In light of the recent security issues with laptops, Seagate has unveiled the Momentus 5400 FDE.2 drive, with native 128-bit AES encryption. The Momentus is a regular SATA drive that encrypts data automatically as it writes. It has a throughput of 1.5gb/sec spinning at 5400 rpm. It also comes with preboot authentication, and a secure erase feature that writes over data many times to allow for reuse. A Seagate spokesman said that the encryption feature increases production costs by about 25%. The drive comes in three flavors, 80GB, 120GB, and 160GB, and relatively cheep, at $130 to $175 for the 80GB model.

ASI computer Technologies Inc., A computer company that serves small to medium sized VAR or integrators who focus on products for government, legal, financial, educational, and health industries, debuted the first laptop to feature the new drive. Kent Tibbils, senior director of platforms, said the ASI NB Model C8015 and C8015+ laptops also began shipping. ASI said it chose it’s 15-inch Centrino Duo Notebook to house the new drive because the laptop already comes with security features such as a biometrics fingerprint reader.

Seagate said it was talking with several large laptop manufacturers, but the drive would be well suited to a varity of platforms including desktops and gaming rigs.

The Only Difference Between Client/Server and P2P is Press Converage

Wednesday, January 10th, 2007

Client/Server networks are composed of many client computer and at least one server. Information saved to the server by a user using a client computer can be accessed by the same user on any other client computer on the network. System Administrators can control the entire network via a centralized location, (the server), making the job of changing settings on files or individual users very easy. This solution is however, very expensive, as the computers used as servers and the I.T. Professionals hired to setup and maintain them, are generally costly.

P2P (peer-to-peer) networks are easier to setup and cheaper to maintain, but generally harder to administrate. They use a hub to connect the peer computers to each other. All you need to create a P2P network are the peer computers and their IP addresses, a hub, and some network cable. Files are shared directly between computers, while each system is separate. Changing permissions is much harder on a P2P though, as an Admin must go to each computer physically to change settings.
