Overview: This Sony SD memory card is the world's toughest
and fastest SD card, designed for professional photographers that shoot in
extreme conditions. The SF-G series SDHC/SDXC cards have new design features
that meet Sony's TOUGH specification for durability and reliability. This card
has a memory capacity of 64 GB, and comes in a clear plastic case.
Capacity: Because some of the memory space is occupied by
system management data, the actual usable memory space is slightly less than the
total capacity of the card. For this card, approximately 57.6 GB is available.
TOUGH Specification: The SF-G series SD memory cards have
the following TOUGH design features:
- Bend Strength: Conventional SD cards are constructed in 3 pieces. The
TOUGH card features monolithic (1-piece) construction with high hardness
materials, giving it the highest level of bend strength (180N of force), which
is 18 times greater than the SD standard (10N). This eliminates the risk of
physical damage and protects the data recorded onto the card.
- Ribless Design/No Write Protection Switch: New specifications from the
SD Association allows the removal of easy-to-break parts, such as the front ribs
and the side-mounted data protection switch.
- Waterproof and Dustproof: The monolithic structure is completely
sealed, giving the card higher IEC waterproof and dustproof ratings. The TOUGH
card can be submerged in 5 meters of water for up to 72 hours (IPX8). Even if
you drop the card in mud, you can wash it off in fresh water, wipe it off, and
use it again. The card has the highest dustproof rating (IP6X), meaning it keeps
all dust out of the interior.
- Shock Resistance: The TOUGH card is made of solid materials
that protect the internal components from damage when dropped from a height of 5
meters (16.4 feet).
- High Reliability: In addition, the SF-G series cards can
withstand many other hazards including temperature extremes (-13°
to 185°), UV rays, X-rays, magnetic fields (2500 gauss for 70 hours), and static electricity
(up to +/- 15kV air discharge).
UHS-II Interface: The card has a UHS-II interface which
enables high-speed data transfer for SDHC and SDXC cards. The card features very
high read and write speeds, that allow you to capture a series of
high-resolution photos as well as 4K video. It also has a faster buffer clearing
time, letting you shoot multi-frame bursts of up to 20 frames per second. The
SF-G series cards have the world's fastest write speed of up to 299 MB/s, and a
read speed of up to 300 MB/s. The memory card supports the following speed class
standards: Class 10 (SD Speed Class), Class 3 (UHS Speed Class), and V90 (Video
Downloadable Software: The card includes a link to
downloadable File Rescue software (Windows only), which can recover photos and videos that have
been accidentally damaged or deleted on the card. You can also download SD Scan
Utility (for Windows and Mac), which regularly and automatically scans your SD
memory card and let you know when it's wearing out and time to replace it.
