602T - switch from raid-1 to raid-0 without data loss ?

[xaveee]

Hi there,

I have been searching the net for some time to see how I could switch my 602T from raid-1 down to raid-0 to extend the data storage, but could not find any way to do it.

would anyone have a clue on how to do it without loosing any data ?

Thanks !
Cheers, Xavier

Hi,

ASUSTOR NAS dose support online RAID level migration and capacity expansion for certain RAID levels. However to migrate from RAID 0 to RAID 1 is not supported.
In your case, you need to backup all the dates on your NAS and then reinitialize the NAS to Raid0 or single.

Please be aware of that that a RAID 0 stripes the data across both of its component hard drives, which about 20% to 30% faster than you would get by using a single hard drive or RAID 1. However, the downside is that it does not offer any sort of data protection and you may lose all the dates once a single driver failed.

For more information, please see our college below:

Thanks a lot for the info.
Does it mean that both hard drives will be deleted (formatted) during the reinitialization process or will it just delete the configuration options ?

Thanks for the confirmation
Best, Xavier

unfortunately, yes ...

RAID-0 offers no redundancy protection at all, so if you lose a disk you lose all of your data

I see no practical reason why you would want to run RAID-0 on a NAS unless your use-case scenario is very specific.
