Faster dd for disk clone

Guys can anyone tell how can we do faster disk cloning

Below i found in google

1. dd if=/dev/sda of=/dev/sdb bs=4096 conv=noerror,sync

So adding "conv=noerror,sync " makes it faster looks against not adding it

2. Enable write cache activated (hdparm -W1 /dev/sda) then run dd ..


Is above correct ? Any other ideas ?


Thanks!

bs=512k is certainly faster than 4k

For larger files, somewhat around 200mb - 2gb i even prefer bs=4M.
