Ok, I searched. Couldn't find it.
PLEASE, I'M NOT ASKING ABOUT CAPACITY. I understand MAX is 32GB Micro SD for the 9650.
What I'm trying to find out, is what is the highest/fastest Micro SD CLASS specification supported by the 9650 currently & also if that will change with newer OS update(s).
As I understand it, the higher the class specification, the faster the data transfer rates, the faster the performance related to moving data on/off the card. (The hardware & O/S of the device needs to support that level, or "CLASS" of M-SD card to gain the benefits, though).
Basically, is the phone able to realize any performance benefits (worth it for me to pay the extra $) from use of a CLASS 4, CLASS 6, micro SD CARD, or would this be a waste of $, given the phone's capability?
(Should I just get a CLASS 2 CARD & be done with it? Faster is better & I'm willing to pay for performance, I just don't want to pay unneccessarily for performance in the Micro SD that the phone cannot use.)
Please any BB techies out there - chime in...

Wow, no BB geeks? Nothing but cobwebs, here... so I went s'plorin'...
No hard facts, vis a vis a statement/spec from RIM, but anecdotally, the higher class rated cards do perform better, apparently.

I use a Class 2 M-SDHC card w/ my 9650 and it works fine. I know someone that uses a Class 4 M-SDHC but I haven't heard of any comparisons between classes. Using a Class 2 seems to work well enough for me, so I'm not looking specifically to get a Class 4 when it comes to transferring data.
I'm not a BB techie but hopefully one will pop in to fully answer your question.

Ok, said I would report back...
I received my new 8GB, Class 6 MicroSD card. It's made by "TOPRAM," kind-of a lesser known manufacturer - so I took a chance, but I'm glad I did. The price was less than 1/2 that of the bigger players in the memory business, but so far, it seems like the only thing I suffered for this decision is a slightly heavier wallet...
I transferred my data and installed the new card. It's not a scientific assessment with number & stats & the like, but...
The "Class 6" card is noticeably faster (than the "Class 2" card it replaced) for me on data transfer and data access functions, which for me, improves the overall user experience.
Two thumbs up for (Class 6) specified cards, afaic.
