The CompactFlash Association (CFA) has unveiled the latest CF specifications known as CF5.0. The new specs add expansion options and more performance to the CF storage media.
New features of the update include 48-bit addressing, data set management control/Trim, ATA references updated to ATA-6 and ATA-8/ACS-2. Performance control is options, and a change to the interface electrical specification to comply with the ATA standard.
The benefits of these new features include new capacity CF cards beyond the current 137GB limit and data transfers up to 32MB per transfer verses the 128K transfers now. The spec will allow for more efficient clean up of unused space. Other improvements are also added to the new specifications, but the ones mentioned are the most important.
