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.
