Five 256 GB microSDXC cards rated V30 for 30 MB/s sustained writes and up to 95 MB/s reads with SD adapters included

  • TypemicroSDXC
  • V30 rating guarantees 30 MB/s minimum write for 4K video
  • UHS-I interface delivers up to 95 MB/s read for quick file access
  • 256 GB capacity per card stores hours of high-resolution footage
  • Shockproof, waterproof, temperature-proof and X-ray-proof construction survives harsh environments
  • Five cards with SD adapters included for use in microSD and full-size SD slots

Ready-to-use 5-card bundle

This pack delivers five Transcend 300S microSDXC cards, each with 256GB capacity, plus an SD adapter per card. They target photographers, drone pilots and mobile users who need multiple reliable cards for continuous shooting or extended field work without swapping media.

Adapters extend device reach

Every card ships with a full-size SD adapter, letting you move the same microSDXC media between action cameras, drones, smartphones and laptop SD slots. The adapters add no speed penalty; they simply adapt the physical form factor so one card works across microSDXC and standard SD devices.

Check host limits before ordering

Your device must accept microSDXC cards and the UHS-I bus to reach the quoted 95 MB/s read and 40 MB/s write peaks. Older hosts that only support Class 10 or U1 will cap sustained writes at 10 MB/s. Verify the slot type and bus support in your equipment specifications.

Questions about this item

Will the five included microSDXC cards need periodic reformatting or replacement after heavy write cycles?

The cards are rated V30 and U3, guaranteeing 30 MB/s minimum write speed; they are shockproof, waterproof, temperature-proof and X-ray-proof, so no scheduled maintenance or replacement interval is required.

What is the first performance ceiling reached during continuous 4K or Full HD recording?

Sustained write speed maxes out at 40 MB/s, while the V30/U3 floor stays at 30 MB/s, so the 40 MB/s ceiling appears before the card drops to the 10 MB/s U1/Class 10 fallback.

How much heat or power draw should I expect when all five cards record video all day?

MicroSD cards draw very little power and generate negligible heat; the spec lists read up to 95 MB/s and write up to 40 MB/s with no active cooling needed.
