Product Identity

The Transcend TS64GSDC300S is a 64GB SDXC UHS-I memory card rated Class 10 and V10. It targets photographers and videographers using UHS-I cameras or camcorders who need reliable storage for everyday shooting.

Who It Suits

This card suits users recording 4K video at bitrates the V10 rating supports and capturing high-resolution stills. It is not for workflows that demand sustained write speeds beyond 20MB/s or UHS-II bus performance.

Deciding Specification

The card delivers up to 100MB/s read and 20MB/s write speeds under the UHS-I interface. That write ceiling determines whether the card can keep pace with your camera's required video bitrate.

Questions about this item

Will the 64 GB capacity need any maintenance or replacement over time?

The card is a solid-state device with no moving parts, so no scheduled maintenance is required; it only needs replacement if the NAND wears out after very heavy write cycles.

What speed limit appears first during sustained 4K recording?

Continuous write speed tops out at 20 MB/s, which is the bottleneck for long 4K captures.

How much heat or power draw should I expect when the card runs all day?

Typical SD cards draw well under 1 W and stay near ambient temperature even during continuous read or write activity.
