The PC world is quickly preparing for USB 3.0

News reports from Asia indicate PCs with USB 3.0 will be shipping to consumers before the end of 2009.

USB 3.0, with speeds 10 times faster than USB 2.0, will offer transfer speeds of up to 5 gigabits of data per second.  Manufacturers are expected to introduce a new generation of USB flash drives, external hard drives, and other devices that will make use of the significantly faster transfer speeds.

NEC Electronics is expected to lead the pack among companies adopting USB 3.0, with the company recently becoming the first to introduce a USB 3.0 controller.  The company began shipping host controller samples last month, and in September will begin manufacturing an expected one million units per month.

In 2007, Intel unveiled USB 3.0 during its Intel Developer Forum (IDF) conference, but was accused by AMD and NVIDIA of keeping the open host controller specifications a secret to create an unfair advantage against competitors.  Intel later released the open host controller specifications in November 2007, with companies expected about the increased speed of the technology.

There has been some talk about whether or not the PC industry will be ready for USB 3.0.  During the SuperSpeed USB Developers Conference, held two months ago in May, manufacturers outlined their aspirations to utilize the superior USB 3.0 -- devices also were shown to be faster than eSATA, which offers 3Gbits/s transfer speed.

NEC anticipates 140 million PCs will ship in 2011 utilizing USB 3.0, with that number expected to climb up to 340 million in 2012.  Microsoft Windows 7, which launches in October, will not support the standard at launch, but will add in support later.

Both home users and businesses will benefit by using the faster technology, with large-scale data backup becoming much faster thanks to the 5Gbit/s transfer speeds.  Expect external HDDs with increased storage capacity from Western Digital, Seagate, Iomega, and other companies specializing in storage.

I guess you didnt notice the much neater cables, wich made airflow better in the case.. also no more master/slave settings, just plugging in the drive.

"It took years before the benefits of S/ATA (increased bandwidth) were realized over IDE in the real world.....yet people still flocked to it because it was 150mbps instead of 133mbps or whatever."

No more Master/Slave setting!

Let the oppressed interfaces be free!!

Neatness is only esthetic, long forgotten once the side panel is on the case.

Better airflow is mostly a myth, air is not like light it flows around obstacles, and no passive heatsink will depend on direct inward flow from a front panel fan if the system is properly designed.

Even so, it is a small improvement over PATA's shortcomings and SATA did two different important things. It got us away from the sometimes fragile open IDC method of attaching connectors to ribbon cables, and it extended the length you could plug in two drives since an 18" PATA cable folded and routed neatly, then connecting to both a master and slave, wouldn't allow the slave to be very far away from the motherboard connector.

Not a big deal if you only have a couple of drives in the bottom of a case, quite a bit bigger deal if you want a HDD and an optical drive on the same cable but to have the HDD in the HDD bay instead of an upper 5.25" bay.
