Hi can SDHC cards be used with the 405D Local retailer has 4gb for 12 but uts SDHC and not SD
Thanks in advance
 
Cheers m8y
I am off to get some bargains cheers
 
i have 3x4GB SDHC ultra II cards with my 450D no probs
 
thats not cheap!!! 12 quid for 4GB is expensive

visit www.mymemory.co.uk, it's £8 there for the fastest 4gb, and 12.99 for the fastest 8GB.
 
Hi I have learnt something new today on SDHC cards
Check your cameras class?
If you get the higher rating it may only run at the lower speed depending on your firmware, Always scared on this as I messed up a games console once by putting the wrong firmware on it. so make sure you read up on firmware before you take the plunge
Hope this helps
4gb at £13.32p 10mb per second, not bad i thinks, how about you
(update it can be 15mb per sec depending on firmware)
SEE BELOW FOR CLASS stats

SDHC (SD High Capacity)

The latest SD technology, SDHC – with faster data transfer speeds and with larger capacities now available !

Integral SDHC has a high storage capacity (4GB upwards) and fast data transfer so that you can store your digital content such as high-resolution photos, high definition videos and more without the restrictions of memory card size and data write-speeds of the past
SDHC is available in three performance classes, Class 2, 4 and 6, created and defined by the SD Association to help consumers identify speed and performance capabilities/minimum requirements of SDHC cards and the host device. Class is dependent on the write-speed of the card, the higher the “Class”, the faster the memory card
The SD Speed Class Ratings specify a minimum sustained write speed for SDHC Cards (Class 2: 2 MB/s; Class 4: 4 MB/s; Class 6: 6MB/s*)
All Integral memory cards are optimised to work brilliantly in the latest SDHC compatible devices

* Designed for SDHC compatible host devices**
* Larger capacity – 4GB and 8GB now, up to 32GB in the future
* File system has changed from FAT12/16 (used in SD Cards 1GB and below) to FAT 32 (used in SD Cards 2GB and above) to enable the larger capacities
* SDHC memory cards are just as compact and slim as the standard SD card
* SDHC is compliant with the original SD Card CPRM copy protection specifications
* Solid State - No moving parts
* Non-Volatile - Data maintained with no power
* Complete with FREE protective case
* Tested with a wide range of SDHC devices
* 2 year warranty

**N.B. Not all devices support SDHC cards.

To ensure compatibility, look for the SDHC Logo on the product or packaging of your new camera or digital camcorder.
If your digital camera or camcorder displays a Class 6 logo then Integral recommend that you should use a Class 6 SDHC card in the device – Class 2 and Class 4 cards are compatible but your device will run at their slower speed.
Due to SDHC using the latest technology, any digital camera or other device purchased before 2006 will not be compatible with SDHC memory cards.
Please be aware of non-SDHC compliant SD 8GB cards on the market. If these non-compliant SD 8GB cards record data in a SDHC device such as a digital camera then file system incompatibility and data corruption may occur. This can mean that you may actually loose your pictures/video/data. So, to avoid problems, if the SD 8GB card does not have the SDHC logo on it, it is not compliant.
 
10mb does that mean your card is class 10? no sure that exists at the moment
 
well I am dubious about these tin labels...they are well misleading...

mbps and MBps are two different things. one is Bit/s and the other is Byte/s, its all in the capital.


but your card still sounds a bit expensive to me. for the fastest card on a 4gb it should be around £8

On a seperate note CF cards are amazingly fast
 
Cheers Ricky
Now you got me going on CF cards Thankfully my 450D dont take them
Its my bum typing sorry to say, my caps lock has its own mind, diciding when it wants to work

thanks again

Quedash test out the card by loading a 1GB file onto it via XP. must be a card reader that supports the speed. it should be done in 2min40s if its 6speeds and you can do the rest of the maths if its slower than that :)
 
AFAIK class 6 is the highest for SHDC cards, how exactly this ties to the read/write speed Im not sure.
 
Hi Ricky
sorry I dont have a card reader yet
I just load from camera
But I will borrow one tomorrow and test out the speed
Cheers

Hi Craft
Class 6 simply means 6MB per second. class 4 is 4MB amd Class 2 is 2MB
Hope this helps
Cheers
 
speeds are bandwidth. that's the theoretical fastest speed it can achieve if it's a sequential read or a sequential write.

typically on a memory card for camera you are only doing 1 type of operation at a time, but it's not necessarily sequential read, might be multiple read. not entirely sure how the controller works it all out. but a simple large file transfer should tell you the speeds.
 
Getting tech now Ricky, My head hurts so time for sleep
Big test tomorrow hehe:rules:
