Because SATA II is nearly four times faster than Firewire and over six times faster than USB, it is the ideal interface for audio and video editing applications, high-end graphics, and all your other capacity hungry applications that demand continuous high performance throughput. A7. When an external drive without RAID fails, all data is lost. Without RAID a failed drive can mean the loss of hours of irreplaceable creative output.

Serial ATA is the latest standard in IDE(Atapi) devices. The maximum speed of Serial ATA is 150MB/s (the maximum speed of Parallel ATA is 133MB/s, the ATA133 standard). The cable for serial ATA has a minimum of 4 wires (extra ground wires can be applied), a 7-pin connectro and a maximum length of 1metre (about 3.1 feet). Because of the serial protocol only 1 device can be connected to each cable.

USB 2.0 supports a speed of 480 Mbit/s and FireWire 400 supports a speed of 400 Mbit/s. This would seem to indicate that USB is faster than FireWire, right? Actually, the opposite is often true. Differences in the architecture of the two interfaces affect the actual sustained throughput (reading and writing files). FireWire uses a "Peer-to-Peer" architecture that is intelligent and negotiates bus conflicts to determine the sustained data transfer speed. USB 2.

USB 2.0 offers high-speed 40X performance over fast speed USB 1.1 based systems. USB 2.0 is designed for supporting devices with high I/O requirements such as scanners, storage, cameras, and LAN devices. USB 2.0 is backwards compatible with USB 1.1 so that you can continue to use devices, such as USB keyboards and mice, which do not require the high bandwidth that USB 2.0 offers. When purchasing USB 2.0 devices look for the High Speed USB logo. This ensures that the device meets the USB 2.

The 40X speed improvement is specific to the bus. What this literally means, is that the bus is no longer the bottleneck in performance. The actual performance improvement for a given product is dependent on how fast that product can run. Over time, you should see product vendors improving their products to take advantage of the 40X bus.

A standard 9 pin serial port on a computer has a maximum speed of 115Kbps(115,200 bits per second). USB easily beats that with a maximum speed of 12Mbps (12,000,000 bits per sec) and USB 2.0 with 480Mbps (480,000,000). Back To Questions

A3: SAS will be used in the same environments in which SCSI and Fibre Channel are employed today. SAS is designed to be used in high availability, enterprise environments where maximum random performance is required. SATA on the other hand is optimized for sequential I/O operations where the requirement is to transfer large sequential blocks of data to and from a drive.

If you are installing Windows XP on a system where you only have Serial ATA Drives you might encounter a problem where Windows does not seem to detect your Hard Drive and reports "No mass storage device found" during an installation (this occurs in Windows NT and Windows 2000 as well). This is because there are no SATA HD drivers in Windows XP/2K/NT and you need to load 3rd party drivers (just like with many SCSI drives).

Yes, however, some other manufacturers' drivers may incorrectly assume a PCI-X Sonnet card is another SATA card; kernel panics may occur; the PCIe cards are not suspect to this problem.

These logos are part of USB Promoter Group's branding program that ensures the quality of USB products. The USB 2.0 certified products would display a blue, white and red logo, bearing the words Certified and Hi-Speed. The classic USB 1.1 certified products would display a black and white logo with the words USB and Certified. Under a license from USB-IF, products must pass the compliance tests before manufacturers can use one of the two trademarked logos.

Anyone experienced with both USB and 1394 (FireWire) probably considers the latter a complement to USB, rather than a replacement. It offers much higher speeds and synchronous and asynchronous video / audio / data transfer. USB is easy to use and works well for computer peripherals requiring less speed, such as keyboards and trackballs. FireWire) is just as easy to use but works at a much higher speed, ideal for mass storage and dozens of other applications.

Very doubtfully. The total link speed is still bound by the slowest link in the chain. That link is almost certainly the physical interface on your Magellan and not the serial port on your computer. Even if you have a super-spiffy USB 2.0 serial adapter that's talking at 480Mbits/second to the host, the speed is still limited by the max speed of the serial interface (a max of 115.2Kbits/sec) when talking to your unit.

A6. The initial, primary benefit of Serial ATA will be the simplicity of system design due to the new cables. As storage solutions based on Serial ATA drives and controllers arrive in the market, end users will benefit from the lower price of ATA RAID solutions. A7. You get the same performance advantages on both our 7506 Series parallel RAID controllers and 8506 series Serial ATA controllers.

There is a difference in Hi-Speed USB and USB 2.0. The difference is that the USB 2.0 specification covers all three speeds 480 Mbps, 12 Mbps, and 1.5 Mbps. "Hi-Speed USB" refers to just the 480 Mbps portion of the USB 2.0 specification. We now use the term "USB" to refer to the 12Mbps and 1.5Mbps speeds.

The best answer to this is a firm "maybe". DOS device drivers are available for most USB and Firewire controllers. If such drivers are added to a DOS boot diskette so that your USB or Firewire drive is "seen" by DOS, SpinRite will also be able to "see" and operate with it. However, the performance of the drive through the DOS drivers and the serial (USB/Firewire) cable will likely be far lower than if the external drive were connected directly to a PC's motherboard controller.

Serial ATA is a disk-interface technology developed by a group of the industry's leading vendors to replace parallel ATA. The group known as the Serial ATA International Organization (SATA-IO) owns the development of the Serial ATA technology and maintenance of its specifications. Scalability - Serial ATA is a point-to-point connection and allows multiple ports to be aggregated into a single controller that is typically located either on the motherboard or as an add-in, RAID card.

Serial ATA, the successor to parallel ATA for data storage, is a point-to-point connection that delivers full throughput to each storage device by allowing a single controller to manage multiple ports. Serial ATA technology starts at transfer rates of 1.5 Gbit/sec with a roadmap up to 3.0 Gbit/sec and ultimately up to 6.0 Gbit/sec. Serial ATA cables are thinner, simpler to route and install, and provide better airflow for system cooling than parallel ATA cables.

Business Portable Internet from Rogers is up to 50 times the speed of dial-up. It's a high-speed Internet service with the innovative feature of service portability.

Hi-Speed Browser will not change the speed of any downloads you get over the internet. You will still download movies, games, sound files and programs at the same speed as before. The Hi-Speed Browser will greatly decrease the amount of time it takes to load the webpages.

The simplest way is to look for a Certified Hi-Speed USB logo on the retail packaging or on the product itself. The logo is exactly as shown on the right; it tells you what you are plugging into your USB port has passed the Hi-Speed compliance tests, meaning the product can enter Hi-speed USB mode if your system supports it. USBInfo & SiSoftware Sandra can also report USB speed status.

If you have not found what you are after here, the USB-IF web site is the definitive source for all information pertaining to USB 2.0.

Assuming you have a PC that has USB 1.1 (which is most likely), if you plug your Hi-Speed USB 2.0 peripheral into the USB 1.1 system, your system will perform at the USB 1.1 speed. If you would like to use High-speed USB 2.0, you will need to update your PC either by adding in a PCI add-in card or purchasing a new MB with a discrete host controller that supports Hi-Speed USB 2.0 and installing Hi-Speed USB 2.0 drivers.

Refer to the Quatech COM CD from which you installed your unit, or the installation files you downloaded to your hard-drive and used to install your USB serial port. Look for the history.txt file. Open this file and you will see the revision history for that driver. The most recent information will be at the top of the file.

A6. The 3ware 9550SX fully complies with the SATA 2.5 specification. For information on the specification, please visit the Serial-IO Organization's site at www.sata-io.org
