USB 3.1 Spec Approved, Brings 10Gbps Speeds

[smeezekitty]

I love the march of science & technology. Let us just turn that into a sprint though.

I think this wouldn't really be a good thing.

It is already hard and expensive to keep up with technology. All we need is for it to get outdated even faster.

stevejnb, if our technology does not advance at a sufficiently fast rate to compensate for other changes such as human population increase and the decrease of some resources then the result will be recession, followed by depression, followed by apocalypse. What the hell is wrong with you? Go live in Talibanistan.

Ever consider that population increase was unsustainable?

That's the point. Many want a lightweight notebook to carry around. Then when they go home or to the office, plug it in a docking station with a high-power graphics card and a large monitor. Get the best of a notebook and a desktop.

Why don't you just have two computers/devices? Use a sync software like SyncToy or cloud storage like Skydrive, and you can have your cake and eat it too, without all the compromises of trying to create a gaming rig out of an ultrabook or carrying a Clevo around like it's an iPad. You don't have to choose one or the other. You can have both you know.

In the other news - 90% of consumers have no access to USB 3.0

USB 3.0 has a signaling speed of 5 gbps, 4 gbps total throughput, and ~3.2 gbps of usable. So hopefully with 3.1 we are talking about 6.4 gbps of usable throughput. Thunderbolt sounds far superior technologically, but the USB backwards compatibility has a usability advantage. Also keep in mind that USB up to 2.0 and SATA/eSATA are half-duplex, while USB 3.x, Thunderbolt, and SAS, are full-duplex.

Concerning what fast enough is, USB 2.0, with a signalling rate of 480 mbps, half-duplex, with a throughput of ~280 mbps, can't stay ahead of even the sorriest SATA hard drive. A Gig-E NAS can beat that. Gig-E cannot keep up with even a single 5900 RPM hard drive. USB 3.0 with a usable throughput of ~3.2 gbps can easily stay ahead of any single external SATA mechanical drive, but even two external 7200 RPM SATA drives can max USB 3.0. USB 3.1 with an anticipated throughput of ~6.4 gbps would remove the connection bottleneck for external SATA drives entirely. SSDs cannot produce more usable throughput than the capabilities of the 4.8 gbps half-duplex throughput of the SATA III bus they sit on.

Thus, we can say that if you have a multiple drive external storage array, such as a RAID-0, RAID-10, or RAID-5; USB 3.1 solves a performance issue that you are already experiencing. Currently, the only shipping solution is Thunderbolt.

Just, screw you USB 3.1. I use eSATA from now.

 

[danwat1234]

But will this be compatible with now reversible USB cables and jacks? I am thinking not. The times, they are constantly a changin

>But will this be compatible with now reversible USB cables and jacks?<

From everything I read, it is.

Please can we start having external gpu's for laptops...?

Your better off just getting a laptop with the best dedicated graphics your money can buy.
External GPU is stupid because it requires a external monitor to work instead of using the laptop screen.

That's the point. Many want a lightweight notebook to carry around. Then when they go home or to the office, plug it in a docking station with a high-power graphics card and a large monitor. Get the best of a notebook and a desktop.

There are laptops with quite good GPUs that are thin, light weight and have good battery life. They are a bit pricey compared to the bulky ones. However, once you pay the obscene price for a Thunderbolt dock then add a GPU you've made up the difference.
