i ordered myself a bigger SD card.

Transcend 4gb class 6 card for $15 :dancing banana:

FYI - I love transcend and they are a huge Flash Manufacturer.

$15? Thats a great price. I have 2 of those and paid double that for mine. :\

Class 6 is currently the fastest speed offered for SDHC cards.

one better than 5

Not all class 6 are created equally.

I just got a Kingston 4GB C6 (only because it was under $10 shipped) and it is so slow!!!! It takes over 30 seconds to dump my full XSi buffer = :mad:

Maybe I'll just use it for JPEGs

6 means 6mb per second I believe.

6mb/s is the minimum write speed for class 6. Many makers are quite a bit faster. These transcend cards are 12.5 mb/s write for example. Unfortunately there isn't much testing on SDHC memory speeds right now and no higher specifications.

according to this link posted by ben my class 6 kingston is not 6mb/s
http://www.robgalbraith.com/bins/camera_multi_page.asp?cid=6007-9424

JPEG - 1.982MB/sec
RAW - 2.911MB/sec

:sadbanana:

The transcend 4GB C6 tested at:
JPEG - 8.285MB/sec
RAW - 10.949MB/sec

While somewhat useful, that guys tests are very flawed.

Jpeg and raw should not produce different data throughput. He's measuring something very dependent on the camera. Data is data to the card. It can be jpeg, raw, or excel spreadsheets. The proper way to bench is get a USB reader and use a disk benchmark test tool. Plenty out there that do this.

While the relative speeds might be somewhat accurate, I wouldn't take his absolute numbers to mean anything.

^ :huh:

his tests are incredibly accurate in terms of write speeds of specific cameras and specific cards. Obviously that's different than the speed of just the card, but if you're going to be using it in a camera who gives a ****? I don't care how long the DL takes at home to the nanosecond, but how fast a card can clear a buffer is important to me...

^ truf!

He does have another page where he tests each card in card readers. My Kingston 4GB C6 gets 15MB/s to 21MB/s depending on the reader. I'm definitely not getting those speeds in my XSi

yeah i have seen his tests perform as stated, most of my cards are to the letter with his results (ultra II 2gb being faster than an extreme III 8gb)

That's great if you're using that card in that specific camera. However if you want to benchmark the card's performance and not the camera's performance you want to use a benchmark based on something that isn't going to **** with your results. What do I care about the write speed on a canon camera when I'm using it in a pentax or nikon?

Point being that the camera is often the limiting factor in performance, especially so on lower end DSLRs. Why cripple your card readings with it?

Edit- and DL speed means jack. Its write performance we need to worry about.

I AM!!!!!!!!!!

if I want other types of tests, I don't use his site... :wave:

I'm interested now- did any of the cards swap relative places with given his hand testing margin of error from camera to camera? Or did they all perform relatively the same from camera to camera, brand to brand?

not sure, I only check the cameras I own when I buy them or when I'm ordering cards. :lol:

From my quick survey it doesn't seem they change much. I'm too lazy to enter it all in a spreadsheet to check for real though.
