Memory specialist SanDisk
has created an SD card
with 512 gigabytes
(512GB) of storage space -
the highest capacity ever
released.
The card, which is the size of
a postage stamp, will go on
sale for $800 (£490).
The launch comes a decade
after the firm released a
512-megabyte (MB) SD card
with one-thousandth of the
space.
Experts believe SD cards
could eventually hold up to
2 terabytes (TB) of data,
about 2,000GB.
The new card is aimed at
film-makers shooting in the
high-quality 4K format.
The 4K format - which is
four times the resolution of
HD - requires large file
storage. Depending on
compression, a single
minute of 4K shooting will
typically take around 5GB of
storage space.
"4K Ultra HD is an example
of a technology that is
pushing us to develop new
storage solutions capable of
handling massive file sizes,"
said Dinesh Bahal, vice-
president of product
marketing at SanDisk.
The SD card format is one
of the most widely used
standards of flash storage,
popular with digital cameras,
camcorders and other
mobile devices.
While camera types,
resolutions and settings
vary - a 512GB card could
potentially hold around 30
hours of HD video.
Cloud worries
John Delaney, a senior
mobile analyst from IDC,
said innovation in physical
storage was critical to the
future of our devices - even
if a lot of people are turning
to cloud storage instead.
"The thing that is driving
cloud storage is multiple
devices usage - which solves
the, 'Where's my stuff?'
problem: if you use cloud
storage for everything,
whatever device you have
with you can be used to
access your content."
But he added: "So far there's
still a strong preference for
local storage.
"People just feel more in
control and more able to
rely on being able to access
the content when they
literally know where it is.
"Storing in the cloud means
you literally don't know
where it is."
Mr Delaney added that
recent high-profile security
issues around cloud storage
- such as the celebrity
picture leak last week -
would play on the minds of
consumers.
