When Asus asked us if we'd be interested in a reviewing their new, high-end USB 3 implementation that offered better performance than anything available elsewhere, we were skeptical. Historically, USB performance has been a function of which controller (Intel, AMD, NEC, Texas Instruments, VIA, etc.) was used. Asus claimed, however, that while you did need certain USB controllers to take maximum advantage of this new implementation, they'd built a solution that could accelerate transfer speeds on any third-party USB 3.0 (and even 2.0) controller. Customers don't need a specific brand of SSD or HD... Read more...
When Asus asked us if we'd be interested in a reviewing their new, high-end USB 3 implementation that offered better performance than anything available elsewhere, we were skeptical. Historically, USB performance has been a function of which controller (Intel, AMD, NEC, Texas Instruments, VIA, etc.) was used. Similarly, other types of products, like WiFi routers, have exceeded specified standard performance by using custom hardware. Companies like Linksys and D-Link for example, have offered enhanced operational modes, but only if you bought specific routers and wireless cards. But... Read more...
On paper, Intel's Thunderbolt looks like an easy winner over the relatively new USB 3 standard. The USB extension offers 10x the bandwidth of USB 2 and supports full duplex operation, but is limited to 'just' 5Gbps. Thunderbolt—even the cut-back, copper-wire version that's standard on new Macbook Pros—offers 10Gbps of bi-directional bandwidth. Intel's new standard is up to 4x faster than USB 3, but a new article at Extremetech argues that speed is far from everything. Thunderbolt, the article argues, is dangerously close to slipping into obscurity. As of this writing, Apple is the only... Read more...
USB 3.0 has been a popular feature ever since its introduction ~12 months ago, but a recent disclosure from Intel could slow the standard's march towards ubiquity. According to information released at IDF, Intel won't introduce a USB 3-powered chipset until 2012. This doesn't bode well for anyone hoping to buy an Intel platform that supports much in the way of upgrades. We already know existing Nehalem CPUs and motherboards won't support Sandy Bridge; it's possible Intel won't introduce native USB 3.0 support until Ivy Bridge. That transition shouldn't require new motherboards/sockets—Most... Read more...
Apple users often have to wait longer than us PC folk for top-end upgrades or features to become available, but this time the Macolytes might steal a march on the rest of us. According to rumors on the other side of the pond, the next-generation of iMac and Macbook Pro systems will feature both USB 3.0 and the heretofore dark horse candidate—FireWire 3200 (S3200). This new FireWire interface uses the same cable as the older FireWire 800 but offers four times the bandwidth. FireWire isn't discussed much these days, although the original IEEE1394a (FireWire 400) standard is fairly common, even... Read more...
USB 3 is one of the best standard updates the computer industry has come up with, but reports indicate Intel may not support the standard natively until 2012. That's particularly surprising since Intel designed much of the USB 3 standard—by all rights, Santa Clara should have been one of the first companies out the door, not one of the last. While it's still only found on a relative handful of motherboards, it's impossible to the performance difference between it and USB 2, even under modest test conditions. One of the most useful features of USB 3, though it's not something we've seen vendors... Read more...
Super Talent announced a new USB 3.0 Express RAM Cache drive. According to the company, the new drive will boost small block random performance by up to 110x over USB 2.0 speeds. The drive will come in 32GB and 64GB capacities and will be available in early July. Super Talent Introduces USB 3.0 Express RAM Cache™ USB 3.0 flash drive delivers Huge real world performance gains San Jose, California – June 1, 2010 – Super Talent Technology, a leading manufacturer of Flash storage solutions and DRAM memory modules, today announced the new “USB 3.0 Express RAM Cache™ drive”....

Waiting for new interface standards to actually be useful, is a bit like watching grass grow—in slow motion. The ratification stage can seem interminable, and the design, manufacturing, and deployment phases are the icing on Miss Havisham's wedding cake. Today's good news, for anyone waiting for USB 3, is that a host controller designed by NEC (µPD720200 if you're feeling geeky) has been officially certified as supporting SuperSpeed (3.0) USB. Cue applause.The host controller supports up to two USB 3.0 devices, and connects to the northbridge via a PCI-E Gen 2 link, as shown in the diagram... Read more...
According to Intel, it gets no respect. The company has spent "gazillions of dollars and bazillions of engineering man hours" on co-developing the new USB 3.0 spec and the commensurate USB 3.0 Intel host controller spec; yet Intel is perceived as wanting to keep USB 3.0 all to itself. At least that's the story that Nick Knupffer, blogger and Global Communications Manager for Intel, tells on Intel's Technology blog. Knupffer chose to use the Intel Technology blog as an opportunity for dispelling a number of rumors swirling around the development of the USB 3.0 spec. First up was the rumor that Intel... Read more...
