USB 3.0 Is Coming Out Soon With Many Benefits

USB 3 is now out everywhere. Because USB connections to external hard drives for backup are quite typical, this delivers a huge enhancement in speeding up the transfer. However as usual, you can find a few caveats for being on the leading edge of technology. The USB 3 ended up being a major hit at the CES exhibit in January of this year.

USB 2 possesses a speed rating of 480 mBits/s, which indicates about 57 megabytes per second. But those are mystical numbers given that the majority of users are lucky to obtain 25 megabytes per second and even that may be based mostly on file size. The new USB 3 is rated at 4.8 Gbit/s or 570 megabytes per second but that too is significantly beyond the true speeds we got through testing. Once again it's really dependent on file size and type but we did manage to reach 58 megabytes per second in a handful of tests.

So in the actual world our tests showed at least a doubling of speed and generally half the time period to copy the identical amount of data. In some instances where there were many bigger files (1 GB or above) we did get bursts of more than 80 megabytes per second however that was the exception to the average copy rate. But I'll take a 50% improvement in speed and generally a third of the time to copy files any day of the week.

Moving around big and dense files like graphics or music will get a very significant improvement. Video cameras and music devices will get a large enhancement in transferring files to a personal computer. Server class machines and big workstations created for AutoCad, video editing, and music will certainly get a large boost from the new USB 3 speeds.

Transferring my audio collection around has always been a great pain. I have above 55 GBs of music and waiting for it to copy is intolerable. Or performing a complete fresh back up of my primary workstation with more than 120 GBs may be about as much fun as watching paint dry. In testing the brand new USB 3 I obtained a huge improvement over both tasks and decreased the time well above two thirds which is a significant improvement.

Now for the not so great news regarding USB 3: they changed the connector side that goes to the device thus all your present USB 2 devices will never see the brand new speeds. And as far as I could find at the moment, you can find only a few flash drives and external hard drives that are completely USB 3 compliant. And this also implies you'll need the brand new USB 3 cable to hook up with any new device.

One concern with current and old motherboards is that they might be restricted by their bus interface data transfer speeds. The PCI Generation 1.0 is limited to 2.5 GB transfer rate so it does not matter how fast any connection is past that restriction. And the new norm for USB 3 is a minimum of a 5 GB transfer rate to be authorized. You will see an increase in speed but in no way obtain the maximum transfer rate with these older designs.

And you won't find USB 3 supplied in many new computers yet. You can find a couple of forward thinking firms like Startech who sell a PCI board having USB 3 connections for about $50. And a few computer companies are slowly adding USB 3 to their most recent computer versions. This is particularly essential for laptop computer users since the one way now to upgrade is to use a media card adapter.

Both HP and Fujitsu declared that they would likely be providing USB 3 on their brand new laptop computers. Western Digital was the very first out of the gate with a new model of My Book 3.0 external hard drive that also comes with a USB 3 PCI adapter in a bundle deal. Seagate has mentioned it will offer you similar external hard drives by middle of the summer 2010. And flash drive producer Super Talent is offering a 16 GB flash drive that is USB 3 compliant.

So should you wish to increase your file and data transfers, USB 3 will undoubtedly provide some real world advancements in transfer speed. And when the new computers catch up and provide USB 3, and all the device producers get the new USB 3 compliant designs in the supply line, it'll rapidly become the new standard.
