    I have rooted (using CyanogenMod7 rom) and have a partioned 8gb memory card. It's starting to fill up as I get more and more use of out my phone since rooting, so I'm about to buy a 16gb memory card.

    few questions...

    1. is there a big and noticeable difference between a class 4 and a class 10? I know the technical side of it, but in use, is it a big deal?

    2. Does it matter really if it's a "name" brand? The one I'm looking at it is a JoyTech, but the seller has 100% positive ratings, and has sold lots of the same type of card with good feedback

    3. I've switched memory cards before, pre-rooting, and it was just a matter of copying data from card to card and off I went. Is it the same post rooting? What about the EXT partition?






    Thanks in advance for all your help :)

    1. No. Infact the desire is limited to class 6.

    2. Yes it really matters. I may be wrong but someone here had very disappointing results witha cheap card and that make rings a bell

    3. If its partitioned, nandroid backup, copy FAT32 PC, Partition new card, copy data back, nandroid restore.

    so the nandroid backs up the EXT partition as well? Didn't realise that. OK... that seems easy! :D

    Any recommendation on brand of memory card?

    Just avoid ebay. Get from a reputable dealer. Play, Dabs ebuyer etc.

    Me! Me! It was me! :p

    Yeah, had 2 cards now, both Joyflash, from the same seller (based in Guernsey) - 1st one just plain didn't work, 2nd one seemed to work ok on the pc but was slower than a paralysed sloth in the phone - my class 2 PNY equalled its results. It's now gone funny on the pc too (takes ages to be recognised in the reader) so that's winging its way back as we speak.

    I was surprised though, 'cos there's a couple of threads over at xda full of people buying those cards off that person with great results - but not me. Bugger. :(

    @SURoot - I have no doubt you're right about the Desire hitting the buffers at a class 6, but round and about I've seen screenshots of a speed measuring app (can't remember the name, sorry) showing up to about 15mb/sec - dodgy app/buffered result/photoshop? :eek:

    Write! :eek: There's a screenshot about half way down this thread, and various verbal references to those sort of speeds elsewhere in it - although it's all brought into disrepute by one loon claiming 67mb/sec read... :rolleyes:

    People in that thread (and one on another forum, can't remember which one though!) seem happy enough with their cards - I thought it was worth a punt at the price, but to be honest I didn't even get what I paid for. Maybe I was just unlucky - reading reviews on Amazon, there's a proportion of people unhappy for just about every card there is, regardless of brand.

    But as a wise man once said, Caveat Emptor. :)
