UDMA
= ULTRA DIRECT MEMORY ACCESS what’s in it for photographers?
UDMA is a
protocol developed by Quantum Corporation in conjunction with Intel
that supports burst mode data transfer rates. You might be
wondering what is a protocol? A protocol is an agreed-upon format
for transmitting data between two devices. There are a variety of
standard protocols from which programmers can choose. Each protocol
has advantages and disadvantages; for example, some are more simple
than others, some are more reliable, and some are faster. From a
user’s point of view, the only interesting aspect about protocols is
that your computer or device must support the right ones if you want
to communicate with other computers. The protocol can be implemented
either in hardware or in software.
What does a
UDMA CompactFlash card do for you? A UDMA memory card dramatically increases card-to-computer transfer
rates when paired with a UDMA-enabled reader… (Hoodman’s RAW) UDMA
memory cards will download 2GB of data to your computer in just 60
seconds via a RAW FireWire UDMA enabled reader from Hoodman. If you
are a USB 2.0 person, the same 2GB of UDMA data will download to
your computer in 2 minutes via a RAW UDMA USB 2.0 reader. Hoodman’s
RAW UDMA readers are backwards compatible with non-UDMA CompactFlash
cards.
How do UDMA cards work in non-UDMA cameras?
UDMA
CompactFlash cards are backwards compatible with all Digital SLR
cameras designed for CompactFlash cards. The UDMA cards will max
out the performance of your non-UDMA camera and give you the
dramatic increase in card-to-computer transfer rates described
above… a huge time saver.
How do UDMA cards work in UDMA cameras?
To date:
the Nikon D3, Nikon D300, the Canon 1DS Mark III and the Olympus E3
are the new cameras which utilize the new UDMA protocol. UDMA cards
are designed to maximize the performance of these new cameras.
Can I use my old CF cards (non-UDMA) in a UDMA camera?
Yes, you can
use your non-UDMA cards in the new UDMA cameras. You will not
maximize the performance of your new camera by using a non-UDMA card
and you will have to spend a lot of time waiting for your slow cards
to transfer data to your computer.
Are
UDMA cards more reliable?
Hoodman RAW UDMA
cards have had ZERO in field failures since their launch in January
2007. Hoodman RAW is the only CompactFlash card built in the USA.
Hoodman RAW is the only CompactFlash card sold exclusively through
Professional Photo Dealers. Yes, RAW costs a bit more, Hoodman is
betting your photography is worth it.
