Don't be afraid of PCIe or NVMe
In very early April, Intel put a shot across the bow of the storage world with the release of the SSD 750 Series of storage devices. Using the PCI Express bus but taking advantage of the new NVMe (Non-Volatile Memory Express) protocol, it drastically upgrades the capabilities of storage within modern PC platforms. In Allyn's review, for example, we saw read data transfer rates cross into the 2.6 GB/s range in sequential workloads and write rates over 1.2 GB/s sequentially. Even more impressive is the random I/O performance where the SSD 750 is literally 2x the speed of previous PCIe SSD options.
A couple of weeks later we posted a story looking into the compatibility of the SSD 750 with different motherboards and chipsets. We found that booting from the SSD 750 Series products is indeed going to require specific motherboards and platforms simply due to the "new-ness" of the NVMe protocol. Officially, Intel is only going to support Z97 and X99 chipsets today but obviously you can expect all future chipsets to have proper NVMe integration. We did find a couple of outliers that allowed for bootability with the SSD 750, but I wouldn't count on it.
Assuming you have a Z97/X99 motherboard that properly supports NVMe drives, of which ASUS, MSI and Gigabyte seem to be on top of, what are the steps and processes necessary to get your system up and running on the Intel SSD 750? As it turns out, it's incredibly simple.
Make sure you have enabled NVMe in the latest BIOS/UEFI. The screenshot below shows our ASUS X99-Deluxe motherboard used during testing and that it is properly recognizing the device. There was no specific option to ENABLED NVMe here though we have seen instances where that is required.

ASUS has announced a tiny new addition to their GTX 970 family, and it will be their most powerful mini-ITX friendly card yet with a full GeForce GTX 970 GPU.

The ASUS 970 DirectCU Mini card will feature a modest factory overclock on the GTX 970 core running at 1088 MHz (stock 1050 MHz) with a 1228 MHz Boost Clock (stock 1178 MHz). Memory is not overclocked and remains at the stock 7 GHz speed.

The ASUS GTX 970 DirectCU Mini uses a single 8-pin PCIe power connector in place of the standard dual 6-pin configuration, which shouldn’t be a problem considering the 150W spec of the larger connector (and 145W NVIDIA spec of the 970).

The tiny card offers a full array of display outputs including a pair of dual-link DVI connectors, HDMI 2.0, and DisplayPort 1.2. No word yet on pricing or availability, but the product page is up on the ASUS site.

There is an expression that states "everything is bigger in Texas," and that goes double for patent lawsuits. A company by the name of Internet Machines MC LLC recently lodged a complaint with the Eastern District of Texas for alleged patent infringement by a number of OEM manufacturers, system builders, and retailers of computers containing PCI Express switching technologies. Specifically, Internet Machines holds US Patent number 7,539,190, a rather generalized patent that covers multicasting in a shared address space wherein data is stored in a buffer and then forwarded to its intended port. The companies being called to court include PLX Technology, Alienware, Dell, Samsung, and others. While the computers that are assembled using PCI Express may well be utilizing switching technology, the fact that Internet Machines is going after system assemblers and retailers-- companies that work with computers but do not design and build the motherboards and other components themselves-- instead of the standards body that designs and maintains the PCI Express standard that everyone in the industry uses raises a question of integrity on the part of Internet Machines. Are their motives true in defending their patents, or is it the method of operation of a patent troll?
A diagram describing the patent in question
A system builder who wishes to remain anonymous contacted us with further details on the patent case in question. It seems that this patent showdown is not Internet Machines’ first rodeo. They have previously pursued other companies over US Patents 7,421,532 and 7,454,552 which cover switching with transparent and non-transparent ports. The case was settled in 2010, and it seems that Internet Machines (a seemingly no longer operating company) is not satisfied with the settlement. Internet Machines is moving for a jury trial in this latest round of lawsuits and concerns yet another data switching patent for PCI Express that covers multicasting in a shared address space. It widens the net further by including numerous system builders and OEMs that build devices that contain PCI Express technology but do not deal with the PCIe standard directly. How the company has been able to patent aspects of the PCI Express standard is unclear; however, they patent is worded in such an ambiguous way that it could apply to almost anything they wanted it to.
Beyond the ambiguous use of the patent system is the issue of targeting companies that have little control over the PCI Express specification to begin with. Our source worded it best in stating that PCI Express is a standard that everyone uses. The companies targeted by Internet Machines’ recent lawsuit do not manufacture motherboards or control the PCI Express standard. “We build computers, that’s it.” What are your thoughts on the issue?
