It speeds up reads and writes are at the same rate as writing to a single drive. There may be a imperceptable difference in single drive write and mirrored write to two drives on separate controllers. There will be a slow down writing to two drive on the same controller. Depending on the system (IDE, SATA or SCSI) the slowdown will be as bad a Nx (N is number of drives) for IDE, up to better performance with SCSI (<Nx) with SATA in between.<br>

Hi,<br>
<br>
Does RAID 1 slow down performance?<br>
<br>
Thanks,<br>
