For example Transcend 8GB card requests much more power than e.g.
Kingston 8GB card (200mA vs. 25mA i.e. ~8x more, but due to steps specified
in the SD spec, in reality it could be only ~4x times more). Don't know
whether this is related to bug here though, both memory card slots
should (naturally) provide the maximum amount of power required
by the cards.
• Current Consumption
The current consumption is measured by averaging over 1 second.
‧ Before first command: Maximum 15 mA
‧ During initialization: Maximum 100 mA
‧ Operation in Default Mode: Maximum 100 mA
‧ Operation in High Speed Mode: Maximum 200 mA
‧ Operation with other functions: Maximum 500 mA.

Look at Bugtrack https://bugs.maemo.org/show_bug.cgi?id=1204#c75 (comment 75 from Nokiaman)
And I'm look in to Transcend SDHC card specs:
500 mA!! Splendidly!
Thus, not every card is intended for a IT...

Just throwing my 2 cents in, I had two A-data 8GB SDHC cards and they both went from flaky to dying. My opinion is that I would avoid them, given my experience.

I did a series of tests using the battery-status program and several SD cards. The other cards I have are 2 Sandisk 1GB, 2 Sandisk 2GB, 2 Patriot 8GB, 1 PNY 512MB, 1 Nokia 256MB. I tested my n800 with no cards first and the battery drain on idle was .4% per half hour, when testing all the other cards in the same manner, they all came in at .4% per half hour as well, so no additional battery drain. But the Adata card comes in at 1.6% per half hour of idle, or four times the amount of battery drain over the other cards. This is even after reformatting it, once as fat32, once as ext2, no change. The card functions fine in every other way and I get no errors on running checks.
Does anyone else have Adata cards? they might want to compare their battery drain on idle to the NIT with no cards using the battery-status app.
