I bought 2 cards at the same day. One Samsung for my S4 and one Sandisk for my friend's S3. After I got them I ran many tests with pc (crystal disk mark) , phone (S4, sd tools) and a manual test of transferring 2 Gb folder contains small JPEG pics).

Samsung won in every tests. It was way faster in both sequential and random speeds than sandisk. Samsung was always exceeding the class requirements but sandisk disappointed many times.

Here are the results

Samsung 16 GB MicroSD Plus Class 10

I am using this product with my Sony XPERIA Neo V since last 15 days and have no issues by any means what so ever.
Can give u a write speed up to 9Mb/sec for large files and on average 7Mb/sec for any kind of multiple files where as SDHC class 4 card can only give u a max of 5Mb/sec.
You will sure notice a significant performance boost up for media contents and opening up large files but if you are using it for game play boost up, so you are wrong my friends because game performance is dedica...

Its very rare that I am not able to find a flaw with a gadget.

PROS
This card is so tiny yet stores so much with high speed

1) Very fast speed, like blazing fast. Writing speed gets upto 9Mb/s (so much better thatn USB 2.0 pendrives). Reading speed is alot faster. I keep hd movies in it instead of hard drive, and they play back smoothly in this pc.

2) The free micro to SD card adapter is just wonderful

3) The card didn't get slow after 3 months of usage (this is a good point, if not bad)...

No need to say the service is amazing as always. For that, thanks flipkart.
For power an speed hungry devices like samsung galaxy S2, Xperia arc, neo etc. who are equipped with the HD camera above 5MP, great CPU and GPU u need the compatible memory card. Because it acts like HDD of your device. It is irony that not a single device is pre-equipped with fast Memory Card.
I replaced the Memory card and experienced the difference in the speed and response.
MORAL --- Card is worth to be replacing ...

This is a very good product.

Benchmark Result :
Write Speed: 10.5 MB/s
Read Speed: 11.3 MB/s
(Power of Class 10)

14.83 GB is the memory which I got in it.
The adapter given with it is very useful.

This is my first online shopping. Delivery was not so fast as I thought but still nice.

You know this site is growing on me every day. The service and quality of the team to do what they are doing to their invisible customers is just mind-boggling. Haven't felt at peace after placing an order with any other online giant. Product description and assurances are met with such ease and makes it that much more easier for the customers to go back to order more. My only suggestion will be for the administrators to add multiple pictures of the product (or multiple views) to have a bette...

I am using this memory card as an expandable memory to my Sony Xperia ZL and my review is its Excellent memory card for this Android Smartphone. Also i think i would work great with any smartphone. My data in card include Videos, Pictures, Music, Documents which can be accessed with less time. No jitters in Video playback especially FULL HD videos. Also high-quality documents as well. Comparison of speed would be: Write: avg 10~15Mbps and Read:20~30Mbps.

cons: Sometime memory cad wont get l...

i have researched on the net and decide between samsung class6 and this one. samsung product was out of stock so i have to settle for this. this is not fast enough. speed like class6. i get 5-7mb/s. but the samsung class6 card is far better than this. it gives around 10mb/s. my friend have this. so go for samsung class6 between these.

Got this the other day from Flipkart. Surprising though I felt the item should have reached my by end of day since I had ordered the previous night - but it remained in a sort facility just 20kms away from my house since morning the entire day. Got it the next day.

On the picture they have shown a red adapter and also said android app included - but I got a black adapter and no app - the memory card was empty.

Putting aside these discrepancies, Im happy with the purchase.
The pricing is ...

I am using this memory card with my Sony Ericsson Neo V. It works perfectly fine without any issues.
While this card is certainly fast in reading but the write speeds I get have been 7 mbps average.
This is certainly faster than the stock memory cards that come with phones or the regular ones we buy from stores.
Since this is a class 6 card minimum write speed of 6 mbps is expected.
This card would improve your experience while copying large files however the phone usage experience wont be n...
