Habe mir zum Verteilen meiner Daten einen NAS geleistet (Maxdata SN40)

Dieser bietet auch ein RAID an (SW RAID 5 / 10 / 1 / 0) ... ?
Was bedeutet das ??


So sieht meine Auswahl aus:


Advanced : Disk Configuration


Your storage system can have up to four disks. Four disks have been detected. What kind of disk configuration would you like to use?

If you want to add more disks, install them one at a time and click Scan after each addition. Please wait until the disk LED is green before you click Scan.


- Data protection (RAID 5 - three disks minimum)
An amount of disk space equal to one disk is used for data protection, and the rest is used for data storage. The data is distributed in such a way that it can be recovered if any one disk fails.



- Data protection, failover (RAID 5+spare - four disks minimum)
Three of the disks provide RAID 5 data protection, and the fourth automatically joins the RAID if one of the other three disks fails.



- Data duplication (RAID 10 - four disks minimum)
Half of the disk space is used for data storage, and the other half is used for a duplicate (mirror) of that data. If one disk fails, you have a backup copy.



- Data duplication (RAID 1 - two disks only)
Half of the disk space is used for data storage, and the other half is used for a duplicate (mirror) of that data. If one disk fails, you have a backup copy.



- Better performance, no data protection (RAID 0 - two disks minimum)
All the disk space is used for data storage.



- Expandable, no data protection (Linear - one disk minimum)
All the disk space is used for data storage, and you can add more disks later without affecting your existing data.


Wenn ich kein Raid nutzen will, d.h. die 4 HDDs als "eine große" HDD gebrauchen will, was muss ich dann einstellen ??

Danke Euch
