On the Difference between Western Digital ‘Elements’ and ‘My Passport’

tl;dr

  • The Elements line is a disk drive, less lardon software & services
  • The My Passport line & extensions has lardon software & services, and some colors.

Get Elements, you don’t need all that other goo.

    <quote>The RED drives don’t have RVS, they do have a “3D Active Balance Plus” feature that WDC claims reduces vibration. RVS is usually only found in enterprise-class drives, which are quite a bit more money than the REDs.</quote>

Maybe … sounds a bit facile.  What about the ARM-based units?

ReadyNAS Product Line Comparisons

These guys have a fantastically complicated product line.  It’s been around since Ajump, Infrant; NetGear now runs it.  It’s never quite clear what you’re buying and whether the box-on-the-shelf in front of you (or in the online store) is current or discontinued or what.  The published specifications are a little vague on a lot of the high-end capabilities.  Unfortunately, that means you “learn by experience” when you buy a unit and discover the user base / feature set that the model was tuned for.  Drive one before you buy one; good advice in all realms.

ReadyNAS NV+ (v1, sparc) is discontinued, there will be no IPv6

There is no IPv6 for the ReadyNAS NV (v1)
Question: what firmware update will supply it.
Answer: no such update will ever exist.
Reference: IPV6 support for NV+; By mdgm; In the ReadyNAS Community Forum; 2012-07-04.

Therefore: avoid the ReadyNAS NV+ (v1, sparc)

Stick with ReadyNAS “Ultra” or “Pro” (v2, x86, Atom)

NETGEAR ReadyNAS Ultra 6 RNDU6000

Folklore

NFS Support

The ReadyNAS NFS “just works.”   This is unlike the Western Digital ShareSpace which has weird omissions that cause application-level problems; some are showstoppers.  ReadyNAS NFS has:

  • NFS v3, tcp
  • Appropriate NFS protocol negotiation at mount.
  • IPv6 seems to be “enableable” on the RNDU4000 (unclear what that means).
  • NFS v4 from a Fedora client’ has

Root Access

  • Configurable to add no_root_squash from the (FrontView GUI)
  • Configurable to a CIDR network; e.g. 192.168.135.0/24
    BUT this seems to have been removed on RAIDiator 5-series as experienced on the ReadyNAS NV+ v2 (RNDU4000-200NAS)

SSH Access

  • Available, by factory add-on, but untested
  • Voids warranty, apparently
