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 »
