A few days ago, SanDisk announced a 32GB SDHC flash media
which boasted not only the highest capacity on the market, but also the fastest
speeds -- the Ultra II 32GB SDHC memory card will have a maximum read rate of
15 MB/sec and a write rate of 10 MB/sec.
Today, SanDisk does not have the fastest 32GB SDHC card on the block as
Panasonic has announced its own 32GB
SDHC flash media within the Class 6 speed bracket. There are 3 classes of
speed associated with SDHC cards. Class 2 specifications list transfer rates of
at least 2 MB/sec or higher, Class 4 specifies a speed of 4 MB/sec and up, and
a Class 6 memory card would have speeds of over 6 MB/sec.
Though SanDisk's recently announced product falls under the Class 6
specifications, Panasonic's RP-SDV32GU1K 32GB SDHC card boasts maximum data
transfer rates of up to 20 MB/sec under optimal conditions. It also states,
since this 32GB card is manufactured using industrial-grade memory, the
RP-SDV32GU1K can withstand a wider range of temperatures; -13 F to 185 F as
opposed to 32 F to 158F of typical consumer-grade SDHC media.
Panasonic's RP-SDV32GU1K will be available in April, according to the press
release, and will be aimed at shooters of high-definition video and
professional photography. Pricing has been set at a whopping $700, twice the
amount of SanDisk's
