USB 3.0 Is Coming Out Soon With Many Benefits


USB 3 is finally out everywhere. Due to the fact USB connections to external hard drives for backup are pretty typical, this gives you a huge enhancement in speeding up the transfer. But as usual, there are a number of caveats for being on the cutting edge of technology. The USB 3 seemed to be a major hit at the CES show in January of this year.

USB 2 offers a speed rating of 480 mBits/s, which means about 57 megabytes a second. But those are magical numbers given that a lot of users are lucky to get 25 megabytes per second and even that is dependent on file size. The brand new USB 3 is rated at 4.8 Gbit/s or 570 megabytes a second but that also is way beyond the genuine speeds we got during testing. Once once more it's really based on file size and kind but we did manage to reach 58 megabytes per second in a couple of tests.

So in the real world our tests exhibited at least a doubling of speed and usually half the time period to copy the very same amount of data. In some cases where there were lots of bigger files (1 GB or higher) we did get bursts of above 80 megabytes a second although that was the exception to the average copy speed. But I'll take a 50% increase in speed and often a third of the time frame to copy files just about any day of the week.

Moving big and dense files like graphics or music will see a really large improvement. Video cameras and music equipment will get a major enhancement in transferring files to a personal computer. Server class machines and large workstations designed for AutoCad, video editing, and music will without doubt get a large increase from the brand new USB 3 speeds.

Transferring my music collection around has always been a big pain. I have over 55 GBs of music and waiting around for it to copy is intolerable. Or undertaking a total fresh back up of my principal workstation with over 120 GBs could be about as much fun as watching paint dry. In testing the new USB 3 I got a significant improvement over both jobs and lowered the time well in excess of two thirds which is a major improvement.

Now for the not so good news about USB 3: they altered the connector side that goes towards the device thus all your active USB 2 devices will never see the new speeds. And as far as I could find right now, there are just a few flash drives and external hard disk drives which are completely USB 3 compliant. And this also indicates you'll need the new USB 3 cable to connect with just about any new device.

One difficulty with recent and old motherboards is that they may be limited by their bus interface speeds. The PCI Generation 1.0 is limited to 2.5 GB transfer rate so it isn't going to matter how quick any connection is past that restriction. And the new standard for USB 3 is a minimum of a 5 GB transfer rate to be certified. You will observe an increase in rate but in no way realize the maximum transfer rate with these older designs.

And you won't observe USB 3 offered in very many new computers yet. You'll find a few of forward thinking corporations like Startech who sell a PCI board with USB 3 connections for about $50. And some computer corporations are slowly adding USB 3 to their latest computer versions. This is notably important for laptop users because the sole way now to upgrade is to employ a media card adapter.

Both HP and Fujitsu declared that they will be supplying USB 3 on their brand new laptop computers. Western Digital was the very first out of the gate with a new version of My Book 3.0 external hard drive that additionally comes with a USB 3 PCI adapter in a package offer. Seagate has suggested it will provide similar external hard drives by mid summer 2010. And flash drive maker Super Talent is featuring a 16 GB flash drive that is USB 3 compliant.

So in case you wish to improve your file and data transfers, USB 3 will surely provide some real world improvements in transfer speed. And when the brand new computers catch up and offer you USB 3, and most of the device makers get the new USB 3 compliant versions in the supply line, it will quickly become the newest standard.
