The Canon EOS 10D has one memory card slot that uses a Compact Flash card that can have a maximum storage capacity of 8GB. If you try to use a CF card with a larger capacity than 8GB the 10D will encounter errors.
Choices of memory cards are limited due to improvements that have moved production to larger capacity cards. With few devices or cameras having an 8GB memory card limit, there is limited demand for that capacity.
Cards with smaller capacities will most likely not be cheaper. The main spec that the price is based on is the transfer speeds of a card. A card with faster read and write speeds will save you minutes of waiting for files to transfer.
My recommendation for the best memory card for the Canon 10D is:
- 30MB/s Read and Write Speed.
- Highest quality card available new.
- The ideal combination of value, performance, and reliability.
Recommended CF Cards
- Up to 50MB/s read speed.
- 20MB/s write speed.
- Supports up to Ultra DMA transfer mode 4.
- 30MB/s read and write speeds.
- High-performance card.
- Type I format.
- Low power consumption.
Memory Card Reader
The UGreen 4-in-1 memory card reader works with four different memory card formats. These include all memory cart formats camera manufacturers make use of in all but the most recent professional-level cameras.
The UGREEN reader connects over USB 3.0. The USB 3.0 transfer speeds will be faster transfer rates than what the Canon 10D can reach using the USB transfer mode.
There are many positive customer reviews for the UGREEN reader, which I agree with. I would recommend it because it has been recognized by all the computers (Windows, Mac, and Linux) I have plugged it into.
The cable prevents card slots from being blocked by other accessories or devices that are being used in another USB or neighboring port.
When I looked for a more compact card reader that would be easier to travel with, I needed to return a couple of orders. I came across the most frequent problem in customer reviews, the card readers were not recognized by my computer.
The ugreen reader can be used with the following card formats:
- CompactFlash Cards
- SD, SDHC, & SDXC Cards (UHS-I supported)
- Memory Stick (MS), MS Pro, MS PRO-HG, & MS XC DUO
- MicroSD, Micro SDHC, & Micro SDXC Cards
Compact Flash Card Types
Compact Flash cards come in two separate physical sizes. The cards are known as Type I or Type II.
What makes the cards different, is their thickness. All other dimensions of the cards are the same.
- Type I - 3.3mm thick
- Type II - 5mm thick
The Type II spec allowed Microdrives to be used with the Canon 10D. A Microdrive was a tiny mechanical harddrive.
Compact Flash cards had small capacities when they were initially released. Microdrives were a solution that allowed for considerably more storage.
Microdrives have not been produced for many years. Due to their mechanical nature, the drives often failed.
Some Compact Flash adapters make use of the Type II spec. The adapters can allow you to use MicroSD or SD cards in a CF slot.
Avoiding Card Read Errors
A common problem with cameras that use Compact Flash cards are pins in the card slot that get damaged. When a pin is bent, you may see any of the following errors:
- Err 02
- Err CF
- No CF
If you want to avoid bent pins, do not force a Compact Flash card into the Canon EOS 10D. The extra room for a Type II card can allow for a CF card to end up being misaligned.
If the Compact Flash card slide into the card reader, take it out and check the alignment of the card. Also, check the card for any damage.
If there is no damage, carefully position the card and try inserting it again.
Now that you know why the SanDisk Ultra 8GB Compact Flash card is the best Canon 10D memory card, you'll be able to pick out the best CF card for any future camera.
