Managed to get hold of a Seagate 4GB Photo Hard Drive and did a mini-experiment as follows:
Objective:
Test the speed of this card against a popular brand of simliar price.
Equipement:
1.6Ghz Centrino Laptop on Win XP Pro
USB2.0 Hi SPeed All-in-one reader from Agilent Technologies.
4GB Photo Harddisk (~$200)
1GB Sandisk Ultra II (~$190)
Test rules:
Copy a folder of 107 files (all jpegs) worth 268MB.
Timer start at the same time mouse button is released.
Timer stopped when the 'copying' folder disappears.
System restarted before commencement of each test.
Here are the results.
2GB Sandisk Ultra II
Write: 1min 54sec
Read: 1min 02sec
4gb Seagate PhotoHarddisk
Write: 2 min 10 sec
Read: 1 min 14sec
Difference:
Write: 14 Seconds
Read: 12 Seconds
Conclusion:
There didn't seem to be a very big difference in transfer speeds. I would say the photo harddisk is quite fast Comparing the cost of $/GB I think the seagate Photo harddisk is a good value-for-money storage supplement to the normal CF cards.
Other comments, it takes the Photo Hard Drive <1sec to start up in a sleeping.
When the review(playback) button is pressed when the camera goes to standby, there is a little noticeable delay (<1sec) before photo pops up on display.
However, when camera is pre-focussed, and camera is allowed to go into standby and shutter button is depressed fully, the image is captured immediately with no noticeable lag compared with solid state CFs.
If review is pressed while camera isn't in standby, image pops up immediately. Browsing images on camera did not show any lag with images popping up almost instantly. IMO, slightly faster than the Ultra II but there's no way I could time something in milliseconds to show this.
Thanks for reading.
*Disclaimer:
- I'm not affiliated with Seagate nor Sandisk.
- This is an unofficial test and was not intended to be a benchmark.
- If you have any unrelated comments about the test (eg: the colour of the products looks ugly, it weighs 20g more than my other CF, it isn't water proof, it doesn't make coffee etc.. I would appreciate if you post it in kopitiam
- Thanks
