for your reference.
Our CFs
General CF
(example)
Anxiety on using general CFs
Operating
temperature -40 to 85 °C 0 to 60 °C - They do not meet thermal specification of PC.
- Their thermal margin is so small that data can be broken easily.
Flash memory type SLC MLC - Data can be broken easily.
- Write/Erase endurance is bad as below.
Write/Erase
endurance 100,000 times 3,000 times - Product life against write/erase cycles should be short.
- Data retention becomes weak after write/erase aging.
Ware leveling Static Dynamic - Specific part of cells may be writed / erased frequently so that
life troubles can happen early.
Fixed Disk YES NO - CF has the bit which indicates “Fixed Disk”. Windows treats the
CF as local disk if this bit is active, or treats as removable disk.
If Windows is installed to removable disk, the operation can
not be guaranteed.
Combinatorial
evaluation YES NO - CF is connected as IDE so that compatibility problem between
master and slave may happen. We did not evaluate this
problem for general CFs. Therefore some problems may happen
(for example, PC may be unable to recognize the CF).
Various evaluation YES NO - All our evaluation tests are done with our CFs. So we can not
guarantee the operation of PC with any other CFs.
If you need to use our PC under its specification, you have to use our CFs. If you use any other CFs,
CONTEC cannot guarantee this PC’s specification.
