(More customer reviews)(Note: My review is Mac based, but the Western Digital ShareSpace 4TB 4-Bay NAS RAID supports PCs and Linux as well.)
My history with SOHO NAS so far hasn't been all that good. The WD ShareSpace is the third NAS type device I've owned. The previous two (a 1 TB WD MyBook Pro II used as a NAS device through my Apple Airport Extreme and a 2 TB OWC Raidon NAS/RAID) were both returned. The WD MyBook Pro II had a drive sleep issue with the Airport Extreme. (See below.) The OWC Raidon NAS/RAID couldn't set user permissions properly running as a Mac formatted drive. As for the Western Digital ShareSpace 4TB 4-Bay NAS RAID, so far it appears to be the best of the lot.
After completely setting up the drive yesterday evening (in no more than an hour), overnight I did a complete restore of the 60 GB or so I have backed up of our home business data to the WD ShareSpace. It was seamless. When I woke up this morning all the data was there just as it should be. Then I copied my 47 GB iTunes library over from my Mac Pro to the ShareSpace Public:Shared Music folder. (The shared folders are created by WD and ship with the drive.)
So what do I have?
* Effectively in RAID 5 I have 2.68 TB of available storage (my 60 GB barely touches the surface.)
* I have access to my entire iTunes library from every Mac and PC in the house
I can now have an iTunes server without having to have a Mac acting a server or buying another separate device. The ShareSpace can handle multiple audio streams over the 1 GB/s NAS interface without breaking a sweat. (I have read in the WD FAQ that there is an issue with multiple audio streams and simultaneous file downloads, but I haven't run into this issue yet.) The only downside is, while you can access all the music (including MP3s and DRM AAC,) you can only run iTunes in List View, not Grid or Cover Flow. That's a bit of a bummer, but I expect that this is more of a limitation of iTunes than it is of the ShareSpace.
* Access as Administrator to all the drive shares.
At first this might not sound like a big deal. But unlike my Windows 2000 Advanced Server, all the previous NAS drives I've owned to date wouldn't allow me to access shares that I don't "own." My wife's share, for example, was not accessible to me. So why would I want that anyway? Simply because it makes backing up the entire NAS so much easier. What I've had to do in the past to access all shares for backup was to physically disconnect the NAS drive from the network and attach it via the USB port to my Mac Pro. Doing so overrides the read/write privileges of the NAS because now it appears as just another external drive attached to the Mac Pro. I did my backups and then had to eject the drive from the Mac Pro and reconnect it to the network. It was a bit of a pain. The ShareSpace overcomes this by allowing me to apply Admin privileges to my user account. Now when it's the weekly backup time I can simply mount all the shares on line and do the backup in one fell swoop.
* A green device
To save energy, the ShareSpace spins the four drive's speed down when they are not being used. This is a big improvement over the MyBook Pro II. I wound up sending it back because it completely shut down the drives when they weren't in use and the Airport Extreme couldn't wake them up again.
* A very quiet RAID/NAS
The drive runs very quietly. I can barely hear the fan. If the home office is dead quiet and I get right up next to the ShareSpace, I can hear the clicking of the drive heads as they read and write data--but that's completely tolerable. The Mac Pro, no noise generator itself, is louder than the ShareSpace.
I haven't done any file transfer performance testing yet. However, I do find that the device does well delivering streamed audio (and probably streamed video as well.) From what I've read and experienced with very large file transfers, it doesn't appear that WD hasn't put all that much oomph into the network driver and interface. (Yes, the ShareSpace does support Jumbo Frames over Gigabit Ethernet.) For now I don't plan to post-process any of my RAW files in Photoshop or Lightroom 2 on the ShareSpace. I'll leave that task up to the internal SATA drives in my Mac Pro.
The bottom line may be that the WD ShareSpace is a flexible, easy to manage device with tons of storage. But if you are looking for an absolute speed demon RAID/NAS this may not be your first choice. Pros:
* Great, great management tools via the web interface.
* Pretty decent management security (log in and HTTPS.)
* Tons and tons of on-line storage.
* RAID 5 capability.
* Very easy drive discovery.
* Bonjour spupport means that there is no need to guess what DHCP IP address has been assigned to the drive.
* No need to be an IT expert to manage the drive.
* Flexible and straightforward account and share management.
* Easy, easy, easy to use.
* 4 TB of RAID 5 for a decent price. Are you kidding me?
* Mostly all metal construction (how rare is that these days?)
* Stable drive enclosure that won't slide around on the desk or table easily.
* Design is okay. A bit techy looking, but it won't offend anyone either.Cons:
* I'd prefer to have an integrated power supply, although the brick power supply is better and more rugged than most I've seen.
* Let's have "real" documentation included. The "Quick Start" documentation is anemic. The on-line documentation is okay, but it has to be printed for a device this expensive and flexible.
* Virtually no software included. They include a backup application and the documentation on a CD. That's about it. But, to tell the truth I'd rather spend my dollars for the hardware and not for software "throw ins."
* Failed (or added) drive must be Western Digital drives. No other vendors are supported. Boo!
* Case opens like a PC. This is not complex matter, but drive access could have been made easier. (How about a door that swings open? Other vendors have done just that.)
* Drives are not hot swappable.
* File transfer speeds may be on the slow side.Overall so far: Most of the cons are nits or easy to live with. Highly recommended. All-in-all a very excellent way to provide RAID/NAS for a SOHO environment.
