More PCI-express SSD cards coming to OS X

SSD technology as a replacement for conventional hard drives has been one of the biggest advancements in modern computing, allowing for massive speed improvements along with far less power usage.

Solid-state technology has been around for years in the form of flash drives and MP3 players, but only in the past 3 to 4 years has the technology taken off, allowing for larger storage devices to be developed.

While most people envision an SSD drive to be in the form factor of a 2.5-inch notebook drive, the technology is also available in a PCI-express card format that allows for … Read more

Thunderbolt gearing up to stick around

Apple's last major connectivity advancement was in the late '90s with FireWire, which was used as a replacement for the SCSI bus on Mac systems; however, the licensing and complexity of the port made it a less attractive option than alternatives like USB for many device manufacturers, especially given the ease of implementation and eventual speed of USB 2.0. While FireWire has extended beyond its initial 400Mbps speeds to offer 800Mbps, and potentially up to 3,200Mbps, in the face of current alternatives the technology does not seem to be advancing much beyond its current implementations.

Tilera's balancing act: 100 cores vs. market realities

While we're all familiar with the steady increase in the number of cores in mainstream PC and server processors, the corresponding progress in the embedded-processor market has been anything but steady.

With mainstream PC microprocessors standardizing on four-core designs such as Intel's Core i7 and leading-edge server chips ranging from 8 to 16 cores, single-core chips are no longer competitive. For embedded systems, however, one core may still be the right answer; if more are needed, the choices range up into the hundreds.

The latest announcement in the many-core embedded processor market is Tilera's Tile-Gx family, which … Read more
