請問海量外置大硬盤全盤對拷，有什麽方法最快？
試過直接拖，i7 16G內存 電腦 複製500G的數據需要半天，這樣拷貝3 - 5 T的數據就要好幾天了。 500000MB / 60MB每秒 / 3600秒每小时 = 2.3小时 这才是拷个500G数据应有的IO速度啊，3T怎么可能要几天 看你的拷法咯，普通文件顺带筛选就teracopy winrar打包，选择存储模式，然后再copy fastcopy 引用第1楼john于2012-10-22 19:08发表的:500000MB / 60MB每秒 / 3600秒每小时 = 2.3小时 这才是拷个500G数据应有的IO速度啊，3T怎么可能要几天 images/back.gif
這個算法沒錯，但是實際就是上不去60M不知怎麼的USB2.0最多就30多M，還有WINDOWS很奇怪，拷貝前的準備時間（正在準備索引）就十多分鐘。 用的usb2.0？ Ghost Robocopy /MIR a:\\ b:\\
不用谢 wtf，你用USB2.0还说个毛哦 引用第10楼Jet.Black于2012-10-22 20:06发表的:

WIN7自带ROBOCOPY，WIN XP自己要去MS网站上下一个ROBOCOPY 引用第9楼sblnrrk于2012-10-22 20:03发表的:
全插SATA，USB拷还WINDOWS自带的复制不就是折磨自己么 images/back.gif
外置硬盤只有USB呀 引用第13楼罗力于2012-10-22 20:07发表的:

ROBOCOPY速度可以到USB的极限。
优点是数据传输极其稳定可靠。
很多人都忽略了WIN自带的东西。
MS其实也算良心企业 拆了，sata直连 引用第10楼Jet.Black于2012-10-22 20:06发表的:

這個真得謝。。。 順便 MIR 是啥參數？ 引用第16楼罗力于2012-10-22 20:32发表的:

MIR是镜像参数，保证A和B一样。
比如要同步A目录和B目录的时候。
如果B里面有文件C而A里面没有，那么B里面的文件C将被删除。 引用第17楼Jet.Black于2012-10-22 20:36发表的:

简单的说就是用A的内容同步B了，A里面删掉的B里面也删掉。
ROBOCOPY最强大的地方是能复制NTFS权限，不过很少用到就是了

/COPY:copyflag :: what to COPY for files (default is /COPY:DAT).
(copyflags : D=Data, A=Attributes, T=Timestamps).
(S=Security=NTFS ACLs, O=Owner info, U=aUditing info).
/DCOPY:T :: COPY Directory Timestamps.

/COPYALL :: COPY ALL file info (equivalent to /COPY:DATSOU).
/NOCOPY :: COPY NO file info (useful with /PURGE).
/SECFIX :: FIX file SECurity on all files, even skipped files.
/TIMFIX :: FIX file TIMes on all files, even skipped files.
/PURGE :: delete dest files/dirs that no longer exist in source.
/MIR :: MIRror a directory tree (equivalent to /E plus /PURGE).
/MOV :: MOVe files (delete from source after copying).
/MOVE :: MOVE files AND dirs (delete from source after copying).
/A+: :: add the given Attributes to copied files.
/A-: :: remove the given Attributes from copied files.

我说这种大容量拷贝就算是不用SATA至少也要找USB 3.0去嘛，用USB 2.0那就是活受罪。 你用USB拷还抱怨个球，U2.0的话30Mps相当良心了好吧
拆盘然后fastcopy 大量小文件基本无解，上次复制10000张ACG图貌似卡了3小时。。。大概才20G左右。。。 ghost 我用7类双绞线，速度和电脑内部对拷差不多了，80M左右 OSX 恢复 没usb3好歹有个esata吧
