The WD Black2 Review: World's First 2.5" Dual-Drive
by Kristian Vättö on January 30, 2014 7:00 AM ESTPower Consumption
The idle power consumption comes out fairly high. Given that there are more components than in a regular SSD, I was expecting higher power draw but 1.32W is more than I would've thought. Note that this is SSD only -- the hard drive isn't even spinning, although its controller still draws some power. Since notebooks are the target market of the Black2, I would have liked to see some sort of low-power state support (HIPM+DIPM and DevSleep) or at least lower idle power consumption in general.
Load power consumption isn't nearly as bad. If the SSD and HDD are accessed simultaneously, the power draw is obviously higher than that of a single drive but not critically. If you ran a normal dual-drive setup, the power draw could easily be more than 4.5W anyway.

Ouch, that is one expensive drive. As you say, it appears to be the ideal solution for a laptop with only a single drive bay. I think there is another option - change the HDD for an SSD and put the HDD into the optical drive bay with an adapter.ddriver - Thursday, January 30, 2014 - link
It is kind of expensive and kind a slow and power hungry for an SSD, but still it is essentially 2 hard drives in one. I would actually get this if the SSD part was a tiny bit better. I don't think the presence of mechanical drive in the case mandates the SSD performance be any lower. I think I will just install an extra drive in the optical drive bay, seriously DELL what were you thinking who uses optical storage in 2012?lmcd - Thursday, January 30, 2014 - link
Me.Thanks Dell for considering :-)

Poor you :) I maintain about 20 TB of data, in the past the database was much smaller so I used to back it up on CDs, then DVDs, but the damn things are just too slow, unreliable, small and the cost of storage was very high. It was this moment I began hating optical storage with passion, my life got marginally better when I destroyed all optical disks and moved everything to hard drives - faster, cheaper, more compact and reliable.I know manufacturers provide installation disks which some people end up using for years, failing to realize the software on that disk is usually out of data before they even made the purchase.
And for all scenarios a hard drive is overkill there is the USB flash drive.
I guess optical storage makes some sense on consoles and/or media center PCs, if you watch many bluray or dvd movies, but for everything else... meh... and on that dell laptop it is just dead weight and battery drain.

Try blu ray man, blu ray's will match HDD's capacity in the near future. At present, it can already match SSD's capacity of 128GB.The blu ray tech is good up to 25 layers @ 32 GB per layer = 800 GB
Optical is far from dead when America has some of the worst bandwidth in the world.

So I'd need 5 Blu-ray discs per hard drive, which would take 15 hours to write at 16x speed.JHBoricua - Thursday, January 30, 2014 - link
But what happens when one of those 4TB drives fails? Assuming you have them in a RAID array, it will probably take as long or longer for the array to rebuild, not to mention that at those capacities, the risk of another drive failing during the rebuild are simply too great if you care about your data.ddriver - Friday, January 31, 2014 - link
I don't raid, I just backup. This is IMO better. I could raid something for performance but never for safety.name99 - Friday, January 31, 2014 - link
Jesus, You sound like iOmega with the endless succession of ZIP and JAZ drives, or Cringely talking up his aluminum foil based drive (which still has not seen the light of day).So the best Blu-Ray could do (in drives that don't exist, using disks that don't exist) is a very slow version of a drive that I can buy for around $50?
Good luck getting rich with that particular technology.
Optical is dead dead dead. And quit whining about "worst bandwidth in the world" you drama queen. Go to a real third world country and see what really bad connectivity looks like. The only problem most Americans have is that they will have to wait five minutes for their drivers to download rather than 20 seconds. That's just not enough pain to keep optical relevant.

you forget the very restrictive bandwidth caps, the terrible customer service, the awful reliability, the throttling of data, the list goes on.
