USB 3.0 – SuperSpeed USB3.0

Tuesday, January 17th, 2012

USB 3.0 is the latest revision of the Universal Serial Bus standard released in 2008. Most of your computer peripherals are probably operating via USB 2.0 however super speed USB 3.0 is theoretically up to 10 times faster than its predecessor. It is more than its predecessor’s theoretical maximum bandwidth from 480Mbit/s to 4.8Gbit/s (4,800Mbit/s) as well as increasing maximum power draw from 500mA to 900mA. USB 3.0 cables and devices are also required to achieve the fast transfer speeds in USB 3.0. Majority of 3.0 devices includes external hard drives, hard drive docks flash drives, memory card readers, display adapters, and transfer cables.

Pros  of USB 3.0 –  SuperSpeed USB 3.0 is 10 times faster than USB 2.0. The new SuperSpeed mode has a transfer rate of 4.8Gbps. USB 3.0 can deliver 900mA to the device, compared with USB 2.0′s 500mA. USB 3.0 is compatible with USB 2.0. For that you require a new cable and new host adapter to achieve USB 3.0.  However you can still use the device on a USB 2.0 port and achieve typical USB 2.0 performance. USB 3.0 is also engineered to provide maximum bus power to devices to deliver a better overall user experience. Whether hooking up hard drives, SSDs or memory sticks, USB 3.0 makes a big difference. The other area where USB 3.0 currently makes a difference is high definition webcams, to enable streaming their feeds through to your computer without the compression that was necessary with USB 2.0. SuperSpeed USB 3.0 extension cable will offer a durable, high quality connection that harnesses the full capability of the USB 3.0 standard.

Cons of USB 3.0 – If you use your computer for basic tasks like email, web-browsing, and for other office works, USB 3.0 probably won’t help you much. It won’t affect your standard definition webcam, mouse, keyboard or printer. USB 3.0 cables and hubs are also significantly more expensive. USB 3.0 is also of shorter length than USB 2.0′s five meters and is also limited to a maximum of four ports.

The improvement to SuperSpeed USB 3.0 is for improving the interaction between device and host computer. USB 3.0 equipments in near future would be in more demand. if you’re shopping around for a new system, it’s would be a good idea to look around for a desktop computers with usb 3.0 or usb 3.0 ports in laptops.

Bigger batteries almost always last longer, which is usually a key factor for many traveling by air. Try to find the manufacturer’s listed battery life for the standard battery.

02-Laptops Extended Warranty  - The standard warranty is a limited one and Laptops are more prone to breakdowns due to their portability. Before you buy, look at the warranty for the device. Most computers feature a one-year warranty, but some may offer more, along with extended warranty options.

03-Screen size and resolution - If you intend on doing more than just word processing and web surfing like playing games, watching videos or editing photos on your laptop then don’t forget a decent display. The larger the display, the higher the resolution will typically be, but it also will impact how portable the system is.  However Models with 12-inch displays are much easier to carry through doorways, into tight airline seats, and in coffee shops.

You can adapt, or  you can buy spare laptop keyboards that fit your make and model of laptop computer.

06-Laptop System specifications - A notebook processor is a CPU optimized for notebook computers. The laptop processor is typically a lower-powered processor than those found in similar desktop machines, although some laptop makers have used desktop processors in their laptops to get a performance edge. Mobile processors typically were slower than desktop CPUs but that has changed. Dual-core processors are common and help with multitasking. The type of processors found in the laptop will vary based upon the size and purpose of the laptop. If you require a high-productive laptop choose among models equipped with Windows 7 or Mac OS X supported with 1 GHz processor (or faster) and at least 1 GB RAM. When considering what to look for in a laptop make sure that your new notebook’s specifications of operating system and technical parameters fits your needs in programs.
