FLASH MEMORY
COMPARISON
Windows XP Performance
In these tests, we used
the following hardware platform, and Windows XP SP2:
We used a
Y-E Data YD-8V07 combo FDD as our USB 2.0 card
reader. We used Atto Mark for testing each of
the products. Queue depth was set at 2 because
hardly more than one request at a time is sent to
these storage devices, especially when used in
consumer electronics products such as digital
cameras or MP3 players.First, here are the test
results for the Compact Flash cards:
The Crucial 4GB CF
card had fairly fast read speeds, but write speeds
were on the slow side.
The Kingston 512mB CF
card had the opposite scores - fast writes, but
sluggish read speeds.
The SanDisk 128MB CF
card had very fast read speeds, and equally slow
write speeds.
Lastly, the SanDisk
Ultra II locked in with impressive read and write
scores throughout.
If you tend to take many
photos in sequence, write speeds are very important.
In those rare cases when MP3 or PMP devices use CF
cards, read speed is usually not very critical.
But when transferring many files from one place to
another, read and write speeds can save plenty of
time.
Next, we look at the
test results for the two USB disk drives:
The Cruzer mini showed
mini-speeds as well.
The Data Traveler
Elite just blew away its competition here.
Amazing speeds!
We'd just like to
point out the included software above, and a cool
BLUE LED which indicates activity below. By
the way, just don't lose the cover.
As for USB disks, the
intended purpose is more straightforward - shuttling
files from one computer to another. Some may
choose space over speed, while power users may
require more speed than space. Nevertheless,
the tests above show that premium products deliver
premium performance.
