USB 3.0 is hidden in the shadows for a while, but finally here. Slowly but surely, computers with USB 3.0 on board are emerging from his hiding place and land at retailers, such as new external hard drives and accessories.

To see how quickly the new USB specification is actually picked up Tom’s Guide N61Jq-X1, multimedia entertainment laptop from ASUS. The last entry in the series N61 has integrated USB 3.0 and benefits from ASUS that is 10 times faster than USB 2.0. To test the speed of USB 3.0 hard drive is in fact the couple N61Jq-X1 with two external USB 3.0 devices: Seagate 500GB BlackArmor PS 110 to 1 TB and 3.0 Western Digital MyBook. The first uses a 2.5 “disk, while the My Book is a 3.5″ drive. Both drives spin at 7200 rpm.

Sound good?

Before going down to numbers, let’s talk about USB 3.0. What is the problem? Well, in addition to being nearly a decade after the launch, USB 2.0, 3.0 is supposed to be capable of reaching speeds of 10 times that of USB 2.0, a rate of 5 Gb / s, compared to 480 Mb / s. This results in theoretical transfer rate of over 400 MB / sec. In addition, USB 3.0 sends more than twice as much energy for what is billed, if your next USB powered MP3 player does have to charge for maybe 30 minutes instead of an hour. Finally, USB 3.0 is more efficient because the ports can enter a power saving sleep mode when not in use. All very well, especially the transfer rate, but only when tested between two USB 3.0 external hard drives and N61Jq-X1 know how fast the new specification really is. Read the rest of this entry »

If you are looking forward to increase the USB 3.0-based external storage devices for speed to your system, you can keep your horses in the early test models shows that eSATA the edge for now.

As in the case of CrunchGear reports that tests show the first generation of USB 3.0 external storage devices increase in some impressive speeds with USB 2.0-based devices - almost tripling top speed, for example. While it is good news for external storage of users, so the comparison does not end point - that a similar eSATA device was third again so quickly to the USB 3.0 version with almost 33MB / s.

The figures offered by CrunchGear has been connected using HD Tune Pro benchmark for a number of storage devices are achieved - 5400 Seagate internal SATA baseline, a PS110 on both USB 2.0 and USB 3.0 connection and a free agent Extreme FireWire 400, USB 2.0 and eSATA. During the tests show the increase of speed either via USB 3.0, eSATA is clearly the performance king when it comes to external storage devices.
