Accessories 16Gb Class 6 MicroSD Baragain!

^ i got that card. the packaging is nice and the card itself feels very solid. works pretty good so far on my phone.

the read speeds are very decent and are about 10 m/bs plus but the write speeds so far has been underwhelming for me tbh. i didn't use any software so i was doing rough 'tests' and was able to deduct i was getting just about 6 m/bs i.e sometimes lower, sometimes higher, not very consistent.

make sure you format it properly on your computer first tho.

My ebuyer / lexar card arrived this morning.

I can confirm it definitely is class 6 labelled.

I've run h2testw on it and it has sustained 9.12 Mbyte/s across the whole capacity with no errors, so seems to exceed the spec of class 6.

Card comes with some crapware on it from lexar, so it needs formatting before you put it in your phone.

Will try 720p on it shortly and post back.

sorry, i had replied to this but i've no idea what happened to the post!

general use the card seems fine. 720p video is still capped at 19.6fps - i think this is by design and not a limit of the card. there are no picture breakups or anything when watching 720p video.

I don't really trust the sd card speed app - it says that it's a "ClassUnknown" and write speed is 9 MB/s but read speed is only 5 MB/s - which is blatantly rubbish - it's unheard of for read speed to be slower than write. h2testw on windows found the read speed to be 15MB/s and the write speed to be 9 MB/s - those are believable numbers.

The video shouldn't be capped at 19.6fps afaik.At least for me,Windows 7 says most of mine are 22 fps.

the video *shouldn't * be capped at 19.6 fps, but that's what ffmpeg says (which I trust more that windows media player).

I also know that the class is based on the minimum write speed; however, it just does not make sense that read is slower than write. That's not how flash memory works. It does not make sense. Read speed is always higher than write.

As mentioned in a previous post, I have the same card as you and get exactly the same write speed.

Using the SD Speed Test on my Desire the app reports that the Write Speed is 9.0MB/s and Read Speed is 13.0MB/s, but also is an unknown class.
Testing using Windows had exactly the same write speed as well, so seems fairly consistent and reliable.

As also mentioned, my 8Gb SanDisk Class 4 card was achieving write speeds of 12MB/s but I have had absolutely no problem with the new Lexar 16Gb SD card and am perfectly happy with it.

2 different people with 2 different memory cards are always gunna get different results anyway so it's all subjective.;)

Not really; because my point was that I suspect that the desire itself is the limit of frame rate, not the storage media. At the end of the day, the SD card knows not nor cares what the framerate is, only the actual bit rate.

modern video codes are quite capable of adaptively changed compression "quality" to adhere to a bit rate requirement - but not changing framerate (most codecs don't support a variable frame rate anyway).

Hence, my suspicion is that the desire itself is limiting the frame rate to around 20fps - due to an internal limit (perhaps to do with the camera itself).

Do you find the HD video playback choppy?

Hmm after reading what he said I guess not but the reason there are 23 left is because I just bought one from the 24 they had :D Coming tomorrow :cool:
