Computex 2014: WD Shows SATA Express-based PCIe HDD

SATA Express is an interface to either connect a hard drive to PCIe lanes, or up to two drives via SATA. Obviously, PCIe bandwidth over a cable connection is the real draw. To use the full speed, however, the drive needs to be able to communicate over PCIe. Currently, the standard uses two PCI Express 2.0 lanes (1 GB/s).

Now that Z97 and H97 have launched, WD is set to show off the technology at Computex. The above image is apparently of a dual-drive product, containing 4TB of rotating media and 128GB of SSD memory. I am immediately reminded of the Western Digital Black2 dual drive which Allyn reviewed last November. That product crammed a 120GB SSD into a 2.5" 1TB HDD, which appeared to the system as two separate drives. The drive has "Technology Demonstration" written in red font right on it, but it could be a good representation of what the company is thinking about.

WD also asserts that their prototype uses standard AHCI drivers, for OS compatibility.

If you want to see this product in action, then -- well -- you kind-of need to be at Computex. At some point, you might be able to see it in your own PC. When? How much? No pricing and availability, again, because it is a tech demo.

Sure. If I'd like to see WD butcher the SSD market the way they are price fixing the HDD market I'd totally consider ever buying an SSD from them.

Ugh. Why? Besides trying to push this stop-gap PCIe SATA-Express platform before SATA 4, it makes no sense when HDD's can't even come close to saturating SATA 2.0, and I don't include burst read speeds.

Literally no point.

There has to be a point. The article right below this is about intel using PCIE slot, with NVM Express,to get much better SSD transfer speeds no? Since this drive has and SSD in it, it would benefit from more bandwidth?

Here is that link incase the order changes in articles.

needs a 1tb ssd and a 4tb hd that would be a dream product for me in a 3.5" form factor
