However, Delkin CardBus adapters and all CardBus products worldwide have a set of gold dimples or "buttons" across the top of the leading edge, which inserts into the laptop. These buttons serve a keying function and prevent the insertion of the adapter into non-CardBus compatible laptops. CardBus slots are common on all modern laptops from manufacturers like Dell, Toshiba, Sony and many others. The CardBus 32 adapter inserts completely within its host without any external cabling and operates at a power-saving 3.3 volts, extending battery life in most configurations.|
The CardBus standard, while not well known to the general computing population, has been in place since 1997, and supported by virtually all notebook vendors since 1998. CardBus is standard on virtually all modern Windows and Mac OS systems. CardBus provides higher levels of performance than the 16-bit PC Card standard, and is able to take advantage of internal bus speeds that can be four to six times faster. Tests on Delkin eFilm PRO cards and other high-speed CF cards revealed similar speed increases of four to six times that of standard 16-bit CF adapters. 100 Megabytes of JPEG photos on a Delkin PRO card were transferred to a Dell laptop with both a Delkin 16-bit adapter and the new CardBus 32 adapter. The CardBus adapter took 18 seconds (5.5MB/s) to transfer the images and the standard adapter took more than four times as long, taking one minute, 26 seconds (1.16MB/s) to transfer.
The Delkin CardBus 32 adapter has a theoretical maximum speed of 132MB/s. Speed in real world applications is determined by the speed of the CPU and flash chips within the CF card. High-speed cards will operate much faster than other cards not designed to be high speed. Delkin CardBus 32 adapters also utilize a patented chip, which reduces the burden on the host CPU to 10% or less, further increasing the value of this product. The Delkin CardBus 32 adapter is currently shipping with a retail price of $59.99.
