二進制(zhi)信息量(liang)(liang)，如常用的(de)(de)(de)168線內存(cun)(cun)(cun)(cun)(cun)(cun)條的(de)(de)(de)存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)容(rong)(rong)(rong)量(liang)(liang)一(yi)般多為(wei)32兆、64兆和128兆。而DDRII3普遍為(wei)1GB到8GB。 (2) 存(cun)(cun)(cun)(cun)(cun)(cun)取(qu)速(su)度（存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)周(zhou)期(qi)）：即兩次獨立的(de)(de)(de)存(cun)(cun)(cun)(cun)(cun)(cun)取(qu)操作之(zhi)(zhi)間(jian)(jian)所(suo)需的(de)(de)(de)最短(duan)時間(jian)(jian)，又稱為(wei)存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)周(zhou)期(qi)，半導體存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)器的(de)(de)(de)存(cun)(cun)(cun)(cun)(cun)(cun)取(qu)周(zhou)期(qi)一(yi)般為(wei)60納(na)(na)秒至100納(na)(na)秒。 (3) 存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)器的(de)(de)(de)可(ke)(ke)(ke)靠(kao)性(xing)(xing)(xing)(xing)：存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)器的(de)(de)(de)可(ke)(ke)(ke)靠(kao)性(xing)(xing)(xing)(xing)用平均故(gu)障間(jian)(jian)隔時間(jian)(jian)來(lai)衡量(liang)(liang)，可(ke)(ke)(ke)以(yi)理(li)解為(wei)兩次故(gu)障之(zhi)(zhi)間(jian)(jian)的(de)(de)(de)平均時間(jian)(jian)間(jian)(jian)隔。 (4)性(xing)(xing)(xing)(xing)能價格(ge)比：性(xing)(xing)(xing)(xing)能主要包括存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)器容(rong)(rong)(rong)量(liang)(liang)、存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)周(zhou)期(qi)和可(ke)(ke)(ke)靠(kao)性(xing)(xing)(xing)(xing)三項內容(rong)(rong)(rong)，性(xing)(xing)(xing)(xing)能價格(ge)比是一(yi)個綜合性(xing)(xing)(xing)(xing)指(zhi)標，對于不(bu)同(tong)的(de)(de)(de)存(cun)(cun)(cun)(cun)(cun)(cun)儲(chu)(chu)器有不(bu)同(tong)的(de)(de)(de)要求。
