Kingston 8gb ultimate compact flash memory card, model: cf/8gb-u. Ds-dh
This high-speed digital film helps your camera capture images faster, so you spend more time taking pictures and less time waiting on your camera. Professionals know that a single image can be more valuable than all their equipment combined. To risk losing an award-winning image because of a hard disk failure or breakdown is unacceptable. Features: solid state: flash storage devices, as semiconductor storage devices, have no moving parts and thereby are not subject to the mechanical failure issues of hard drives. Their overall data reliability enabled them to dominate the convenienceoriented portable memory products market, operating silently with a zero decibel noise level. Small physical size (or form factor): flash storage devices are designed to be easily transported. Convenience is an important criterion, especially for consumer and corporate applications. High data reliability: flash memory is very reliable and many of the flash storage device types also include error correction code (ecc) checking to detect singlebit errors. For example, kingston s compactflash ā cards have a rated error specification of less than one (1) bit in 1,000,000,000,000,000 bits read (1 bit per 10 bits read). Kingston flash data retention: kingston flash storage devices are rated for up to 10 years under normal use. Important information should also be backed up on other media for long-term safekeeping. Wear-leveling technology: kingston flash storage devices (excluding smartmedia cards) incorporate controllers utilizing advanced wear-leveling technology, which distributes write cycles across the flash card. Wear-leveling thus extends the useful life of a flash memory card (for details, please see kingston flash cell endurance section, next). Flash cell endurance: up to 10,000 multi- level cell (mlc) flash or up to 100,000 single-level cell (slc flash) write cycles per physical sector. According to toshiba, the inventor of flash memory: the 10,000 cycles of mlc nand is more than sufficient for a wide range of consumer applications, from storing documents to digital photos. For example, if a 256mb mlc nand flashbased card can typically store 250 pictures from a 4-megapixel camera (a conservative estimate), its 10,000 write/erase cycles, combined with wear-leveling algorithms in the controller, will enable the user to store and/or view approximately 2.5 Million pictures within the expected useful life of the card. 1 For usb flash drives, toshiba calculated that a 10,000 write cycle endurance would enable customers to completely write and erase the entire contents once per day for 27 years, well beyond the life of the hardware. Slc flash based-products, typically found in kingston s elite pro cards and datatraveler 2.0 Usb flash drives, offer both high-performance and highendurance. Automatic bad sector remapping: kingston flash controllers automatically lock out sections with bad memory cells (bad blocksā) and move the data to other sections (spare blocksā) to avoid data corruption. During factory formatting (as described in section 2), spare blocks are set aside on the flash storage device for remapping bad sectors over time. High-quality connectors: kingston s flash storage devices have connectors rated for more than 10,000 insertions. Operating temperature and humidity: 0ā° c 60ā° c, 5% 95% humidity high-capacity: flash storage devices can provide large storage capacities in a very small form factor. This flexibility makes them ideal for consumer uses, such as digital film or storage for mp3 music, where portability and convenience are important. High-performance: kingston s elite pro and hi-speed datatraveler usb flash drives are faster than many standard flash products and many competitive products. Kingston s engineers test and select high-performance controllers to ensure that kingston s flash cards are among the performance leaders. Please see the appendix for information about usb and hi-speed usb performance. Kingston standard flash products offer moderate performance levels for general purpose applications. Low power consumption: unlike standard dram memory that needs to be constantly powered on to maintain its data, flash memory is non-volatile and does not require power to maintain its data. Flash memorys low power consumption results in longer battery life for the host device. Plug and play support: kingston s flash memory line supports plug and play. With plug and play technology and compatible computer operating systems, a flash storage device can be inserted into a computer or a flash media reader and be quickly recognized and accessed by the computer. Hot-swapping support: hot-swapping allows for plugging or unplugging flash storage devices into a compatible computer or reader without needing to power off and restart the computer. This feature enhances the portability and convenience of flash storage devices for transferring data, pictures or music between two computers or devices. System performance: minimum sustained write speed: 100x (15 mb/sec), minimum sustained read speed: 100x (23 mb/sec), physical specifications: length 1.433 In. (36.40Mm) - type i, width 1.685 In. (42.80Mm) - type i, height 0.130 In. (3.30Mm) - type i, 11.4 G max - type i power required: voltage 3.3V 5% or 5v ā± 10%, high performance read current 34ma at 5v; 21 ma at 3.3V rms, high performance write current 34ma at 5v; 21 ma at 3.3V rms certifications: fcc part 15, vcci, ce.
