REadyNAS NV (Infrant-- Not NV+)

I don't know if there is still a maintained harddrive compatiblity list for the old sparc devices.

But you should be able use most standard non-4k sector drives up to 2tb.

2tb is the maximum supported drive size.

The NV+ v1 is an evolutionary improvement over the NV.

If a disk works in the NV+ v1 it most likely would work in the NV too, but that may not always be the case.

As TeknoJnky mentioned the maximum capacity disks you can use are 2TB disks. So you could install 4x2TB disks.

There are 4k physical and logical sector alignment.

From 4.1.7 onwards we'd use 4k sector physical partition alignment but the disks must still have 512b logical sectors.

If you need 4k sector physical partition alignment you may wish to backup your data, verify your backup, update to 4.1.7 (or later), verify the update is successful, do a factory reset with the new disks in place and restore your data from backup.

If the partitions aren't properly aligned then performance esp. write performance may be poor.

4k logical sector alignment is only available for OS6 systems (on 6.2.0 and later, I think). So you can't use disks with 4k logical sectors in your NV.
