  }}</ref> Prior to 2006, CF drives using magnetic media offered the highest capacities (up to 8 [[gigabyte|GiB]]<!--2^24×512-->). Now there are solid-state cards with higher capacities (up to 512&nbsp;GB).<ref>{{Cite web |url=http://www.lexar.com/products/lexar-professional-800x-compactflash-cf-card |title=Lexar® Professional 800x CompactFlash® card &#124; Lexar |access-date=2015-11-25 |archive-url=https://web.archive.org/web/20151126060038/http://www.lexar.com/products/lexar-professional-800x-compactflash-cf-card |archive-date=2015-11-26 |url-status=dead }}</ref>

As of 2011, [[solid-state drives]] (SSDs) have supplanted both kinds of CF drive for large capacity requirements.

In early 2008, the CFA demonstrated CompactFlash cards with a built in [[SATA]] interface.<ref>{{cite web|url=https://www.engadget.com/2007/11/17/submerged-camera-holds-functional-memory-card-two-years-after-ac/|title=Submerged camera holds functional memory card two years after accident|website=engadget.com|date=17 November 2007 |access-date=18 March 2018}}</ref> Several companies make adapters that allow CF cards to be connected to [[Peripheral Component Interconnect|PCI]], [[PCMCIA]], [[Parallel ATA|IDE]] and [[SATA]] connections,<ref>{{cite web|url=http://www.addonics.com/products/cf_adapter/|title=Compact Flash and Secure Digital Adapters|publisher=Addonics|access-date=2008-05-18|archive-url=https://web.archive.org/web/20080509161613/http://www.addonics.com/products/cf_adapter/|archive-date=2008-05-09|url-status=dead}}</ref> allowing a CF card to act as a [[solid-state drive]] with virtually any operating system or BIOS, and even in a [[RAID]] configuration.

CF cards may perform the function of the master or slave drive on the IDE bus, but have issues sharing the bus. Moreover, late-model cards that provide [[Direct memory access|DMA]] (using UDMA or MWDMA) may present problems when used through a passive adapter that does not support DMA.<ref>{{cite web|url=http://www.fccps.cz/download/adv/frr/cf.html|title=CompactFlash cards and DMA/UDMA support in True IDE (tm) mode|website=www.fccps.cz|access-date=18 March 2018}}</ref>
