Mini SD Cards

They come in different classes, i'm guessing class 10, that cost a fortune are faster than say 4 or 6. I'm after one for my phone so what class would i need, or would there be any noticeable difference between the classes?, And any reccomendations would be great, cheers andy.

Check the documentation for the phone. It will tell you the max class you can use.

Well downloaded the manual and all it says is, up to 32 gb, mini sd or sdhc card using the fat system, and if you put one in using a different system it will format the card to that system, or words to that effect, still can always ask at a phone shop.

The class is an indication of write speed. If you are likely to be transfering large files off and on the card a lot you will be wanting class 10, they aren't much more expensive. If it has a hd cam you will need a minimum class depending on the cam. My advice is use class 6 or above.

Be warned there are alot of fake cards on ebay, most people don't notice. I was the 25th customer of a guy on ebay, i was the only one that noticed. U told all his other customers to check, they all found they received fake cards and had lost data.

If its a modern phone it will be a MICRO SD, not a MINI SD - they both exist but are different.

Watch out for that

I think stock with my phone was class 4. So class 4 and above is best, obviously the higher the better beyond that!

beabert, yeah had read on here about the ebay fakes so will only get from a proper shop, and yes hd so more speed, must go faster lol.
And cheers SK, did not realise they were different, and yup tis micro, not mini, just thought they were calling them different names, numpty lol.
Will have to try and get a class 10 i reckon, as i will be transfering films every so often, and at the mo when i sync it takes bloody ages, mind you it's only a 8gig in at the mo but it is about a year and a half old, so probobly a class 1 lol.

Ps, how can there possibly be 32 gig of memory on such a small bit of plastic, must be magic :rolleyes:

Class 6 is fine so dont waste cash on a class 10. I use a few class 6 cards in my Nikon D7000 and it is no problem transferring full HD video from the card to the pc so save yourself a few bob.

Mt Experia PLAY came with a 16GB card, I swapped it for a 32GB :p

The class is really only important when recording Video.

Anything Class 4 and above will be fine.

I usually use MemoryBits (http://www.memorybits.co.uk) for cards.

Here are details (http://en.wikipedia.org/wiki/Secure_Digital#Speed_Class_Rating) on the speed thing

Speed Class Rating

The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. The Class number represents a multiple of 8 Mbits/s (1 MB/s), and meets the least sustained write speeds for a card in a fragmented state.[16]

These are the ratings of all currently available cards:[13][23]
Class 2, 2 MB/s
Class 4, 4 MB/s
Class 6, 6 MB/s
Class 10, 10 MB/s

Even though the class ratings are defined by a governing body, like × speed ratings, class speed ratings are quoted by the manufacturers and not verified by any independent evaluation process. In applications that require sustained write throughput, such as video recording, the device may not perform satisfactorily if the SD card's class rating falls below a particular speed. For example, a camcorder that is designed to record to class 6 media may suffer dropouts or corrupted video on slower media. On slower class cards, digital cameras may experience a lag of several seconds between photo-taking, while the camera writes the picture to the card.

Important differences between the Speed Class and the traditional CD-ROM drive speed measurement ("×" speed ratings) are that speed class:[24]
may be queried by the host device;
defines the minimum transfer speed.

Since the class rating is readable by devices, they can issue a warning to the user if the inserted card's reported rating falls below the application's minimum requirement.[24]

On 21 May 2009, Panasonic announced new class 10 SDHC cards, claiming that this new class is "part of SD Card Specification Ver.3.0".[25] Toshiba also announced cards based on the new 3.0 spec.[26]

On 1 June 2010, Pretec announced the new Class-16 HD-video grade SDXC 64GB card at Computex Taipei 2010.[27]
