Transcend claims it refers to read speed. See my post. But for cameras, who cares about read speed?
Anyway, if the card boast of a ultra-fast read speed, shouldn't the write speed be similarly ultra-fast, even if it is not 150x. What is the point of having a card with ultra-fast read speed but ultra-slow write speed?
Memory isn't only for camera usage. In fact, most normal people's usage would be to read, not write to the cards. Think video, multimedia stuff. Not in Singapore, but other more advanced countries of the world.
Alot of people would prefer ultra high read speed to ultra high write speed.
As for your problem, I'll put it to 100% user problem.
S3IS is an old old device. It cannot support memory cards greater than 4GB. I doubt you read your instruction manual. I believe it's stated that it cannot support memory cards greater than 2gb.
In fact, I wouldn't be surprised if they stated that it cannot support greater than
1gb.
Most devices now do NOT support 4GB cards. Those that do, stick to the SDHC guidelines.
Keep in mind, Caveat Emptor. If you're a faulty purchaser, don't blame the seller.
erm, my transcend 2GB 150x SD card is averaging 5MB/s. i think the card reader is the problem. but then it states that it supports even sandisk extreme III!
sandisk extreme III @ 5MB/s? so much for high speeds!
spiegel, what usb card reader are you using? i don't want to buy another card reader just to find out that it "supports" high speed cards but can only run at low speeds...
You're using USB2 card reader.
The uplink bandwidth isn't as big as you hope it to be. Do you know the max theoratical speed of a USB2 connection? it's 120Mb/s / 8 = 15MB/s. Even then, a realistic expectation would be 7 - 8 MB/s. If your system databus is occupied, it can slow down to 1 - 2 MB/s.
Best solution would be to reinstall windows clean if your system keeps giving you low read/write speeds. 90% chance you've some unwanted software running in it. Of your Anti-virus is slowing it down (writing to an external device etc).
