Objective:
Determine if a "no-name" card, PNY can stand up against a Sandisk Extreme III
Goal:
Examine the read and write speed of both cards with my setup.
Conditions:
Camera
Nikon D80
Manual Mode, Manual Focus
Shutter: 1/200
Aperture: f4
ISO 3200
NR OFF
Reader
Dell Inspiron e1705
Windows XP 32
T2300E
2GB DDR2
Integrated TI SD/SDHC Reader
Read Speed Procedure
create separate folders for each card on the desktop
21 same shots taken full resolution raw, filesize 11.7MB +/- 100K.
Remove card from camera, insert into PC.
Wait for windows to detect and open the explorer window
select all, drag, drop, start timer on click release
Read results
PNY SDHC 4GB: 243MB in 26 seconds
Sandisk Ex III 2GB: 244MB in 26 seconds
For all intents and purposes a tie.
Write Speed Procedure
Place card in camera.
Format card.
Using shooting conditions described above, except using JPEG Fine and Small as opposed to raw, shoot until the buffer fills (r00 on top display and audible difference observed)
Write Results
PNY SDHC 4GB: 11 Seconds, 33 Frames
Sandisk Ex III 2GB: 34 Seconds, 100 frames(100 frames seems to be a firmware limitation, not the buffer actually filling.
Results/Discussion
The read speed was clearly a tie. The write speed may need an explanation.
The write conditions were as favorable as possible for the cards. I may get bored later today and do tests on medium and large.
The Sandisk card wrote fast enough to keep up with the buffer until the camera could no longer shoot due to firmware.
The PNY card was unable to keep up with write demands once the buffer was full. This is poor write performance, as the images were JPEG small, 1936x1296 which is a 1.2MB file size.
The Sandisk clearly wipes the floors with the PNY card on writespeed
Long story short: If you need fast writes (sports, etc) you don't want to get a PNY card.
Updates:
JPEG Medium/Fine:
PNY: 17 frames
Sandisk: 100 (firmware max)
