I was about to buy a memory card for my samsung wave...but I have read this in phone specs.-->"Expansion:Interfaces: microSD, microSDHC, TransFlash"
" Supports High Capacity (SD 2.0/HC) memory cards with capacity of up to 32GB"
Now I am confused...about the types ( microSD, SDHC and transflash). Which is the fastest card out of these? and the cost difference?
You won't notice much of a difference between the three, at least in my opinion. I've used both microSD and SDHC and there wasn't any noticeable difference. Transflash I believe is just another name for microSD and are the oldest technology. Newer microSD and SDHC cards can outpace it. Brand wise, I'd recommend Sandisk, as I've been using a 4GB card for 3 years now in two separate phones- very reliable and fast.
Yes I am thinking of getting a 32 GB card. But will this slow down the phone's normal operation? I mean an empty 32 GB card wont make any difference unless it is almost fully filled with files songs and stuff.
