SanDisk Industrial Grade CompactFlash 5000
These capabilities include:
1.7.1
The 512-byte sector size of the CompactFlash 5000 is the same as that of an
IDE magnetic disk drive. To write or read a sector (or multiple sectors), the
host computer software simply issues a Read or Write command to the card.
This command contains the address and the number of sectors to write/read.
The host software then waits for the command to be completed.
The host software does not participate in the details of how the flash memory
is erased, programmed or read. This is extremely important as flash devices
are expected to get more and more complex in the future. Because the
CompactFlash 5000 uses an intelligent on-board controller, the host system
software will not need to be changed as new flash memory evolves.
In other words, systems that support CompactFlash 5000 now will be able to
access future SanDisk cards built with new flash technology without any need
to update or change host software.
1.7.2
CompactFlash 5000 contains a sophisticated defect and error management
system.
This system is similar to the systems found on magnetic disk drives, and in
many cases offers enhancements.
If necessary, the card will rewrite data from a defective sector to a good
sector. This is completely transparent to the host and does not consume any
user data space.
The CompactFlash 5000 soft error rate specification is much better than the
magnetic disk drive specification.
In the extremely rare case that a read error does occur, CompactFlash 5000
has innovative algorithms to recover the data by using hardware on-the-fly 8
bit Error Detection Code/Error Correction Code (EDC/ECC), based on a BCH
algorithm.
These defect and error management systems, coupled with the solid state
construction, give SanDisk CompactFlash 5000 unparalleled reliability.
