Frequently Asked Questions:
SDXC Memory Card
Q. What is SDXC?
A. The next generation of SD memory card, the
SDXC (Secure Digital Extended Capacity) format
provides larger storage capacities and ultra fast
data transfer rates. It is based on the Secure Digital
Association (SDA) Card Specification 3.01. The new
storage capacities range from more than 32GB to 2TB.
The new Ultra High Speed (UHS) architecture allows
for enhanced transfer rates designed to reach speeds
up to a maximum transfer rate of 104MB/s today and
300MB/s in the future.
Q. Is SDXC backwards compatible?
A.
Cards: SDXC memory cards can be used only with
SDXC host products.
Host Devices: SDXC host products can use SD, SDHC
and SDXC memory cards. SDHC memory cards can be
used with SDHC and SDXC host products. SDHC host
products can use both SD and SDHC memory cards.

Q. What product is Kingston introducing that
uses this new specification?
A. Kingston® is shipping a 64GB SDXC UHS 1 Class 10
memory card. The part number is SD10A/64GB and can
be decoded as follows: SD = SDXC specification 3.01
designed form factor, 9 pin out, 10 = minimum data
transfer rate, A = UHS1 bus, operation mode SDR104,
64GB = card capacity. The card label follows the new
SDA guidelines for this new specification including the
new U1 speed class marking.
Q. What is the significance of the new I and U1
class mark?
A. It indicates the performance class of the new ultra
high-speed bus architecture of the SDXC card. The UHS
I card type supports various modes of operation and
signal timing. Kingston’s SDXC UHS I product uses the
UHS104 mode of operation. The I and U1 markings are
mandatory on all packaging and manuals but optional
on the memory card label. The I and U1 markings
can also be found on the host device packaging and
manuals for consumers to ensure SDXC compatibility
between the memory card and host device.

Q. Is there a difference between standard class
speed rating and universal high-speed rating?
A. Yes, though both are an indicator of the unit of
speed of the card. The markings appear on the card and
host devices. The host device actually queries the SDXC
card controller to perform the proper speed operation.
There are two design parameters for the rate of data
transfer — a minimum and maximum speed. Class
speed is defined as the minimum write transfer speed.
The SDXC UHS-1 speed is defined as the maximum
speed (104MB/s) for which the card has been designed.
The following chart shows the realized speed
parameters of Kingston’s new SDXC card:
SD10A/64GB Class
Minimum 10MB/s write Class 10
Maximum Up to 65MB/s read
Up to 30MB/s write
UHS104
In summary, consumers will need to match these
two speed ratings with the host device to ensure
compatibility and optimum speed.
Q. Describe the speed specifications of Kingston’s
SDXC product and how they compare to other SDXC
products currently available in the market.
A. Kingston’s SD10A/64GB product is a UHS104 card
type based on the latest SD specification 3.01. It is
designed to meet the performance specifications of the
Ultra High Speed Bus I, single data rate 104 operating
mode. The architecture of a UHS104 card reaches a
maximum throughput of 104MB/s read/write transfer
rates. Today, the actual performance of Kingston’s SDXC
UHS 1 card realizes a minimum data transfer rate of
10MB/s (Class 10) and a maximum transfer rate of up
to 60MB/s read and up to 35MB/s write. Few memory
card manufacturers currently offer SDXC products
and if they do have a product, the bus mode is not on
their packaging or product and may not support the
performance inherent in new UHS architecture.
Q. Will SDXC cards work with SDHC host devices?
A. SDXC cards use the same physical format and
pin out as SD or SDHC cards, but can only be used
with SDXC host products such as digital cameras or
camcorders. They are not backwards compatible
with SDHC or standard SD hosts. Consumers should
verify that the host product is SDXC compatible by
locating an SDXC logo on the host product,
packaging, instruction manual or other manufacturer’s
information. Not all card readers are SDXC compatible.
Kingston’s USB 3.0 Media Reader (part number (FCR-
HS3) is compatible with SDXC cards. The USB 3.0 Media
Reader works if the connected PC uses an operating
system that supports exFAT.
Q. What PC operating systems support SDXC?
A. SDXC cards use the exFAT file system for
organizing stored data. Therefore, when transferring
files from card to PCs the following operating systems
are compatible with SDXC cards: Microsoft Windows®
7, Windows Vista® (SP1 or later) and Windows XP (SP2
or later with exFAT update). SDXC compatible drivers
for the SD slot can be downloaded from the Microsoft
Download Center website.
Q. What are typical applications for use of the
SDXC card?
A. High-definition video, high-resolution, or RAW
still photos captured by prosumers and broadcasters
that have advanced digital cameras and camcorders
that need ultra-fast continuous shooting speed and
the additional bandwidth needed will be among the
first to benefit from the amplified performance of the
SDXC form factor. Other consumer electronic devices
that will benefit from a performance category of SD
cards in the future include HDTVs, Blu-ray players,
navigation devices, computers, card readers and
mobile phones.

Q. How many videos/photos can be stored on a
64GB SDXC card?
A. The minutes of video and number of photos that
can be stored varies based upon camera models and
internal file size and settings, as well as user-selected
resolution and frame rates. For example, using the
Canon Vixia HF M30 model with settings of MXP
24MBps, 60i frame rate, nearly 6 hours of recorded
video can be stored. Using movie mode on the Canon
A3100 IS, 8 hours of video recording can be stored and
in photo program mode (12 Megapixels, avg. of 2.72 MB
file size), nearly 22,000 pictures can be captured.
Q. Can I use my existing card reader with my
SDXC memory card?
A. Some card reader designs may not support the new
SDXC card format. Check with the reader manufacturer
to see if it is compatible with the SDXC form factor. Even
if the SD slot accepts the SDXC card, the PC must utilize
an exFAT file system for proper SDXC card operation.
Check with the PC manufacturer if SDXC drivers are
also needed. Kingston’s USB 3.0 Media Reader (part
number (FCR-HS3) is compatible with SDXC cards. The
USB 3.0 Media Reader works if the connected PC uses
an operating system that supports exFAT.
Q. Can an SDXC card be reformatted?
A. Yes, but only with an SDXC host that supports
exFAT file system. If the host does not support exFAT
formatting then a message may appear to format the
card or it may not recognize the card and will not allow
a reformat. In the event that a message appears to
format the card, doing so will erase all the data on the
SDXC memory card and format the card for a different
file system that will not longer work with SDXC host
products. An additional utility, SD Formatter 3.0 (beta
version), is available for formatting an SDXC card at
www.sdcard.org.
