Refer to the table below for an overview of the RAID modes available to the LaCie 5big NAS Pro. Note that the levels of performance and protection will differ based upon the number of drives in the volume. The New storage volume wizard includes a helpful tooltip with star ratings for performance and protection based upon the amount of disks in the volume.
|RAID Mode||Minimum Hard Drives|
|SimplyRAID||1 (no data protection) or 2 (with data protection)|
|RAID 1||1 (no data protection) or 2 (with data protection)|
The factory default RAID for an enclosure purchased with five hard drives is SimplyRAID with single-disk protection.
Understanding RAID and its many levels is critical when deciding how best to apportion the disks in your NAS. To help administrators configure their RAID volumes, LaCie NAS OS provides a handy star rating system with an intuitive storage capacity bar.
The last step of the New storage volume wizard provides:
All levels of RAID can be selected except for RAID 1, which is not compatible with volumes greater than three disks. Choose a RAID's radio button next to review its strengths and weaknesses in the center of the window. See the three examples below:
As the screenshots above show, RAID 0 is the best choice for storage capacity but it has a major weakness, no data protection. Both RAID 6 and SimplyRAID Double security offer data protection even if two disks fail. However, SimplyRAID optimizes storage capacity far better than RAID 6, giving users more space to store files.
