Kingston 32gb speed compare from Newegg
 

Picked up the Kingston class 4 32gb microSD card from Newegg and tried it in the EVO, initially it would not recognize the card until I formatted it. It was already FAT32 but I formatted FAT32, 32k, and it then recognized the card.

I then copied everything over from my Sandisk 16gb card and did some speed tests with Crystaldiskmark, here are the results:

So you can see the speed difference between a Sandisk Class 2 and a Kingston class 4, the Sandisk did much better than the Kingston, but since I got the Kingston for $86, I don't really care, it is working fine, and the USB adapter is pretty nice too.

hmm i wonder how it compares to the 32GB class 2 Sandisk alot of us got on sale from verizon

Re: Kingston 32gb speed compare from Newegg
 

Don't quote me on this, but doesn't the class make a difference when xfering large files and or when the card starts getting full?

I don't think it would be fair to compare a card using a small sampling and or a small files test.

No the class rating is supposed to be the minimum transfer rate in megabytes. SO the class 4 should always be faster than a class 2.

Re: Kingston 32gb speed compare from Newegg
 

incorrect, it means the class for has to be at least 4 megabits a second and the class 2 needs to be at least 2 megabits a second, that doesn't say anything about top end. The class is only related to the MINIMUM speed.

Not trying to be smart but why not buy one of these:

â„¢SanDiskâ„¢ Micro SD Memory SDHC Card 32 GB G TF Flash - eBay (item 220699064617 end time Nov-28-10 22:49:40 PST)

I know people have reservations about buying stuff from China off ebay, but I've had mostly positive experiences. I'm not into all the speed testing mentioned above, I just want a card that can hold a lot of stuff. I bought a 16gb card similar to the one above about a year an a half ago and it works fine for my purposes. But I have a lot of music and pictures and ROM backups so its getting full and I think I'll just order this. For $20 shipped, I think its worth a shot.

BC I'm pretty sure that will not come with 32 gigs. Ill say if your lucky you'll get around 8 gigs.

Lets be real. Its not like the batteries where 90% of people won't check the actual amount of juice it has. If they sold 8 gig cards advertised as 32gig cards, their feedback would be atrocious.

Like I said, I bought a 16gb one from a similar vendor last year and it came with 16gigs
