If you've bought a laptop recently, chances are good it has
an integrated SDHC
memory card reader. Today, the SDHC standard is pretty commonly used in various
devices including digital cameras, camcorders, MP3 players, and many other
devices. By integrating SDHC card readers into laptops, manufacturers have made
the standard even more convenient to use since you don't have to carry an
external reader to download and upload files from a memory card.
Like all other technologies however, SDHC is in the process
of being replaced by a newer, faster standard called SDXC
. The SDXC standard was announced
earlier this year but is not expected to replace SDHC until sometime in 2010.
The new standard is able to support speeds as high as 300MB/s and capacities as
large as 2TB. Thankfully, the SDXC standard is backwards compatible with SDHC,
SD, and MMC memory cards.
As one should expect, laptop manufacturers are jumping on
board with the new format as well. In fact, DailyTech
reporting that Lenovo, HP, and Dell are actively working on laptops
with SDXC support. At this time, no information is available from Apple as to
when the company will jump on board the SDXC bandwagon. The first products that
will use SDXC are expected to be shown at the upcoming 2010 CES trade show in
