A practical FAQ on the SanDisk Extreme Pro 32GB SDHC UHS-II card: who benefits from 300MB/s, when UHS-I is enough, and how it affects burst shooting and buffer clearing.
Quick answer
Buy the SanDisk Extreme Pro 32GB SDHC UHS-II if your camera has a UHS-II slot and you shoot continuous bursts or high-bitrate video that regularly fills the buffer. If your camera is UHS-I only, the extra speed won't be fully used, so a UHS-I card is the smarter buy.
What 300MB/s actually means on this card
The 300MB/s figure is the card's maximum transfer speed, which mainly affects how fast files move from card to computer during offloading. The catalog also lists shot speeds up to 260MB/s, which is the write speed that matters when the camera is clearing its buffer during burst shooting. Neither number is a guarantee in every camera: real-world performance depends on your camera's card interface, the file sizes you shoot, and whether the slot supports UHS-II.
When UHS-I is the better match
If your camera only has a UHS-I slot, it cannot use the extra UHS-II bandwidth, so you would pay for speed you cannot access. In that case, a quality UHS-I card with enough capacity for your shoots is the more sensible purchase. The same logic applies if you rarely shoot long bursts or large video files: the buffer clears quickly enough with a standard card, and the premium for UHS-II is hard to justify.
The 32GB capacity trade-off
32GB fills quickly with high-resolution raw files or 4K video, so this card suits shorter sessions, backup use, or photographers who offload frequently. If you regularly shoot all-day events or long clips, a larger capacity in the same family may save you from swapping cards mid-shoot. The catalog does not list every compatible camera model, so check your camera's spec sheet for UHS-II support before buying.
Frequently asked questions
- Do I need a UHS-II card for burst shooting?
- Only if your camera has a UHS-II slot and you shoot bursts long enough to hit the buffer. In a UHS-I camera, a UHS-II card runs at UHS-I speeds, so you won't see the full benefit. Check your camera's slot type before paying the UHS-II premium.
- Is 300MB/s the write speed?
- No. 300MB/s is the maximum transfer speed for offloading. The catalog lists shot speeds up to 260MB/s, which is closer to the write speed that matters during continuous shooting.
- Will this card speed up my camera's buffer?
- It can help clear the buffer faster, but only if the camera supports UHS-II and the card is the bottleneck. If your camera's buffer or processor is the limit, a faster card won't change much. Test with your own camera before assuming the card is the limiting factor.
- Is 32GB enough for 4K video?
- It depends on bitrate and clip length, which the catalog does not specify. For long interviews or events, 32GB may be tight; for short clips and stills, it can be workable. Estimate your file sizes for a typical shoot before choosing capacity.
- Does the free postage offer apply?
- Yes, the catalog states all memory cards have free postage when you use coupon code FREEMEMORY in your shopping cart. Add the coupon at checkout to claim free shipping.
