Serial ATA vs. Parallel IDE

Filed under
Hardware

Over the past few years SATA has become a standard interface on hard drives and is starting to show up in many peripheral devices. We're taking a look at the performance difference between similar hard drives running on the two interfaces through a range of Linux benchmarks on (where applicable) ReiserFS v3 partitions.

Both parallel and serial ATA support were provided by on-board VIA chipsets.

Linux Kernel 2.6.12.4 was our test kernel running on Mandriva's 2005LE operating system. At the time of testing it was the latest stable release of the 2.6 stable kernel tree.

"libata" is currently a work in progress. Kernel 2.6.13 will include an updated release marked as enterprise ready. SATA drivers currently have simple error handling and features such as hotplug support are being worked on.

Our test suite is comprised of bonnie++, dd, zcav, and DiskWriggler. These should provide a range of direct to hardware i/o statistics and some "real world" FS read/write figures.

Top 4 CDN services for hosting open source libraries

A CDN, or content delivery network, is a network of strategically placed servers located around the world used for the purpose of delivering files faster to users. A traditional CDN will allow you to accelerate your website's images, CSS files, JS files, and any other piece of static content. This allows website owners to accelerate all of their own content as well as provide them with additional features and configuration options. These premium services typically require payment based on the amount of bandwidth a project uses. Read more

Bash Bunny: Big hacks come in tiny packages

  • Top 4 CDN services for hosting open source libraries
    A CDN, or content delivery network, is a network of strategically placed servers located around the world used for the purpose of delivering files faster to users. A traditional CDN will allow you to accelerate your website's images, CSS files, JS files, and any other piece of static content. This allows website owners to accelerate all of their own content as well as provide them with additional features and configuration options. These premium services typically require payment based on the amount of bandwidth a project uses. However, if your project doesn't justify the cost of implementing a traditional CDN, the use of an open source CDN may be more suitable. Typically, these types of CDNs allow you to link to popular web-based libraries (CSS/JS frameworks, for example), which are then delivered to your web visitors from the free CDN's servers. Although CDN services for open source libraries do not allow you to upload your own content to their servers, they can help you accelerate libraries globally and improve your website's redundancy.
  • Users stand up, speak out, and deliver data on OpenStack growth
    Last week, the OpenStack Foundation announced the results of its ninth user survey. OpenStack users responded in record-breaking numbers to participate, and their voices as revealed in the data tell the real story of OpenStack. The OpenStack community is growing, thriving with new users, deployments, code contributions, and collaborations, all on the rise. User diversity is expanding across geographies and organizational sizes. And OpenStack's ability to integrate with innovative technologies is paving the way for advancements not even dreamed of just five years ago.
