Find the right SD card speed for your Sony α7 IV. We explain UHS-II, V60, and V90 ratings so you can match card performance to your shooting style.
Quick answer
For most Sony α7 IV owners, a UHS-II V60 card like the Sony SDXC 128GB V60 TOUGH provides the best balance of speed and value. If you shoot 4K 60p All-Intra video or rapid bursts, step up to a V90 card.
Why card speed matters for the α7 IV
The Sony α7 IV records 33-megapixel stills and 4K video up to 60p in All-Intra and XAVC S-I formats. A slow card can cause the buffer to fill quickly or stop recording mid-clip. Choosing the right speed class ensures your camera performs as intended.
UHS-II vs UHS-I: a real difference
The α7 IV has two UHS-II-compatible slots. UHS-II cards have an extra row of pins that nearly double the theoretical transfer speed compared to UHS-I. While a UHS-I card works, it will bottleneck burst depth and high-bitrate video. Stick with UHS-II for the camera's full potential.
Decision rules: pick your card speed
- Still photography (JPEG or compressed RAW): A UHS-II V60 card (e.g., Sony SDXC 128GB V60) clears the buffer fast enough for casual to moderate burst shooting. You get reliable write speeds without paying the V90 premium.
- 4K video up to 60p (XAVC S / XAVC HS): V60 is the minimum for 4K 60p at 200 Mbps. The Sony SDXC 128GB V60 handles these bitrates without dropping frames. Use a V90 card if you record 4K 60p All-Intra (600 Mbps) or ProRes externally. Check your video mode: if the camera shows a slow-card warning, upgrade to V90.
- Uncompressed RAW bursts or extended All-Intra video: A V90 card (90 MB/s minimum sustained write) keeps the buffer from stalling during long 10 fps RAW sequences and prevents recording interruptions at the highest bitrates. V90 is not needed for most α7 IV users; reserve it for uncompressed RAW shooters and heavy video workflows.
