Transcend releases successor to Compact Flash, CFast

updated 06:05 am EDT, Wed November 3, 2010

Boosts throughput from 90MB/sec to 375MB/sec

Transcend has released successor to the Compact Flash format the CFast, that remains favored for use in high-end digital cameras. The new format significantly boosts data throughput from 90MB/sec in to 375MB/sec by integrating a SATA interface into the existing CF form factor. For professional photographers, the higher transfer speed could mean shooting photos that require multiple shot sequences to taken without creating the potential for a memory buffer overload.

While the new cards come in consumer friendly capacities of 2GB, 4GB, 8GB and 16GB, the current range is aimed a industrial applications. Also, as might be expected, the move from the IDE interface to the SATA interface means that although the new flash cards have the same form factor as current, they are not backwards compatible.

The next generation of consumer compact flash cards will feature the CF5.0 specification which uses 48 bit addressing to boost the current limitation of 137GB up to a massive 144PB.

    The article is unclear

    Is CFAST an implementation of some industry standard, like CF5.0? If it's not who cares about it. If it is why doesn't the article say so?

    CFast is an industry standard, being an implementation of Compact Flash using an SATA bus. So, um, yes, it is a standard (the name is also trademarked to the CFA, so it's part of their thing).

    CFS 5.0 is a specification of the card's working capabilities, while CFast just indicates it is an SATA bus.

    If it's not who cares about it. If it is why doesn't the article say so?

    Um, anyone who cares about speed would care, regardless if it is a 'standard'. Companies use 'non-standard' parts all the time for the sake of 'speed' or 'power savings' or some reason.

    But it isn't a worry, since it is based on a standard. The article doesn't say so, because those who actually care (rather than those who just want to bash products) would already know what CFast is.

    Bear in mind that CFast cards use a different controller (SATA vs. ATA) and, as such, will not work in most current devices.
