MonsterZero the problem with all of your points is that you have completely missed the point of this product. You are certainly entitled to your opinion and we even appreciate you discussing your thoughts with us. That said I do feel you have missed the point of this product and I will now try and explain why…
You first said “If cost per GB is your main concern just stick to 1TB drives in your server rack of a tower. If you want the performance of an SSD, go get one.” That statement right there shows you have missed the point of this product.
From the first paragraph of the conclusion…
“The WD Black2 is designed specifically as an upgrade for laptops with a single drive bay and it's somewhat pointless in any situation where separate SSDs and HDDs can be used in tandem. People who fit the usage case ultimately have a choice between one storage tech or another, and this is where the Black2 presents itself as a viable option -- the only option, in fact, as no other product offers what it does.”
So as you can see this product is not designed for a server rack or a tower PC, it is designed for laptop users limited to one drive bay slot. In other words it’s for users that can’t simply install a hard drive and an SSD separately.
You also said “Hybrid drives lack the throughput of an SSD, they are not even close. 140mb/s VS 550mb/s - how can you look at those figures and not realize what a waste of money this is.” This is not a hybrid drive, it’s an SSD and a HDD in the one package. Yes the SSD is slow compared to modern high-end solutions but it is still worlds faster than the fastest HDD’s out there and that is kind of the point.
No idea why you are questioning reliability. No one knows how these will perform over time but if WD’s track record is anything to go by the Black2 will offer excellent reliability.
Finally if you think the Black2 is a waste of money at $159 … well I don’t even know what to say really. At that price it would be a must have item for all laptop users and even some desktop users.
