At the SATA-IO booth at Storage Visions, they have a functional demo of Western Digital prototype hybrid HDD/SSD's.

These are not hybrid in the traditional sense, as the SSD portion (128GB JMicron based controller driving Toshiba flash in the case of these prototypes) is logically separated from the HDD portion (a standard 4TB Black in this case).

Given that a SATA Express link can simultaneously pass a PCIe 2.0 x2 link in addition to a SATA 6Gbit/sec link, this one unit can link an SSD and an HDD simultaneously and independently. Above you see the standard SATA Express connector, and below is how those pins are connected at the drive itself:

Note the additional pins at what is usually the black side of the connector.

The rest of the connector is mostly a standard SATA connector that you are used to seeing.

At the demo, we saw a single 3.5" hybrid unit booting from the SSD portion and using the 4TB HDD for mass storage, all from the same device. The second demo had a separate boot drive and linked a pair of these prototype units in a dual RAID. Configured through Windows dynamic volumes, a RAID of the HDD's offered the increased performance you might expect from a pair of 4TB WD Blacks. The SSD portion of each unit was also RAIDed, and we saw their combined throughput as just over 1GB/sec. That was not much more than what a pair of RAIDed SATA 6Gb/sec SSDs would do, but realize this was being accomplished in addition to (and independently of) the HDD portions.

We were not allowed to start removing screws, but here's a look at the accessible portion of the logic board for this drive:

There is a JMicron controller paired with a single package of Toshiba flash. Toshiba has shown they can contain 128GB in a single package, so no problems there.

We're not sure where this technology is headed as the recent trend has been towards sticking with the standard SATA link for mass storage and M.2 SSDs plugged directly into the added port we've been seeing in many recent motherboards. We'll keep an eye on this technology moving forward, but for now at least we have seen it in the flesh and fully functional.

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.

Rumor: AMD Working With ASMedia on SATA Express

The new SATA Express (SATAe) and M.2 standards are hot topics in the storage world at the moment, and SATAe is one of the more interesting features of the new Intel Z97-based motherboards. Now it looks like it won't be long until AMD counters with support of its own. Well, kind of.

ASMedia is reportedly licensing their SATA Express IP to AMD for an upcoming platform. Didn't know that ASMedia already had a SATAe implementation? The ASUS Z97 Deluxe board which Morry recently reviewed uses an ASMedia controller for one of its two SATAe ports, along with one powered by the chipset.

We can only speculate on the "next gen" platform from AMD mentioned in the report, and it will be interesting to see what kind of performance numbers might be seen from this alleged product.

What is the ASUS Hyper Express SATA Express Drive?

Tagged: asus, hyper express, SATA Express

In this case the picture below is definitely worth 1000 words, it is easy to see just how ASUS created a RAID 0 in a single SSD.  Those SanDisk mSATA SSDs are both 128GB and communicate via a ASMedia ASM1062R controller.  Astute readers will wonder what this means for TRIM, as those commands often do not pass through a RAID controller and you are right to be concerned for as of yet TRIM is not supported on this drive.  Even without proper garbage collection the performance of this drive is rather tempting, as you can see for yourself in Legit Reviews full article.

"Last week we talked about what makes SATA Express important and showed off some performance benchmarks of the ASUS Hyper Express SATA Express External Enclosure. We’ve been able to acquire our own ASUS Hyper Express drive and we spent this week trying it out on our own systems to see how it performed on one of our own systems..."

PCIe SATA Express - Faster than the speed of NDA

Subject: Storage | May 1, 2014 - 07:01 PM |
Tagged: SATA Express, pcie, asus, ssd, Z97-Deluxe

KitGuru had a chance to test the ASUS Z97-Deluxe with a Concept Edition SATA Express SSD from ASUS to see what happens when you can feed the data from an SSD across two SATA ports, giving it the bandwidth of two PCIe lanes.  That should allow a theoretical 10Gbps bandwidth as PCIe 3.0 lanes are still being held in reserve as there are not that many available on an LGA1150 board but as KitGuru points out "leaked information suggest (we still cannot confirm anything) that M.2 support will be native to the ‘future Intel chipset’."  Check out their review and be prepared to be amazed that the speed of 728MBps was lower than expected.

"We revisit the SATA Express interface to obtain a more up-to-date look at what the next generation of SATA connections is capable of. Our tools for the job; a retail Asus motherboard set to release soon, and a concept version of Asus’ Hyper Express enclosure, internally powered by solid state storage."

... And It's Gone. SATA Express Canceled from Intel 9-Series

Subject: General Tech, Chipsets, Storage | November 12, 2013 - 04:37 PM |
Tagged: Intel, 9-series, SATA Express

Intel is preparing to launch several processors next year. For back-to-school, Haswell will return with new SKUs and a new 9-series chipset; in the holiday season, Haswell-E will arrive for high-end (high wattage) enthusiasts on the X99 chipset; and, just before 2015, Broadwell-K will be available for the mainstream 9-series desktop.

SATA Express will not be accompanying them.

The specification, which more than triples SATA 6Gbps's "up-to 600MB/s" bandwidth rating, will not be validated for Intel 9 Series chipsets. Intel was originally rumored to be its launch partner. The host connector accepts connections from both SATA (up to two per host connector) and PCIe-based (one device, up to two lanes) hard drives. Two PCIe lanes provides 2GB/s of bandwidth.

It seems like the real benefit is to allow internal drives be connected with PCIe speeds through a ribbon-cable. Currently Intel has not given a reason to pass on the standard.
