SDXC vs SDHC: Picking the Right Memory Card Capacity

Quick answer

Choose SDHC when 32GB covers a single shoot and you want to spend less; choose SDXC when you need 256GB for long recording days or high-resolution stills. Both cards here are Class 10 UHS-I, so the real decision is capacity, not speed class.

What actually separates SDHC from SDXC

SDHC and SDXC are capacity and file-system standards, not speed ratings. SDHC tops out at 32GB and uses FAT32 by default; SDXC starts above 32GB and uses exFAT. That matters because some older cameras only accept SDHC, while newer ones handle both. Check your camera manual before buying either format.

The two Hama cards in this comparison share Class 10 UHS-I ratings, so neither has a speed advantage over the other on paper. If your camera needs UHS-I for Full HD video, both meet that requirement. The choice comes down to how much you shoot between offloads.

When 32GB is enough and when it is not

A 32GB card suits a single outing, a backup slot, or a workflow where you transfer files every day. It also keeps the cost low if you prefer several small cards over one large one. The trade-off is more frequent card changes and a higher chance of filling up mid-shoot.

A 256GB card reduces swaps on long days, multi-day trips, or projects with large raw files. The trade-off is that you put more footage on one card, so a lost or corrupted card costs more. Neither card's catalog listing states a V rating or UHS speed class beyond UHS-I, so confirm your camera's requirements if you shoot high-bitrate video.

Capacity is not the same as reliability

A larger card does not automatically make your files safer. The practical rule is to match card size to how often you can offload. If you cannot transfer daily, a 256GB card gives breathing room; if you can, two 32GB cards may serve you better than one large one.

Also consider your card reader and computer. SDXC cards use exFAT, which older operating systems may not read without an update. SDHC cards are more universally compatible, which can matter if you share cards between devices.

Key trade-offs

• Capacity vs. cost: The 32GB SDHC card costs less and suits short shoots, but you will swap cards more often. The 256GB SDXC card costs more upfront and reduces swaps, but concentrates more files on one card. Estimate how many gigabytes one shoot produces before deciding.
• Compatibility vs. headroom: SDHC is accepted by more older cameras and card readers. SDXC requires exFAT support, which most current cameras and computers provide, but check older gear first. Confirm your camera accepts SDXC before buying the 256GB card.
• Speed class vs. capacity: Both cards are Class 10 UHS-I, so neither is faster for video or burst shooting. Do not pay for capacity expecting a speed gain; if you need higher sustained write speeds, look for a card with a stated UHS Speed Class or V rating. Match the speed rating to your camera's recording mode, not just the capacity.
