Got an 8GIG MicroSD card, and...

---

My Hero came with a 2GIG card ( I'm not sure what class ) - it was fine but too small.

After a bit of research, I found that the higher the class the faster the card ( ie class 6 is a faster card than class 2 etc ).

I formatted the new card in the phone.

So I copied all my old card files to my computer, then copied them over to the new card.

Put in the new 8GIG card in my phone and it mounted no problem and I had all my music and photos.

BUT -

As I can see, it seems to be a lot slower than my old card. If I go to my photo album, it will load as a preveiw grid. This used to happen pretty quickly, but on the new card, the grid squares are grey, and then start to load up with the photo images.

Any ideas why and ways to fix this?

cheers all

did you buy the new card from an auction site? I hate to suggest it, but there are a lot of fakes around...

Errhhh, this is actually incorrect.

All the class means is that your card is guaranteed to write at certain minimum speeds.

Class 2 - 2mb/s
Class 4 - 4mb/s
Class 6 - 6mb/s

So, if you buy a genuine class 6 card, you are guaranteed that it will write at 6mb/s but that doesn't preclude it from operating faster than this minimum.

A good quality class 4 will often write at 11 or 12 mb/s, more than double the class 6 minimum. You can expect that a good quality class 2 or class 4 will often outperform the class 6 minimum, whereas as poor quality class 6 will perform far closer to its minimum requirement.

When buying an SD card, don't just look at the class - look for independent reviews. For example, http://www.davidgilson.co.uk/2008/12...cro-sdhc-card/, which shows a class 2 card running at speeds well in excess of class 6 minimums.

This is another case of the Hero having problems with certain SDHC cards.

The thumbnails for the Album are not being created and stored for some reason, and i can almost guarantee this is what's happening to you.
I've had to go back to using my old 2gb for now, as my 8gb Sandisk Mobile Ultra Class 6 was performing poorly when viewing my photo albums. We're still trying to work out why the Hero is not liking these newer cards...

I'm watching with interest....

How sad, I should have noticed this before. Having read your article, I immediately test my two SDHC cards. The finding changes my fundamental view on class numbers:

Transcend Micro SDHC, 8G, Class 6: 9.1MB
Sandisk Micro SDHC, 8G, Class 4: 14.9MB

Note 1: The Transcend card is from someone who sold me a second hand Google G1.
Note 2: The Sandisk card came with a tiny red reader (Like this), bought in Hong Kong

The speed test is carried out using the Sandisk reader in conjuction with the card benchmark software called "ATTO". To my surprise, the read/write speed of this tiny reader is, amazingly, faster than the internal card reader.

That would be this issue.

Still no real solution yet, but its not an exclusive problem.
