Migrating Data

Getting Data From Here To There

The need for effective data migration methods is becoming more popular due the increase in file storage. As hard drives and file sizes become larger, data migration through the use of optical media such as CDs and DVDs is no longer a viable solution. Data migration is a common practice when computers systems reach the end of their life span or desired performance expectations and data from the older system needs to be migrated to a new system. Home users experience the need for data migration after purchasing a new computer or when upgrading operating systems. IT professionals frequently experience the need to move data from one system to another when facilitating system upgrades.

The greatest challenge faced when moving data is the amount of time consumed by transferring information due to bandwidth limitations. The most common method for transferring information is through an Ethernet network. When moving large amounts of data through a network connection, a tremendous amount of time is usually required due to low bandwidth and high network traffic. The delay caused from high congestion can limit productivity and reduce the number of upgraded systems that can be turned around in a given time frame.

For home users a network method can seem complex and intimidating. Before migrating data through an Ethernet network, configuration changes must be made to file permissions, firewall exemptions, workgroups, IP addresses and subnet masks. The absence or complexity of a network for data migration in a home user application stresses the need for a cost effective and simple alternative.

One solution for both IT professionals and home users is to establish a peer-to-peer connection that is not dependent upon Ethernet networking. A peer-to-peer connection can be established using a unique USB data transfer cable. Because the connection is established over USB, Ethernet network congestion will not interfere with the data transfer rate. USB transfer cables also do not require complex configurations required by Ethernet networking. Instead, a convenient visual software program allows users to drop and drag selected files between both computers. The high speed transfer rate of USB exceeds most Ethernet networks by over four times, reducing the overall time spent on transferring gigabytes or terabytes of information.

Data migration is also used to recover data from a computer that is no longer operational. When this occurs, data migration through network connectivity is not possible. As long as the hard drive is not the reason for the inoperable condition of the computer, two types of USB solutions exist to remove the information. Both solutions will require removal of the hard drive from the computer.

The first solution is a USB to IDE or Sata adapter that can be connected to the hard drive and then to a functional computer. The hard drive from the inoperable computer will appear as a new drive on the functional computer. The user can then access the drive and transfer files by using a dropping and dragging method.

The second solution is a USB hard drive enclosure that is used to encase the hard drive from the inoperable computer, converting it to an external hard drive device. Files are transferred in the same way as the USB to IDE or Sata solution. A byproduct of this method is the formation of a portable media solution. After all necessary data has been transferred, the external hard drive can be erased and then serve as a portable drive to transport video files, music, documents or programs between computer systems. This can be very useful to IT professionals as an alternative data migration solution. Files from one computer can be transferred to the external drive and then transferred to a different system. This method will take longer than using a USB transfer cable solution since the transfer is not simultaneous; however this method may be preferred when two computer systems are not in close proximity of each other.
