Industrial SATA Solid State Flash Disk

Industrial SLC SATA Solid State Flash Disk
Wide Temp

The Wide Temp SATA Solid State Disk is the next generation of storage device based on industrial flash memory technology, which emulates an ordinary magnetic hard disk.

Built for speed, these Solid State Storage Devices need no moving or spinning parts, and that makes no mechanical noise, suitable for used in portable or embedded system, which has only limited power consumption. The Flash Disk Drive products are also free from extra and special algorithm or some firmware driver. Just plug the unit into the SATA slots and operate it as same as a regular Hard Disk Drives.

These high-speed SSD units provide faster and higher performance storage solution for industrial application, embedded computing, high-speed networking, broadband communications, mobile computing, military, medical and aerospace

In Addition of high-performance, the devices are capable of withstanding a higher dree of enivornmental distress, delivering extreme endurance.

Introduction of InnoDisk FiD 2.5 SATA4000

InnoDisk FiD 2.5 SATA4000 products provide high capacity flash memory Solid State Drive (SSD) that
electrically complies with Serial ATA (SATA) standard. InnoDisk FiD 2.5 SATA4000 support SATA I
standard (1.5Hz) with high performance. Sustain read is 37MB(Max) per second, and sustain write is
34MB(Max) per second. InnoDisk FiD 2.5 SATA4000 uses standard 2.5-inch form factor, which can be
used in laptop. InnoDisk FiD 2.5 SATA4000 is also designed for industrial field. The SSD have good
performance, and have small latency time. It effectively reduces the booting time of operation system and
the power consumption is less than hard disk drive (HDD). InnoDisk FiD 2.5 SATA4000 can work in
harsh environment. The SSD is vibration resistance, and can work in lower or higher temperature than HDD.
InnoDisk FiD 2.5 SATA4000 complies with ATA protocol, no additional drives are required, and the SSD
can be configured as a boot device or data storage device.

SATA I Controller

The SATA I bridge controller is 1.5 Gbps (Gen. 1), and support hot-plug. The main function is to bridge
between a legacy IDE storage device and a Serial ATA host. The Serial ATA physical, link and transport layers
are compliant with Serial ATA Gen 1 specification (Gen 1 supports 1.5Gbps data rate). The data burst rate
between SATA I bridge controller and ATA controller is 100MB/sec.

ATA Controller

The ATA controller is equipped with 12KB of internal memory that is used for storing data. The internal memory
can also be used as an intermediate memory for storing data blocks during a wear-leveling procedure. There
are 40KB of internal memory is used for code. A 10KB internal boot ROM includes basic routines for accessing
the flash memories and for loading the main code into the internal memory.

Error Detection and Correction

Highly sophisticated Error Correction Code algorithms are implemented. The ECC unit consists of the Parity
Unit (parity-byte generation) and the Syndrome Unit (syndrome-byte computation). This unit implements an
algorithm that can correct four bits per 512 bytes in an ECC block. Code-byte generation during write
operations, as well as error detection during read operation, is implemented on the fly without any speed


Flash memory can be erased within a limited number of times. This number is called the erase cycle limit or
write endurance limit and is defined by the flash array vendor. The erase cycle limit applies to each individual
erase block in the flash device.
InnoDisk FiD 2.5 SATA4000 uses a wear-leveling algorithm to ensure that consecutive writes of a specific
sector are not written physically to the same page/block in the flash. This spreads flash media usage evenly
across all pages, thereby extending flash lifetime.

Bad Blocks Management

Bad Blocks are blocks that contain one or more invalid bits whose reliability are not guaranteed. The Bad
Blocks may be presented while the SSD is shipped, or may develop during the life time of the SSD. The Bad
Blocks will not exceed more than 3% of the total device volume. When the Bad Blocks is detected, it will be
flagged, and not be used anymore. The SSD implement Bad Blocks management, Bad Blocks replacement,
Error Correct Code to avoid data error occurred. The functions will be enabled automatically to transfer data
from Bad Blocks to spare blocks, and correct error bit.
