Default 30mbps vs 15mbps for 32g SDHC?

Does anyone know if the EVO would be able to take advantage of the faster 30mbps read/write? speeds of the Extreme III version of the 32gig SanDisk card?

Or should I save some money and stick with the cheaper 15MB/s Read, 9 MB/s Write version?

Thanks!

Doesn't that depend on how your accessing or using the memory? Not sure about how phones work but just because you have a faster write on other data storage doesn't mean it's going to improve your experience. If you're writing/reading at a higher rate than information can be displayed or used, then you're not really saving time.

That said, I'm pretty sure being able to read/write at the highest speed will just ensure that your data card isn't the reason things are slow or lag.

I'd think the read/write would stand out most when taking max resolution photographs as lag tends to show up there more than it would in other smartphone functions.

To illustrate, faster read/write (bigger, more open pipe) would not allow you to drink faster if you can't match the throughput all the way. That's why there are memory buffers in electronic devices.

Yes, I agree completely. I've looked over the released specs for the EVO but was not able to find any information on the speeds at which it is capable of reading/writing to the card.

When I started looking for cards, I noticed that there are several different speeds (and hence several different prices) for the 32g cards. Just wanted to make sure that if I bought the cheaper, slower, card that I would not be disappointed with the results if I were to try and take advantage of the HD video capture/playback.

Thanks for your reply!

Well Blu-ray is maxed at 1920x1080 at 40mbps. Since you will be doing a smaller resolution you won't need that kind of bitrate to match that quality. Likewise, if your source is anything other than really high quality video like that, it would be overkill to encode at that high a bitrate.

Long story short, for video playback at least, you will probably never need 30mbps unless you are using it to feed a monitor with the absolute highest quality video you can get the Evo to play.

Are you sure you are looking at MicroSD cards? Because I'm pretty sure Sandisk does not label any of their cards Extreme III in the MicroSD category.

Also MB is 8 times as big as Mb, so if that is true you really are not comparing apples to apples. Like stated above blu-ray maxes out at 40Mb/s but that's only 5MB/s.

Where are you seeing two different speed 32GB MicroSD cards? There's only the one 32GB MicroSDcard that I know of.

Most that I have seen are in the class 2 category. (32 GB Name brand cards anyway.)

You, my friend, are correct. I should have looked at the images instead of the specs for the cards when I did my search. You are correct, I can only find one MICROsdhc card.

Guess that answers my question =)

32GB microSD cards are still a little out of my price range. But I did pick up a 16GB Kingston class 10 card. Reason being, I know I'll be transferring Gigs of movie files to and from the card routinely.
