I know that Buffalo Tech does not support what I am about to ask but i would like to know if this is even possible. I have a 2 TB / LS-WV2.0TL/R1 set up as a Raid 1. I am going to start running low on space so i want to swap out the 1TB drives for for 2 or 3TB ones. Can I swap one of the drives out and then rebuild the array and then do the same with the other drive? Any help would be great. I dont want to have to buy a whole new NAS unit when this one works perfectly well.

Yes you can, however once you rebuild the RAID (seperately on each HDD) you will need to delete/recreate the RAID to see the new capacity, this will obvious erase the data on the unit.

So rebuilding the array on the the 2TB or 3TB will be limited to the 1TB it is rebuilding from?

No, lets say you replace one of the HDDs with a 3TB HDD and rebuild the RAID.. fine, it will still only show the capacity of the original HDDs.

Then you replace the 2nd HDDs with a 3TB HDD and rebuild, it will still only show the capacity of the original HDDs.

Only when you delete and recreate the RAID after this process will it show the capacity of the new HDDs.

Understand?

Understood.

Will this work with HDDs larger than 3TB or is this unit limited to 3TB?

Thanks for you help.

I havent tested any thing larger that 3TB HDD so i cannot really answer this, technically speaking, if a 3TB disk works then there is no reason why a 4TB HDD wouldnt work as they would both use the 4k sector sizes.
