Iomega hasn't tweaked the OS since our last look at the px2-300d. The apps haven't changed, but here they all are in the All Features screenshot below.

Volume configuration is fairly unsophisticated compared to other RAID 5 NASes. First, there is no RAID level migration or expansion. If you want to do either, you need to delete the existing volume. Once you choose a RAID 5 or 10 volume, you'll need to wait a long time while it syncs. Full RAID 10 sync of the 8 TB review sample took 10 hours and 45 minutes!

The Drive Management screenshot below shows the volume creation options. Note the absence of drive select checkboxes and no RAID 1 option. So you can't create multiple RAID 1 or 0 volumes, nor can you create a three-drive RAID 5 volume with a spare drive. The None option actually creates a single JBOD volume with all four drives. The default for write caching is Enabled with UPS as shown, but you can also select Always enabled and Always disabled.

I found you can acutally create a RAID 1 volume, by pulling two drives. But you can't create two RAID 1 volumes or a mix of RAID 0 and 1. No matter how many drives you put in, you can create only one volume.

A few other competitive weaknesses remain including:

  • You can limit access to shares by user and/or group. But you can't control access by service. So you can't shut off FTP access to certain shares, for example
  • No iSCSI encryption or authentication and no target multiple connects
  • No IPv6 support
  • Unlike px-series NASes, the ix4 doesn't support volume or folder encryption.

If you want more screenshots of the ix4's features, check the ix2-dl review gallery.
