Card type and capacity

The TOPRAM TR32GSDUHS1 is a 32 GB Secure Digital High-Capacity card rated for UHS Speed Class 1. It targets photographers and video users who need a compact, new storage medium for everyday shooting.

Who it suits and who should look elsewhere

Casual photographers and Full HD video capture fit comfortably within the rated read and write figures. Users recording high-bitrate 4K footage or shooting long continuous bursts will exceed the sustained write capability and should seek faster media.

Capacity and headroom

The 32 GB capacity holds several thousand JPEG images or multiple hours of Full HD video. Sustained write speeds up to 20 MB/s handle standard recording, while read speeds up to 55 MB/s speed up offload; extended 4K sessions will hit the write ceiling.

Questions about this item

Which SDHC-compatible device slot is required for this 32GB card to function?

The card fits any standard SDHC slot in cameras, camcorders, phones, PDAs, MP3 players or tablets that accept Secure Digital High-Capacity media.

What read and write speeds appear when the card is used in a USB 2.0 reader versus a USB 3.0 reader?

In a USB 3.0 reader the card reaches up to 53MB/s read and 18MB/s write; in a USB 2.0 reader it reaches up to 20MB/s read and 15MB/s write.

How can I confirm the card is delivering its rated UHS Speed Class 1 performance after setup?

Run a benchmark such as FDBench or TestMatrix; sustained write should reach 20MB/s and sustained read 55MB/s, matching the UHS Class 1 minimum.
