MEGACLI Tool Command Summary

First, patrol reading

1, megacli-adppr-enblauto-a0, activate immediately.

2, megacli-adppr-enblman-a0 set into manual mode, need to use megacli-adppr-start–a0 to activate.

Native command Queuing (NCQ) optimizes the order in which read and write commands are made to the hard disk. The hard drive with NCQ technology will reorder the access addresses according to instructions after receiving the read and write instructions. For example, according to the instructions, the hard disk needs to access 330 sectors, 980 sectors, 340 sectors, because the data on the disk distribution location, the normal hard drive will be sequential access. After the NCQ hard drive to optimize the order, you can read 330 sectors, then read 340 sectors, and then read 980 sectors. The advantage of this is that it reduces the time that the head arm moves back and forth, making the data read more efficient while effectively prolonging the hard drive's life.
