Sony has introduced a new line of XQD format version 2 memory cards,
the G Series. As with other XQD cards, the G Series promises fast read
and write speeds that are able to match the demanding needs of select
cameras, such as the Nikon D4 and D4s.
In turn, Nikon has announced that the D4s will fully support Sony's
version 2 XQD cards, with improved write speeds and Raw buffer
capacities. With previous XQD cards the D4s could capture 133 12-bit NEF
files before filling the buffer. With the G series cards the buffer
capacity is increased to 200 shots.
The G Series has a 400MB/s read rate, which is faster than the
preceding S Series' 180MB/s and the N Series' 125MB/s. Write speeds, as
expected, are slightly slower at 350MB/s. The G Series cards are offered
alongside a USB 3.0 adapter, which Sony says can transfer 60GB of data
to an SSD in 3 minutes (CF takes 7 minutes in comparison).
The G Series cards use a second generation PCI Express interface, and
are available in three capacities: 32GB (model QD-G32A), 64GB
(QD-G64A), and 128GB (QD-G128A). The 128GB card is unique among Sony's
XQD format offerings, with both the S Series and the N Series tapping
out at 64GB.
Sony does not have prices listed on its website, but the cards can be found at various retailers. B&H,
for example, has the cards available for $163.50 USD for the 32GB
model, $363.95 USD for the 64GB model, and $799.95 USD for the 128GB
model.
