Oops, it seems that RAID-0 does not support on-line capacity expansion. You'll need to backup your data to external device, then reinitialize your NAS with the new disks. http://www.asustor.com/online/College_topic?topic=352&lan=en

Taking an external backup is a good option. But it will be very simple when we can directly replace smaller hard drive (2Tb) with a new bigger one (4 TB). When will RAID-0 support on-line capacity expansion?

I think there are no ways for this kind of expansion on RAID-0 volume. RAID-0 cannot afford any disk faults. If your volume is RAID-5, you can remove one disk out and insert a bigger disk. RAID-5 volume can handle one disk failure (when you remove one disk). Then system will rebuild this volume after a bigger disk inserted. After completed, you can replace another disk in this RAID-5 volume. One by one. How can you do with RAID-0 volume?

As @orion said, you can't do any capacity expansions with Raid 0, and you can only do it with Raid 1 by adding in a new disk to the array, so that means you have to have an open bay. And then you can only go to a higher level of Raid, such as 5 or 6.

You can get the full details of Raid expansions and migrations supported by most platforms here: https://www.asustor.com/online/College_ ... 352&lan=en

Keep in mind, this is not an Asustor limit, but a hardware limit based on the technology of Raid. All manufacturers are going to have these same limits.

I could first begin by doing a full system backup of your current 1TB HDD to an outside scource. You'll want so as to repair from this outside factor after your clean install of Windows on the 4TB HDD.

MODERATOR EDIT: This almost appears to be a spam post, due to the link and the fact that it references Windows. I will not delete the post, nor warn the user for spamming the forums, instead I will monitor the user's posts. If it is spam I will take appropriate action. Keep in mind, the OP is using a Linux based OS on the NAS which is definitely NOT running any version of Windows so the information in this post has almost nothing to do with the OP's or any follow up postings issues. I'm giving this post the benefit of the doubt.

Taking associate external backup could be a smart possibility. however, it'll be terribly easy once we will directly replace smaller Winchester drive (2Tb) with a brand new larger one (4 TB). once can RAID-0 support on-line capability expansion?
