Is a 4gb sd card "better " than an 8 gb one ?

Question

I remember when the larger compact disk cards came out they seemed to fail more often than the smaller sizes. Is the 8 gb perfected ? Does it have problems ? Also, is the time to "save" photos longer than the 4 gb takes ?

Answer 1

A 4 GB cad has 1/2 the storage of an 8GB card..end

Answer 2

well i'd have to say the 8gb because it has more memory and the time to save photos isnt that long.

maybe the fail rate is about 34% but hopefully that doesnt happen to you.

well thats just my opinion

Answer 3

I don't know where you heard that larger cards fail ... they don't.   I have been  shooting using digital memory cards for over six years and have NEVER had one fail.  The cards are designed to perform perfectly through 20,000 format cycles ... those who experience file and card corruption are not formatting their memory cards on a consistent basis (see work flow below).

I use 16GB and 8GB cards because  my camera produces files that are so large that I get 173 images on a 8GB card.

The problem you may be referring to is the tendency of non-photographers deleting images from their cameras memory cards (usually to make room for more instead of carrying a spare card) and then "accidentally" either deleting all their image files or formatting the card.  Falling into the habit of rarely copying the images to a computer can further exacerbate the problem.

I use large cards because I need them ... I use smaller cards when I am only going to shoot a few images ... like products where 30 or so shots are enough.  The work flow is as follows ... start with a recently formatted card, shoot your pictures, copy them to your computer, check your computer and make sure all the images are there, format the card using the format feature in the menu of your camera.

The "speed" at which cards save images have more to do with the camera.

* Cameras usually do not support more than about a 40x rate.

* The size of the sensor and pixel count will cause variations in individual write speeds.

* You can save money by purchasing "slower" memory cards.

* At this time there may be no cameras that can even use the potential of a 133x card.

* If you can afford them, eventually I am sure at least pro cameras can eventually will support those and the higher speed 300 plus x cards

Answer 4

The time to save depends on the brand. You would have to read the box to tell that, some are 15 megabytes per second, some are 30, etc. The only difference between the cards is the size and possibly the speed to save, but that would depend on brands and such. You won't see any image quality difference.

NO to each question
