Checked the hdd compatability list now and there is one 4tb drive listed there. could i change out all my drives to get 4x4tb?
That should work. The HCL is very old, and Netgear hasn't kept it up to date for a long time. I recommend WDC Red or Seagate Ironwolf for your new disks. They should both work well.
Your NAS should end up with a 12 TB (10.9 TiB) volume.
Note that your NAS does have two expansion limits:
a volume can't be expanded more to a size greater than 16 TiB.
a volume can't grow more than 8 TiB from it's starting point.
The first limit doesn't apply in your case, but the second one might. For instance if you had 1x3TB or 2x3TB when you first installed the NAS, then you will exceed it, and the expansion will fail when you add the last disk. If that happens, you'd need to do a factory reset with all disks in place.
so i should now easily be able to add one and one drive untill i have 16tb?
Yes (getting a 12 TB volume). Just make sure the resync is complete before you upgrade the next disk.
Also, reboot the NAS after you upgrade the second disk. You should get a prompt at the point, but reboot it even if you don't. Then wait for vertical expansion to complete before you move on to disk 3.
It doesent say anything. volume looks fine. I did see a thread from a while ago where a guy had the same problem but changed raid type and it stopped failing. Seeing as the new disk also gets channel 1 failed i am guessing the problem is on the NAS itself
Aah. So if would not get increased storage until i have 4x4tb? i now have 3x3tb and 1x4tb.
Aah. So if would not get increased storage until i have 4x4tb? i now have 3x3tb and 1x4tb.
Storage will increase by 1 TB when you upgrade the second disk. You'll grow from 9 TB to 12 TB when all are upgraded.
At the end of the second upgrade (resync) you should be prompted to reboot. If you aren't, then reboot anyway. After that the volume size should increase.
It is important to make sure the volume is fully redundant before you do that, so maybe you can give us a little more info on the channel 1 errors?
This is what the log tells me after the new disk insert.

I am wondering if all my drives start failing like this, that i instead of continuing to swap to 4tb drives which is the max of this unit, i may just as well get a new device and do 10tb drives.
A newer NAS would give better performance of course.
But drives will fail from time to time no matter what NAS you use. RAID will normally keep your data available, but it is not enough to keep your data safe.
