WD offers up 4TB home network storage

updated 08:50 am EDT, Tue September 30, 2008

WD ShareSpace

Western Digital today leapt into more serious home and SoHo network-attached storage with the appearance of its ShareSpace line. The four-bay system is designed to be simple, with a built-in iTunes server for sharing content over the network and pre-supplied backup software, but is also more powerful than the company's normal home drives. All ShareSpace boxes can run in either a RAID stripe for sheer space or a mirror for simple redundancy; a top-end model with all four bays full can also run in RAID 5 for a combination of backup and striping that makes the most of the available storage.

In addition to its usual local network backup features over gigabit Ethernet, the new NAS device can serve as an FTP server for remote access and carries three USB ports with different roles. While two back ports provide a straightforward route to expanding the capacity of the network drive, a front port lets users offload information from an external USB drive directly to the network without needing software or consuming bandwidth on the network.

The core ShareSpace unit sells for $700 with a total of 2TB of space spread across two drives and with drive rails for users to add more drives of their own; a $1,000 flagship model fills all four bays for a maximum of 4TB and comes preset to run in RAID 5 mode. Both arrays are already shipping and should be available today.

    Rather than spewing out the press release, please provide commentary and clarification for those that may not know better.

    4 TB on four drives with a RAID 5 will result in 3 TB of usable space (actually slightly less when formatting is taken into account as well.)

    Also, RAID is only there for physical hardware failure, since adding multiple drives into one logical volume exposes the user to hardware failure exponentially. RAID itself is not a backup, and will not protect your files from deletion, corruption, or infection.

    Doesn't sound like the PR

    Don't know where you're getting that impression, phayd!

    News articles don't have to be a recreation of How Stuff Works or a Wikipedia entry, especially not when this is probably the umpteenth device with RAID they've covered.

    "4 TB on four drives with a RAID 5 will result in 3 TB of usable space (actually slightly less when formatting is taken into account as well.)"

    2.7 TB give or take a few GBs actually.

    Yes, disk companies are guilty of some dishonesty when discussing their products. To these companies, 1 TB is 1000 GBs, but to your computer, its 1024 GBs. Then take into account formatting overhead RAID 5 redundancy and your left with considerably less than 4 TBs. Even a striped RAID format would yield only about 3.6 to 3.7 TBs, Still a nice amount of space, but they should be more realistic with their specs nonetheless.

    Maybe instead of complaining about the content, you should read the content first.

    4 TB on four drives with a RAID 5 will result in 3 TB of usable space (actually slightly less when formatting is taken into account as well.)

    That's nice. And 4TB on a RAID 1 results in less than 2TB of space. And using RAID 0, you get 4 TB of unformatted space.

    The point is, it isn't solely a RAID 5 device. In fact, only the 'high-end' even supports it. But all models support all three types.

    So the only way to describe it is by the total amount of space included, and the user determines how much they'll get based on how they decide to set it up.

    And furthermore...

    I re-signed up with MacNN just to reply to/with Testudo - love your work. I think that MacNN could have a "RAID explained" link, because this issue is relevant to all the NASs that will be popping up and non-techs never get 'where all the space goes'. RAID 5 is the new black :-)

    Of more concern is that the article says: " the new NAS device can serve as an FTP server for remote access". That's sort of true if you like using MioNet. And you run Windows. Many don't like MioNet and I would avoid a WD NAS because of it. Not just because of the Windows requirement, but that you are relying on Yet Another Company to supply this service rather than simply logging onto your NAS.

    Also, taking a look at WD's site, it says (of MioNet): "Share folders of data". Note the asterix. The asterix means: "Due to unverifiable media license authentication, the most common audio and video file types cannot be shared with different users using MioNet. A list of the non shareable file types can be found here. "

    You should read the list. Every sound and video format you can think of. What on earth is a "Farandoyle Tracker Music Module" and are people really pirating it? (apologies to Mr Farandoyle for dissing his format). This exclusion may apply to all of WD's products that use MioNet. It certainly does for their My Book World Edition products.

    Still, all this analysis may be beyond what a news site does, and more of a review.
