256 GB microSDHC card with adapter

This microSDHC card delivers 256 GB of storage and includes a full-size SD adapter for broad device compatibility. It carries Class 10 and UHS Speed Class U1 ratings for Full HD video capture at 1920x1080. The A1 rating speeds up app loading on smartphones and tablets. Wireless-enabled functionality supports cable-free workflows.

Thermal and power profile in normal use

The card operates without active cooling, so it adds no fan noise to a phone, drone or camera. Solid-state construction eliminates moving parts and keeps power draw minimal during typical photo and video tasks. Rated shockproof, temperature-proof, waterproof and X-ray-proof, it tolerates environmental stress that would stall mechanical media. Everyday transfers stay cool and silent.

Behaviour under sustained write load

Sequential write speeds reach up to 100 MB/s when paired with a quality USB 3.0 reader, while read speeds top out around 60 MB/s. A1 random I/O performance keeps apps responsive during prolonged recording sessions. Real-world throughput depends on the host device and reader; low-quality readers will reduce measured speed. Capacity formats to roughly 28–30 GB per 32 GB increment.

Perguntas sobre este artigo

How do I install the microSD card and adapter so the host device recognises the full 256GB capacity?

Insert the card into the supplied adapter, then into the device slot or a USB 3.0 reader; format it on the host before use and verify with H2testw to confirm the true capacity is approximately 58GB to 60GB.

What ongoing checks or replacement should I plan for this SanDisk microSD card?

The card is shockproof, temperature-proof, waterproof and X-ray-proof, so no routine maintenance is required; replace it only if H2testw reports errors or if sustained write speeds fall below the Class 10 minimum of 10MB/s.

What is the first performance limit I will hit when recording continuous Full HD 1920x1080 video?

The U1 and Class 10 ratings guarantee a minimum sequential write of 10MB/s; once the incoming video bit-rate exceeds that floor, frames will drop even though the card can burst to 100MB/s read.
