The new SDXC announced earlier this year will begin to replace SDHC in 2010. The new memory cards will be able to support speeds as high as 300MB/s and capacities as large as 2TB. The new SDXC readers will also be backwards compatible. This means that SDXC readers will be able to read SDHC, SD, and MMC, so its a win win situation. According to Dailytech, Lenovo, HP, and Dell are actively working on laptops with SDXC support, but no information is available yet from Apple or how soon SDXC will make its way into MacBooks.
