Default Class 6 or Class 4 microSD card?

Please Login to Remove!

Will I notice a difference on the Bold if I use a Class 6 microSD over a 4 or 2?

Thanks in advance.

The phone can't handle media that would excede the transfer flow of even a class 1 card, so if I was you, I would just go with whatever is cheaper

Not true. I bought a cheapo 2gb card, and then upgraded to a class 4 4gb card and noticed a huge difference.

That said, id imagine id see faster load times with a class 6 over a class 4 as well.

I was wondering this as well. Will the electronics in the Bold take advantage beyond Class 1.

We may test at work and see, but all I have are Class 2 and Class 4 I think.

The bold per se aside, it would make a difference when using the computer to transfer to/from the card, as well as when popping the card directly into a reader.

also, to prevent confusion, there's no such thing as class 1 cards.

With my experiences, I haven't had any issues streaming 1020p media from my class 2 card onto my xbox (and out to my TV) and I don't see anything on the bold (or any phone in existance ATM) requiring more bandwidth from the card than that.

Like you all have mentioned, it makes a big difference if you're transfering files from a computer that are multi gigabytes. But I also don't know any exact numbers because I just "set it and forget it"

Thanks in advance.
There are noticeable differences, but not as huge as in a digital camera or desktop card reader.

For example, shorter save times for photographs and videos were one of the noticeable benefits. Also the lag caused by thumbnail generation gets slightly shorter. Also copying files to/from the BlackBerry in Mass Storage mode -- like copying 500 megabytes of video files. There are, however, a clear point of diminishing returns, since the Bold processors are not as fast as a desktop quadcore CPU, for example...

A faster card will have a noticeable benefit even if not as dramatic as hoped -- if it's only $10 more, it's definitely worth paying the extra $10 to take consecutive photographs slightly faster.

Important note: Different class 2 cards vary sometimes dramatically: Some class 2 cards are pretty good -- they just might fail in one class 4 or 6 metric but still have the transfer speed of a class 6 card "most of the time". That's been my experience. Classes are just standards that encopass multiple metrics such as sustained transfer speed, random-access speed, including sustained speed through fragmented files, etc. A good brand of Class 2 card may have Class 6 speed on un-fragmented files, but not on fragmented files, which disqualifies it from being labelled as Class 6.

Bottom line: Yes, faster cards makes a difference. But classes are a bit 'fuzzier' than it looks on the cover.

I appreciate this write up much. I have looked, searched ect for "Class information" and am having trouble to dial into a spec sheet for what separates the classes and what they look for ect. Any chance you have anything detailed like that expands on this or can point me to the right direction?

Thanks in advance,
