Does swapper or swap partition will slow down the phone, even my sdcard was class 6 or 10? and does using swapper will degrade my sdcard lifespan?
yes it will degrade or less the life span of your SDCARD thats why higher class or sdcard is needed so that the reading speed its like just normal even you have swap
i have a 8gb class 4 using swap
works fine,
no issues about it

Just an off the wall question for everyone. What kind of micro SD card are you guys using? Anyone try a class 10 card versus a class 6 card and notice a different in the Vibrant??
Still using the standard..don't see a point until apps2sd is enabled...at that point ill probably just use the class 6 8gb from my mt3g

It's kinda complicated but here are a few things to note. First most people notice a decrease in speed when going from a 8gig class 6 to a 16gig class 6. This has to deal with the fact phones only regulate a certain amount of voltage to the microsd slot. In order to get more storage into the same amount of space more voltage is needed to keep it running at a class 6 rate of speed. The reason the phone doesn't adjust it's voltage is because it causes more heat (which can of course cause damage to the phone) and it waste more battery.
Second because of this voltage regulation you will never notice the difference between a class 6 and a class 10 card while inserted into the phone unless they figured out how to get class 10 speeds on lower voltage. So this means that you should never read stats presented by the manufacture and actually try to get people who own the card to do a speed test. If we can get every card benchmarked while inserted into a phone then we can have a better understanding of what card is actually faster.
what's the best and most suitable SD card class for running android?
what i understand (and correct me if i'm wrong) higher class cards are faster but take more battery power so causes shorter battery life and heat.
lower class cards on the other hand are slower but consume less energy.

It's really all about preference, but I think a class 4 will be more than enough. I've read that class 6 or more is only really needed if you plan on using the card on a camcorder for hd recording, but I just ordered a class 6 16GB myself
I got a PNY 16gb class 10 microsd card from Play.com last week for my SGS2.
I've read on these forums that higher speed rated cards have different charateristics, i.e. trade off access time for throughput. SD tools confirmed very fast throughput (13MB write/24MB read) however after putting the card in and putting about 2gigs of content on it, the phone started to behave very strangely.
The phone would get very hot with no obvious activity and remain very hot with the battery running down very quickly. Sometimes randomly, but always being triggered by SD Tools (which would hang and have to be killed with task manager).
I had been suffering random reboots (about twice a week) before then, so to rule out a faulty phone I had it replaced for new at car phone warehouse.
However, the exact same behaviour with hot phone, battery running down alarmingly quickly happened with the new one. Only way to resolve was to pull the battery.
I've since swapped back to an old 8gb class 6, which while a tad slower (9MB write/19MB read) doesnt cause the phone to behave badly.
Maybe it´s the app and not the SD card......................
Perhaps a stupid question, but I was wondering if running CM7.1 from an SD card will noticeably drain the battery more than running it from the internal EMMC? Is there any benefit battery wise to running CM7 on EMMC?

SD cards are very low power devices. They only draw power when being read or written to. I do not think you would notice any difference. The internal storage device is also an SD card, just permanently installed (emmc - embedded multi-media card). Besides, you probably would have an SD in the slot anyway. But some say there is a slight speed difference, especially for certain SD cards.

Off topic, but I've noticed slow write speeds on my SD lately. I bought it close to 2 years ago when 16 Gb class (10) cards were still fairly expensive. I never did see a minimum of 10 MB/s which should have prompted me to return it immediately. My card always registered around a class (6) status.
Anyway, as of late my Kingston card has slowed to a crawl. I decided to test it both in and out of my Evo and I'm getting an average of 1.4 MB/s. Even my old Sandisk 8Gb class (2) card scores a consistent 2 MB/s.
I've heard of flash memory eventually going bad, is this a sign of an eventual card failure? I also noticed in my testing, the write speeds are not sustained. The graph shows peaks and valleys which averages to 1.4 MB/s. My other cards are flat and consistent.
