The WD Black2 Review: World's First 2.5" Dual-Drive
by Kristian Vättö on January 30, 2014 7:00 AM ESTRandom & Sequential Performance - HDD
The HDD performance is average, though that shouldn't surprise anyone as there hasn't been any major breakthrough in hard drive technology. The performance is still dictated by platter density and spindle speed, which puts the Black2 at the upper end with its two 500GB 5400rpm platters. I should note that as there is no way to test the hard drive partition of the Black2 as a raw disk like we usually test drives, I had to create an NTFS volume for testing. It's possible that there is some OS prefetching/caching going on, giving the Black2 an advantage especially in the random IO tests.

Hmm yeah you're right, I didn't know this was priced so high at $290 and 1TB SSDs are in that $500-600 range now from what I've seen.This would probably need to drop down to ~$180 to be worthwhile, based on pricing of a 120SSD ($80ish) and 1TB 2.5" HDD ($80) with a small premium for combined slot.

This is a bit silly. If they had gone to the trouble of merging the two into a single logical unit, it would make more sense.As you rightly pointed out - it makes little sense to anyone. If you need more space, you can do that in so many other ways...
This needed to be like the Fusion drive or it's DOA.

Dead on Arrival. Device makers don't believe that consumers can handle a file manager. WD thinks people want to separate their files between a hard drive and a SSD?mikato - Friday, January 31, 2014 - link
I'm not giving it to my parents, that's for sure. They only get single drive systems. It may be an SSD if they keep dropping in price.speculatrix - Thursday, January 30, 2014 - link
Am I the only person who on seeing the picture of someone holding the nSATA card by its connector thinks "well, that's part ruined... likely to die early from ESD, or corrosion on the edge connector"?Gigaplex - Thursday, January 30, 2014 - link
The devices held like that for marketing purposes are often defective parts already.Gasaraki88 - Thursday, January 30, 2014 - link
I'm not seeing the point of this drive. Why don't I get a 128SSD and a 1TB drive separately?Gasaraki88 - Thursday, January 30, 2014 - link
They should have made this a hybrid drive. That would have been awesome, 128GB SSD cache with a 1TB spinning disk.kmmatney - Monday, February 3, 2014 - link
The Seagate Momentus XTs are already pretty nice with an 8 GB cache (I have 2 of the older models with 4GB cache, and even those are "pretty good"). So a hybrid with this much cache could be awesome. I don't think the hybrid drives cache writes, so that would limit performance. I'm on the fence with this - I think it needs to be priced around $200 to be more interesting.mr_tawan - Thursday, January 30, 2014 - link
Some people on a laptop does only have 1 bay for 2.5" drive available, with no mSATA socket whatsoever. Given that larger SSD is still quite expensive, you might have to choose between having a speedy system with no room for storage, and a plenty of space but slow as snail.These people might go with SSD and a USB3 HDD, of course, but carrying another external drive makes the system bit less mobile.
If the laptop has optical drive, then you might swap it with a 2.5" drive caddy. But it does not, well this might be a good option.
Too bad the drive does not really perform, and it's pretty pricey. I'd have gone with a drive caddy and a external bluray drive :-(.
