Similar to other post, i.e. twin pack of 4GB Class 4 SDHC cards for £10.49, (link below) but worth £1.50 for the upgrade to Class 6 IMO.

I'm waiting for the Micro SDHC's to get cheaper. Want an 8gb one for my Tocco. Although I'm not even sure the phone supports it! lol.

I have a 14.7MP camera which also records in HD - would there be a noticeable difference between class 4 and 6?

I think you will - Class 4 might be able to cope with HD but if you want to use 'burst' or 'continous' shooting it's certainly worth paying the extra £1.50 for class 6.

My daughter has just bought a 7mp camera that can shoot in raw mode - we have a pair on order - I'm sure they'll be overkill but... :thumbsup:

Edit: Class 4 is 4MB/s or 32Mb/s - I think 720p is recorded at between 10-20Mb/s so Class 4 would be plenty fast enough - But I'm guessing a 14.7MP jpeg would be over 4MB in size (RAW will be bigger) so you'll not want to slow your camera down.

I'm going for the Class 6 for faster data transfer from card to computer. I wouldn't expect a huge difference in the camera speed (although I have no experience with HD video) but should be a benefit when transferring a large amount of data to PC etc.

Thanks both of you.

I've had the 8GB and 4GB class 6 card double pack on order from play.com for ages now and they are still out of stock so I'm gonna have to find some elsewhere now.

Ordered one from Play yesterday - class 4 8GB for 10.49 which didn't seem bad. Although 5 quid would obviously be nicer!

Are the older SD cards faster than class 6? For example, the SanDisk Extreme III 2GB SD is 20MB/s?

Exactly, class 6 just demands a minimum of 6MB/s. EVERY remotely ok card is leagues faster even if they don't say it, including the very most basic Sandisks.

I think you're quite wrong - lots of manufacturers claim 20MB/s speeds or whatever quoting peak speeds - the Class rating is for sustained transfer. The sandisk extreme II cards used to be class4 but are now shipping as Class2 even though sandisk still claim the same peak speeds. By your logic Sandisk Extreme II cards aren't even remotely OK;-)

Only if the sustained transfer rate was over 6MB/s.

I have a basic sandisk MicroSD (not an extreme anything). It holds 15MB/Sec constantly without trying.

I don't care what they claim, I've not seen an SD in YEARS that can't comfortably do 6MB/sec.

I don't have them - this is the class rating shown on the Sandisk packaging - i.e the Class rating they've officially been tested at and assigned - if they could justifiably claim the higher class I'm sure they would.

I don't know what testing method they use for the Class ratings - perhaps they aren't using realistic real-world tests.

Sorry I should have been saying Ultra II not Extreme II - See ]this guys blog - I think he's suggesting Sandisk are delibrately underating the cards to make thier new products appear more favourable..

Sorry Dudley - I was a little off-base on this :oops: According to the SDHC wiki

The SD Speed Class Ratings specify the [COLOR="Red"]minimum[/COLOR] write … The SD Speed Class Ratings specify the [COLOR="Red"]minimum[/COLOR] write speeds...

- so it is quite possible that a decent card could way exceed it's class rating depending on how you use it.

Class 6 is the highest transfer speed.

Class 2 is equivalent to the old 13x speed (2Mb/s), Class 4 is equivalent to the old 26x speed (4Mbs), and Class 6 is equivlaent to the old 40x speed or 6Mb a second.

Anything Above this (e.g. 66x/10Mbs, to 300x/45Mb/s are also Class 6 - There's no higher rating, so you could end up with a minumum speed of 6Mb/s or 16Mb/s.

For what it's worth, brilliant price! Great for cheap removable storage.

order status is coming soon - I wonder how long these will take :?
