what is class 4 sdhc

I chose this class for storing additional movies to bring on vacation & although it's a little slow to load the chip, it's still plenty fast enough to play them without buffering on my tablet.

Hello Austin: Usually the capacity indicated in GB (there are almost no MB and still not go to the market to come to a TB or exceeded); "Class" instead what it does is indicate the data transfer speed in megabytes per second (MB / s), this is because the technology is so demanding, mainly photographic machines. So classes are related as follows: Class 2: 2 MB / s Class 4: 4 MB / s Class 6: 6 MB / s Class 10: 10 MB / s Hope I have clarified its meaning.

Gabriel essentially explains it correctly. The number represents the speed of the memory, the higher the better, all other things considered. It matters the most in applications that involve the fastest xfer possible, such as photography and video, which create huge files which need to be xferred quickly to the chip so the device can go on to the next pic or video frame.

Do not listen to Glussseppe G. about Class 10 MicroSD cards.. I am using the new SanDisk Ultra 32GB MicroSDHC Class 10/UHS-! at 80MB/s and it just works find.. Also the class 10 cards will work on any class 4 devices. You just can not use lower then 4 class cards like class 2...

A Class 6 SDHC card (which I intend to buy in 32GB for my own TX7 when the price is right) would be faster than a Memory Stick Pro Duo Mark2 and probably even a faster than a Sony Memory Stick PRO-HG Duo (since these have been around for years). My TX7 came with an instruction manual which suggests that Mark2 is sufficient; this would correspond to about a Class 4, but I'd go with a Class 6 just to be safe. In no way can a TX7 (or any similar device) come close to taking advantage of a Class 10 SDHC.Hope this helps.

I bought a 16GB Micro SDHC Memory card from Sandisk class 4, which is fine for me.

Is that "should" a definite yes?Also, can I use a "Class 6" sdhc card, or will it only accept a "Class 4". Thanks.

I did not find it on PNY's website here is the link tho, if you email them they may be able to send out a PDF or something...http://www3.pny.com/4GB-Performance-SDHC-Class-4-P2113C476.aspx I know it looks different than the one they show online, but the size and class are the same so they should be very close

the "Class" represents the minimum transfer rate you should see with these cards. Class 4 = 4MB/s Class 6 = 6MB/s Class 10 = 10MB/s There is an informative page on the kingston site at the following link: http://www.kingston.com/flash/sdhc.asp

the higher the class the better, but from sd specs alone, technically a class 4 at 4 megs/second should be sufficient since it can write atleast 3.6 gigs in 15 minutes, when you only need 1 gig per 15 minutes for this camera. I would suggest getting atleast a class 4 just to be on the safe side. (although a class 2 will be 1.8 gigs per 15 minutes), so you need a card that can write at fast speeds.

confusion around this is due to the fact that early versions of the camera had problems with some Sandisk class 10 cards, and the Mobius manual says class 4 is all you need, along with a warning about using a class 10 with early firmware versions. But that was with firmware versions in the low 1.x. They're at 2.37 as of this writing, and i have 2 cameras that use class 10 cards (1 a sony, 1 a sandisk) with no issues.

Check out Wikipedia's entry on it: http://en.wikipedia.org/wiki/Secure_Digital_card#SDHC SDHC normally only works on devices that specifically state that they have support for it. So it really depends on what you are buying it for. To ensure compatibility, I would bet on the regular microSD card. That being said, if you want the 4gb or 8gb sizes, you would need the SDHC, but make sure you have a compatible device.

I am using a PNY 4 GB SDHC card. They are very inexpensive. About $5 to $10.

You know.... I bought this unit and had to return it 3 times because I was using a 32GB class 10 - then after contacting e-prance, they said to use a class 4 !!! I know that a class 4 is faster, but it refused to work. The only good thing is that class 4 are cheaper! I have 3 of these cameras, 1 with GPS and 2 w/o. I love them!

I'm going to stand behind class 2. I purchased a class 6 and class 4 from Sandisk and they blast 2gb file transfers over to the cards but this one is well below class 4. Good card and holds files good but definitely slower.

The Coolpix P520 supports SDHC cards up to 32GB, and SDXC cards up to 128GB. It requires class 6 or higher. I am using a SanDisk Extreme SDHC UHS-1 (class 10) 32GB cards rated at 45mb/sec read/write speeds with excellent results. This is an awesome camera.

The camera is capable of using all 3 types of cards. SDHC and SDXC give you the largest capacities. SD cards max out at 4 gigs. SDHC max out at 32 gigs and SDXC can go up to 2 Terabytes but typical cards are 64 to 128 gigs and they are $$$$. I bought a 16 gig SDHC class 10 for my camera. Each image at full resolution is about 5 to 7 MB in size. A 4 minute movie in full HD is about 140 MB in size. Class 10 is the fastest class and can read/write fast enough to keep up with HD video recording without lag. they are all flash memory type cards.
