Don't worry now for System Space to save Video, Audio and Other files that you want keep always with you. Here is the solution. Opt for Samsung 64 GB Class 10 Memory card. This one gives you fast transfer of any file type. Water proof ans x-ray proof. I Just love this Memory Card. I'm using in Samsung Galaxy Note 3. My phone works faster. ?

Samsung SD cardI bought this product for my Samsung phoneI personally wanted a high speed SD card because I had been using a class 4 sd card and its not so fast and doesn't store data quickly. As my phone has 16 MP camera and I wanted my pictures to get directly transferred to my SD car it's was not possible before .But now I bought Samsung EVO class 10 64gb card I can directly store the images taken by my phone to the SD card ,and it works like a charm ,Would really recommend this productBecause of the transfer Speed whichI personally got was read about 100MbpsAnd weight about 48 MBpsVeru Happy with the product

I too received the card without arrow signs. And due to sheep walk i orde4ed replacement. However, after doing RnD and thinking rationaly i thought to go for benchmark test...what i found is also written on samsung's official website that..design can chage but not the performance. However untill unless they write their that non-arrow SDS are also genuine. No body should take the risks.

Description could have been better. After purchased it I came to know for mobile we require SDHC instead of SDXC. Most of the mobile don't support sdxc card but somehow I was able to change file formatting system to FAT 32. Though it is technical but I succeeded. Successfully working in my redmi note 4g. It is advisable to Amazon team if there are some technical points which are associated with the product don't forget to mention it. Speed is good. I recommend it.

I have received this card yesterday and when I was doing the speed test , at any time I was not able even close to 20 MB/s (both read or write) even for large files. Also when I tried to register product on Samsung support site, It declined to identify the serial number, then I noticed that Samsung India imported it and pasted an additional sticker, when pulled that sticker , I have noticed another S.No and Model code which registered successfully on site but to my surprize it was showing that this product is already out of warranty. So it's clear that Samsung India is dumping their old stock which they were not able to sell in other countries. Earlies I was using SDisk class 4, 8 GB card and that too was giving upto 12 MB/s during read and 6-8 MB/s during write. So can say this is just OK OK product as there is no way that you will be able to get UHS-1 speed on your existing mobile / tablet.

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 Crystal Disk Mark 3.0.2 5 X 50 MB Sequential Read : 20.03 MB/s Sequential Write : 16.48 MB/s Random Read 512KB : 19.92 MB/s Random Write 512KB : 15.65 MB/s Random Read 4KB (QD=1) : 5.348 MB/s Random Write 4KB (QD=1) : 2.357 MB/s Random Read 4KB (QD=32) : 6.146 MB/s Random Write 4KB (QD=32) : 2.449 MB/s SanDisk SDSDQUA-016G-U46A 16 GB Ultra Class 10 UHS 1 Crystal Disk Mark 3.0.2 5 X 50 MB Sequential Read : 22.62 MB/s Sequential Write : 10.85 MB/s Random Read 512KB : 22.24 MB/s Random Write 512KB : 2.383 MB/s Random Read 4KB (QD=1) : 4.159 MB/s Random Write 4KB (QD=1) : 0.536 MB/s Random Read 4KB (QD=32) : 4.190 MB/s Random Write 4KB (QD=32) : 0.592 MB/s Results from Phone (S4, SD tools) Samsung 16 GB MicroSD Plus Class 10 Write Speed: 21.9 MB/s Read Speed: 37.3 MB/s SanDisk SDSDQUA-016G-U46A 16 GB Ultra Class 10 UHS 1 Write Speed: 8.4 MB/s Read Speed: 31.1 MB/s So it seems Samsung plus class is better for both app and media performance than Sandisk Ultra. So I recommend it over sandisk.

It's really better than Sandisk and Sony class 10 memory cards. I had bought three 16 gb sd cards of class 10 and samsung wins the competition in every race the writing speed of samsung sd was 11.5 mbps , while sandisk and sony were only able to get 9.2 and 9.8 mbps respectively (via sd tools and also transfered a movie of 1gb from my ultrabook) For reading speeds all managed more or less the same but Samsung performed a bit faster. priority order - Samsung> Sony> SanDisk so guys if u r planning to buy a sd card within 1k samsung should be your choice also beacuse it comes with a 10 year warranty , also take a look at sd pro which is costly but i think sd plus is best for your needs . Using it in my Xperia. I don't like the plastic samsung phones but it's world's no. 1 company in making silicon chip. what I hate is it doesn't comes with adapter.

Flipkart service, as efficient as always. Product, decent but I'm just a tad disappointed. Reason: I've 7 Sandisk extreme 8gb, 16gb and 32 gb SDHC cards rated at 20mb/s 30mb/s and 45mb/s which I use for my DSLR and general use.All rated as Class 10 devices. All of them give similar test results in crystal disk mark as compared to this particular samsung cards results.(test results for 16gb Samsung plus card given below) Practically, transferring data I get about 15-21 mb/s write speed for all of the Sandisk cards. Even despite their differently claimed speeds,I guess, all of them are identical and the speeds written are a marketing gimmick. Transferring large files is a breeze compared to the other class 2, class 4 and 6 cards I have. On this 16 GB samsung plus micro SDHC UHS-I card, practically i get about 9-10mb/s write speed and at times 10-13mb/s. So i must say its a little slower. The above mentioned speeds and the Crystal diskmark test result is only possible when card is inserted into the laptops memory card slot via micro sd adapter. While using a card reader in usb slot the speed is very much slower of course. Like 3mb/s write speed. The test results for this particular 16 GB samsung card are below: ----------------------------------------------------------------------- CrystalDiskMark 3.0.2 x64 (C) 2007-2013 hiyohiyo ----------------------------------------------------------------------- * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 19.558 MB/s Sequential Write : 14.790 MB/s Random Read 512KB : 19.376 MB/s Random Write 512KB : 14.887 MB/s Random Read 4KB (QD=1) : 4.371 MB/s [ 1067.2 IOPS] Random Write 4KB (QD=1) : 2.399 MB/s [ 585.8 IOPS] Random Read 4KB (QD=32) : 5.410 MB/s [ 1320.8 IOPS] Random Write 4KB (QD=32) : 2.396 MB/s [ 584.9 IOPS] Test : 50 MB [P: 22.2% (3.3/14.6 GB)] (x5) Date : 2013/10/08 19:00:28 OS : Windows 7 Ultimate Edition [6.1 Build 7600] (x64) However tested with different parameters on DiskMark it reveals its true colors: ----------------------------------------------------------------------- CrystalDiskMark 3.0.2 x64 (C) 2007-2013 hiyohiyo ----------------------------------------------------------------------- * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 19.362 MB/s Sequential Write : 7.939 MB/s Test : 1000 MB [P: 24.6% (3.6/14.6 GB)] (x1) Date : 2013/10/08 20:25:08 OS : Windows 7 Ultimate Edition [6.1 Build 7600] (x64) The sandisk cards give read and write results close to 20 mb/s. Tested using an app (A1 SD Bench) on the samsung galaxy s duos the results are: Read: 11.57mb/s Write: 9.9mb/s This is closer to the cards real life performance. I had read a review given by another gentleman on flipkart showing similar results for crystal diskmark. Appreciate the trouble he went through to write a detailed review. Hence, I went for it. Over all I had expected to get about 15-20mb/s practical write speeds which would have made me happy. 9-13 mb/s not so happy. Note: The sandisk extreme cards are higher priced than this card and they are not micro sd but SDHC cards. I'd have given 5 stars it the speed had been a little higher as I'd expected. Verdict: A decent enough card at the price. Could have been a little faster.

The card is excellent. I transferred about 3 gb of data to the card on my xperia z1 and it took about 3 minutes, ie, about 17 mbps write speed. Also, no lag was observed and the phone operation is fluid like always. I suggest you go for this card without any hesitation. Good job Samsung :) Now for flipkart, have a look on the pricing. I don't know if it is a sales strategy or what, but misguiding you customers is bad, whatever the strategy. As of today, the price of this memory card is mentioned as Rs. 4999, with a discount of 49% @ Rs. 2500. Now, when I got the card, on the packaging, it says that the MRP OF THE CARD IS RS. 3499 AND NOT Rs. 4999. So, is Flipkart is pricing the products ABOVE the MRP, and then enticing us to buy them, saying that the discount is 50%, where in reality, it is just 29%. I'm not raging about it, but Flipkart should be honest about pricing or else its customers will lose their faith in Flipkart.

For everybody who is commenting on the speeds of this memory card, any uhs enabled card for the matter, for getting the speeds given on the data sheet you need a mobile or device which has UHS interface (which mostly comes with only flagship phones). its backward compatible so it'll work on normal devices also but with low transfer rates. Its like plunging in a usb 3.0 pendrive on a usb 2.0 port. so check if your device is compatible before blaming the card for its low transfer rates.
