Industrial Grade Flash Cards

Industrial Grade Flash Drives (SSD)


Q:  What is Industrial Temperature Grade?

A:  Industrial Temperature Grade is - 40 to + 85º Celcius

Q:  What is Industrial Flash Memory?

A:  Industrial Flash Memory is typically suited for use in high and low temperature extremes, designed to withstand vibration and shock and have a fast read/write time. Typically manufactured with SLC (Single Level Cell) NAND Flash.

Q:  What is Commercial Grade Flash Memory?

A:  Commercial Grade Flash Memory is typically suited for use in moderately high and low temperature extremes, designed to withstand vibration and shock and have a fast read/write time. Typically manufactured with SLC (Single Level Cell) NAND Flash with a temperature rating of 0 to + 70º Celcius.

Q:  What is the warranty for California PC FLASH?

A:  3 to 5 years

Q:  Why purchase California PC FLASH?

A:  3 to 5 year warranty, many cards and drives in stock for immediate shipment, compatibility guaranteed, wide selection of formats, disk modes, transfer modes, capacities, custom configurations, and commercial or industrial temperature grades. Short delivery times for special configurations.

Q:  What is PIO Mode 4?

A:  PIO is short for Programmed Input/Output, a method of transferring data between two devices that uses the computerss main processor as part of the data path. ATA uses PIO and defines the speed of the data transfer in terms of the PIO mode. For example PIO Mode 4 has a Data Transfer Rate of 16.6 MBps. (source webopedia.com)

Q:  What is Ultra DMA?

A: Ultra DMA (sometimes abbreviated as UDMA) was designed with the goal of optimizing the ATA interface as much as possible. The first concept of Ultra DMA consists in using the rising edges as well as the falling edges of the signal for the data transfers, meaning an increase in speed of 100% (with the throughput increasing from 16.6 Mb/s to 33.3 Mb/s). Moreover, Ultra DMA introduces the use of CRC codes for the detection of transmission errors. Thus, the different Ultra DMA modes define the frequency of data transfer. When an error occurs (when the received CRC does not correspond to the data), the transfer occurs in a lower Ultra DMA mode, or even without Ultra DMA. UDMA 4 (Ultra-ATA/66) has a throughput of 66.7 Mb/s. (source kioskea.net)

Q:  What is difference between a Type I and Type II PCMCIA / PC Card?

A: All PC Card devices use an identical 68 pin dual row connecting interface. All are 85.6 mm long and 54.0 mm wide. This is the same size as a credit card. Type I Cards designed to the original specification (version 1.x) are type I and feature a 16-bit interface. They are 3.3 mm thick. Type-II PC Card devices are typically used for memory devices such as RAM, flash memory, OTP, and SRAM cards. Type-II PC Card devices feature a 16- or 32-bit interface. They are 5.0 mm thick. Type-II cards introduced I/O support, allowing devices to attach an array of peripherals or to provide connectors/slots to interfaces for which the host computer had no built-in support. California PC FLASH FPC/FPCI-XXXX Flash Cards are Type II cards. (source: wikipedia.org)

Q:  What types of CompactFlash cards are supported by the California PC FLASH FCFPC-ADPT-02 CF to PC Card/PCMCIA Adapter

A: The California PC FLASH FCFPC-ADPT supports all makes of of Type I and Type II CompactFlash Cards and Micro Drive. You can then use it in a Type II PCMCIA slot (PC Card).

Q:  What is the difference between Removable, Fixed and Auto Detect Disk modes for California PC FLASH CompactFlash and PC Cards

A: Removable disk mode (PCMCIA mode) is designed for cards to be used for hot insertion and removal, such as data collection or to move data from one device to another using a flash memory card. Fixed disk mode (IDE mode) is preferred when the CF or PC Card will be used to host an operating system that will boot up from the flash disk. Under Auto Detect disk mode, the flash disk can auto detct if the host is using PCMCIA or IDE mode.

Q:  What is DMA?

A: Direct memory access (DMA) is a feature of modern computers and microprocessors that allows certain hardware subsystems within the computer to access system memory for reading and/or writing independently of the central processing unit. Many hardware systems use DMA including disk drive controllers, graphics cards, network cards and sound cards. DMA is also used for intra-chip data transfer in multi-core processors, especially in multiprocessor system-on-chips, where its processing element is equipped with a local memory (often called scratchpad memory) and DMA is used for transferring data between the local memory and the main memory. Computers that have DMA channels can transfer data to and from devices with much less CPU overhead than computers without a DMA channel. Similarly a processing element inside a multi-core processor can transfer data to and from its local memory without occupying its processor time and allowing computation and data transfer concurrency.
