Samsung quotes a MTBF of 2,000,000 hours, which is significantly higher than mechanical drives. {lol:]
好像比传说中的1.5m小时更多啊

边上那颗小的总都认识的吧，好像还是DDR2

测试要测下的
对比的是带了32M SDR的memoright mr25

就用大家最喜爱的hdtune吧

HD Tune Pro 3.00

读看上去还不错

写入比较难看啊
不过有缓存确实比某些ssd好看多了

说一下，貌似这个测试是在sb平台上跑的
所以，磁盘性能偏弱，Mr25是同一个平台上跑的

thg同期也测了这个盘

SLC啊{lol:]
