What is a CFast SSD?
To attain the higher performance, CFast cards have a SATA interface versus the ATA interface of the CompactFlash cards. CFast cards are electrically compliant with SATA-IO specifications, but physically use a different connector and shape defined by the CFA.
A CFast flash card is based on solid state NAND memory and has the same length and width as the Compact Flash card. It is however 0.3mm thicker than the CompactFlash type I cards which are the majority of CF in the market.
CFast dimensions are as follows:
- Length 36.4mm
- Width 42.8mm
- Thickness 3.6mm
Cactus offers two varieties of CFast cards. An Industrial Grade based on SLC NAND and a Commercial Grade based on MLC NAND.
