SD Card write speeds?

[estra]

Hello,

My tablet has the standard SD card slot and I'm just wondering if write speeds are important when using SD cards on tablets. For example:

Amazon.com: SanDisk 32GB SDHC Flash Memory Card (SDSDB-032G-B35): Electronics
or
Amazon.com: SanDisk Extreme 32GB 30MB/s SDHC Flash Memory Card (SDSDX-032G-X46): Electronics

What's the better buy between the two? Am I going to be okay with the normal blue Sandisk SD card or does the 45 mb/s from the Sandisk Extreme actually does something for tablets?

As long as you get a class 4 or higher SD card, you should not have a problem.

The higher the class the faster the transfer of data. I buy class 10 myself.

as Spider said, Class 4 is reasonable, any lower than that and programs (if running off SD) can hang and you will just get annoyed with the time it takes to do things.

I picked up a Pny class 10 16GB card at Staples for $20 last night. It isn't the best, but a pretty good deal for the price.

I use these Newegg.com - ADATA 16GB Class 10 Micro SDHC Flash Card with SD adaptor Model AUSDH16GCL10-RA1

They are cheap and do what I want with them, I mainly run my tablets from them, make three partitions on them 1GB for system, 4GB for data the rest for sdcard.

Those cards are a nice deal. The reviews say that they die after about 6 months of regular use. The Pny has similar problems reported. I am running a Samsung class 10 atm with 24MB/s read & 21MB/s write. (after reading the reviews on the Pny, I decided not to use it for now.)
Thanks to your directions and boot image (and rom) , I am running my tablet from a partitioned card as well.
