My 32gb card is showing up on my phone as 29.71GB and a test showed a writing speed of 7.6 mb/s &amp; Reading speed 16.5 MB/S. Is this normal ?

Is it normal, ya sort of :) Not real world results, but it gives you a number for comparison between other devices. Its sort of like car performance and fuel economy results, they are test track and not real world results if that makes any sense. 32gb is the unformatted size, so figure a loss on average of about 74 megabytes (MB) per GB for formatting, basically 32 x 74mb, is about 2.368 gigs, and 2.368 subtracted from 32 = 29.632 but close enough to your 29.71GB number. It may vary slightly on different devices like sticks, drives, etc, depending on what they need for overhead. As far as the speed tests, that really depends on the type of file you are reading or writing. Tiny files in short bursts will give you a different result than reading or writing a 5 or 10gb file. I think the stated 40 mb/s speed is an average of whatever mixture they test on these devices. The chances of hitting that speed is probably not going to happen. What you seem to be averaging is about 1 meg a second write and 2 megs a second read speed, so a 10 meg file would take 10 seconds to write and 5 seconds to read with the data that you used for testing. Hopefully that helps.

http://forums.sandisk.com/t5/Mobile-memory-professional-cards/No-difference-between-Mobile-Ultra-and-Ultra/m-p/289540/highlight/true#M1911 there is no difference at all both at class 10 both read at 40mb/s it was a marketing ploy. Personally I went with mobile ultra for my s4 and ultra plus for all tablets computers and other devices like cameras etc. The link will explain it sir.

The formatted capacity should be showing 29.6GB with exFAT. But I was able to measure 47MB/s read and 13MB/s write, in a USB 3.0 memory card reader. It is possible that your card reader is not UHS-1 capable.

I have a used this drive with a 64 GB card and 128GB there has been no trouble with it being read and the speed is the same as the 32 GB cards I have used with the Transcend Information USB 3.0. Hope this helps out.

I get card error when tring to format my 32gb, and card too small error when I have a 2gb SD card installed, is this thing junk?

No. The card is manufactured by SanDisk. Probably it was a mistake of advertisement. I have two of them on both my Samsung devices and they are working flawlessly. Maybe it is because they pair really well with Samsung products.

I use a 32gb get the fastest card (Class Number) you can find. This thing loads slow because it uses a clumsy Apple Quicktime format.

http://www.sandisk.com/products/memory-cards/sd/. Yes the read/write speed is 95 MB/s compared to 80/60.

I intend to use a 32gb card. Does that mean that it will not use the built in 8gb? Therefore I am paying extra for nothing?

This thing is very fast never had a read issue. I think it would be more dependent on the speed class of the SD card. The USB speed on this thing blows my mind!

It could be a memory issue. I got the lower 48 downloaded after inserted a 2 gig (I think that was the size) MicroSD card. Try it.

there is 8 gigabytes on board and then there is also he micro SD card slot which can take my card up to 32 gigabytes. The phone actually came with a 32 gigabyte card originally when you bought it new. Hope that helps.

The writing speed is said to be 190 mb/s and read to be 245mb/s. Looking at reviews this seamed to perform very well and close to the statement. I did a lot of research and found this to be the fastest at the time without spending over $150. I bought this one for my bro in law and I have the 32gb and both are really fast! I can vouch for the 32gb going up to 145 mb/s write I saw it when transferring a larger amount of pictures once. However the 64 is supposed to out perform the 32, either way tho, I doubt you will be disappointed. Evey person that has one of these that ik personally and online are more than satisfied!

I have a 128 gb card in mine mine. I have had no issues with the card at all. I transfer a lot of music and video files frequently..never had a single issue with card reader.

I believe the wrote speed is up to 90MB/s* and writes up to 60MB/s. Hope this helps.

Up to 90MB/s read speed, 50MB/s write speed. That's what it says in the ad and it may be right. All I know is it the fastest and smoothest card I own. I have 2 12.2 Samsung Pro Tablets and I purchased one for each device. Very fast, that's all I can say. The Samsung EVO is a good card also. I have those in our smart phones. Both cards or fast and reliable. There is also another Samsung PRO card that is black and has speeds up to 70 MB/s. DO NOT buy that one. I tried one, it failed, was sent another, it failed, and after the 3rd one failed, my money was returned.
