Class 4 - 16GB Micro SDHC Card now in UK

OK, 7dayshop are selling the following for £38.99 in the UK
Micro SD High Capacity (MICROSD-HC) Memory Card - 16GB Class 4 (118x) - Dane-Elec
Will it make any difference to the X1 if its a class 2 card or a class 4 card?

The classes defines the writingspeed of a memory card. A class 2 Card can write 2 MB, class 4 4MB/second. The real writing speed is much different. My 16GB Memorycard (Class2) is much faster than my 8GB Card (Class 4).

Yeah that true i have reliaze that after i have already buy a dan-elec MicroSd of 4Gb and it is slower in writing than my old one MicroSD 8Gb Sandisk (OEM with my xperia)...
So i recommend you to buy a MicroSD Sandisk this brand is faster and more quality...
And if sonyericsson choose it..Is for something isn' t it?
Also Kingston are good but Dan-Elec or Duracell (Are the same)
Are the worst i think....
Very slow.............

brand makes a difference.
I have a 16G sandisk class 2, althoguh I did not do any benchmarking, it doesnt feel any slower than my previous 8G sandisk class 4 card.
You won't see a difference if you don't do continuous photo shooting or copy big files from your desktop to your card anyway. I say for the purpose of the card (i.e. used in mobile devices) a class 2 is sufficient but I would still recommend getting from reliable brand like sandisk.

SD card speeds?

What speeds should I be getting?
I bought a sandisk 16gb off Ebay. Figured it was safe being "sandisk" and all.
I am getting about:
6mb/s write
19mb/s read
Saw someone pose they got 3 write and 130 read...
can this also be ROM related? They were on magnolia I am on CM7.

It sounds like a reasonable number, I have an older SD card that writes at about 3.5mB/s.

Sounds like a standard Class 2 memory card. Check your uSD card, does it have a little number inside of a circle? If it doesn't it's more than likely a class 2 card.
They categorize most flash-based memory cards by "class" now, the higher the class, the faster the read/write speeds. They have them in multiples of 2's. I have a class 6 8GB microSD from Transcend that I use for my Nook Color and I get on average around 11.5MB/s write speed.

Definitely atleast a class 4. Class 4 is 4Mb/s read speed. The write speed is irrelevant.
I have a class 4 Sandisk as well and it reads at just over 6Mb/s. Not sure on write speed. It was definitely faster than 19Mb/s though. Did you test it using h2test to make sure its a legit card?

[Q] Which SD Card to go with out of these 2?

Hi all,
I've currently been using a 16GB Sandisk Class 4 MicroSD in my Note, and that's filling up, and I'm planning to switch to a 32GB card.
BUT, there's 2 I'm stuck against choosing between.
This one is a 32GB Class 4 card by SanDisk:

But this one is a 32GB Class 10 card by Play.com:
http://www.play.com/Mobiles/Mobile/4-/21619964/0/Play-com-32GB-Micro-SD-SDHC-Memory-Card-Class-10/ListingDetails.html?searchtype=allproducts&searchSource=1&searchfilters=ae63{Play.com}+&urlrefer=search
Which should I go for?

If you want more speed: Class 10
If you want more money: Class 4

I used a 32gb class 10 previously and now the 64gb SanDisk class 6.
While I did like the speed and filling up the new one took it's time, I do prefer volume over speed.
The 64gb gives me so few worries over space, and once my "permanent" media was on it I am in gb-heaven.
But then, to me the space was the priority.
If you have the need for speed, a fast 32 may fit you better, or you can wait until 64 gets fast.
Also keep in mind that you can buy a fast 32, a 2 dollar usb otg cable on Amazon and a big thumb drive for less than the price of a 64. But that is a clunky solution.
I prefer the big card.

Why dont yo go for a 32 GB Sandisk Ultra (Class 6) Memory card. It has a good performance.
If in any case you need to buy a class 10 card go for transcend/kingston or even Samsung

i suggest you to buy patriot class 10

[Q] MicroSDHC

is our galaxy 3 is compatible for microsd 2.0? does it support MicroSDHC. and if yes does that make any difference.
I read that HC stands for high capacity even transfer speed is more..so wanted to buy 4 gb class 6 MicroSDHC.. is it a good option :silly:

I have 8 class 8GB microsdhc card and works fine. No problems. Writing speed is aprox. 4,2 MB/s if it helps.

I have 8GB class 6 microsdhc and it works fine.

I had the same question...but I directly approached the Samsung guys...they told me that for sg3 microsdhc cards up to class 6 are supported. Above classes will work but not at their optimal speed.

I got 16GB class 4 works awsm.....

microSD speed 4 Tab S

what is the speed of Tab S card slot?
I'm going to buy a microSD card and I don't know what speed should I take:
30, 50, 80 or 90 MB/s?
I don't care how fast I can copy files from PC. I just wonder what is the maximum speed of read/write by Tab S?

I dont unfortunatley have technical speeds of how quick it copies but i found that mine. Could happily copy 2GB files from internal to my UHS1 64GB sd card from samsung pretty quickly, within 1 minute.

So it is about 33MB/s. Class 10 is not enough.
So minimum Sandisk extreme?
http://www.sandisk.com/products/memory-cards/microsd/

I guess depends if you can get a UHS-2 or 3 that a tab s can make the most of? Just used A1 SD Bench and got 30 MB/s write and 13MB/s read (edit. Other way round). It is a UHS-1 samsung micro sd card. Possibly a samsung EVO or SanDisk extreme.

I have the Lexar 64gb 600x micro sdxc class 10 UHS-I 90mb/s, I have had it about 4 months now and it was previously in my Samsung Galaxy S4. I have never met transfer speeds as fast on any other microsd I have used before, nor have I been met with such stability. I have one of these cards in my Samsung Galaxy Tab S for storing any media (books, music and movies) and haven't had any issues still. I also have another in my Samsung Galaxy Note 4 I which I play music from every single day.
As I said, I have had the card for a few months now, and I have used it in 3 different devices, all with outstanding performance. The origin SanDisk microsd cards I purchase (2x 32Gb micro sdhc ultra) I had to return 3 times before I had a reasonably stable working product. I am not dissing SanDisk nor promoting Lexar. I just want to share the experiences I have had recently.
I hope this helps. Message me if anyone has a question.

Can you make a speed test in A1 SD Bench and post results (Tab S)?

A1 SD test results.
The first picture is the test results from my lexar 64gb sdxc 600x UHS-I
The second picture is a comparison using SanDisk Ultra 32gb sdhc.
Testing device is the Samsung Galaxy Tab S (SM-T700).
