CompactFlash Association announces new CF5.1 Specification Goals

Some of the key proposed features are:

Key Feature Benefits
Ultra DMA 167 Mode Enables the development of higher performance cards while providing complete backward compatibility.
Sanitize Provides an efficient NAND Block Erase of the entire user data area to return the CF card to “fresh” state before reuse or repurposing. Leverages a command defined in INCITS T13 ACS-2.
Provide Trim Before Write Attribute Protocol Provides an incremental performance increase by optimizing device physical allocation (allows improved internal data organization).
Mandatory Write Caching An enhancement for certain Video Performance Guarantee profiles to improve write performance of CompactFlash cards.
Operating Temperature Range An optional card capability to report the operating temperature range of the card. This allows card/camera combinations to enable use in extreme temperatures.
