Overview

The Sony 256GB UHS-I SDXC card is a Class 10, UHS Speed Class 1 storage medium rated for read speeds up to 70MB/s over the UHS-I single-lane interface, which operates at a maximum bus speed of 104MB/s. In practical terms, the 70MB/s read ceiling means transferring 256GB of full card data to a USB 3.0 card reader takes roughly 60 minutes under ideal conditions — faster than older Class 10 cards that predate UHS-I adoption, but slower than current high-end UHS-I cards rated at 95MB/s or above. The card meets SD Association standards for waterproofing and temperature resistance, which means it can survive the incidental exposure to rain, humidity, and temperature variation that comes with outdoor and travel photography.

This card is sized and rated for photographers and videographers who need reliable high-capacity storage for 1080p video, JPEG burst shooting, or extended travel without swapping cards. The 256GB capacity accommodates thousands of JPEG frames or several hours of 1080p video on a single card, and the UHS-I interface is universally supported in cameras and card readers made within the last decade. The absence of a U3 or V30 rating means it is not the correct choice for cameras that require guaranteed 30MB/s sustained write performance for 4K recording — users with 4K-capable mirrorless or cinema cameras should verify their camera's card speed requirements before purchasing. For the intended 1080p and photography use case, it is a reliable, high-capacity option backed by Sony's component quality standards and supported by the included File Rescue recovery utility.

Pros & Cons

👍 Pros

  • 256GB capacity on a single card reduces the need for mid-shoot card swaps during extended sessions or travel photography.
  • 70MB/s read speed enables fast file transfers to a laptop or card reader, reducing post-shoot ingestion time compared to older Class 10 cards without UHS-I.
  • Waterproof construction and wide operating temperature range make the card suitable for outdoor, travel, and field shooting environments.
  • UHS-I interface is backward compatible with standard SD slots — no hardware upgrade required to use this card.
  • Bundled File Rescue software provides a recovery option for accidentally deleted files without requiring a third-party utility purchase.

👎 Cons

  • Write speed is not explicitly rated beyond the UHS Speed Class 1 (U1) minimum of 10MB/s — this is insufficient data for photographers selecting cards for high-speed burst shooting.
  • 70MB/s read speed is mid-range by current UHS-I standards; newer UHS-I cards reach 95–104MB/s, offering noticeably faster file transfers to a computer.
  • No UHS Speed Class 3 (U3) or Video Speed Class (V30) rating, limiting suitability for cameras that require guaranteed 30MB/s sustained write for 4K video recording.
  • File Rescue software is downloadable rather than bundled — an additional step that requires internet access and is easy to overlook until a recovery situation arises.
  • SDXC format is incompatible with SDHC-only devices, which can catch buyers off guard on older camera bodies.

Frequently Asked Questions

At 70MB/s read and Class 10 / UHS-I Speed Class 1 rating, this card handles sustained 1080p video and moderate burst shooting adequately. For cameras that write RAW files at high frame rates, the effective bottleneck is write speed — Sony does not publish a guaranteed minimum write speed for this specific model beyond the Class 10 floor of 10MB/s. Photographers shooting high-speed sports bursts in RAW should verify their camera's buffer behavior with UHS-I Class 1 cards before committing.
SDXC and SDHC are different specifications. Devices that only support SDHC (up to 32GB) are generally not compatible with SDXC cards without a firmware update. Check your camera's manual for SDXC compatibility before purchasing. Most cameras and card readers made after 2010 support SDXC natively.
The File Rescue software is a downloadable utility (not included on the card itself, due to formatting constraints). It can recover accidentally deleted or corrupted photos and videos from the card. Download access is provided by Sony separately; the software supports common image and video formats.
Yes. Sony specifies that this UHS-I card is waterproof and rated to perform across a wide operating temperature range, consistent with SD Association environmental standards. This makes it suitable for outdoor and field use in variable conditions.
The 70MB/s figure is the maximum read speed. Write speeds are not published for this model beyond the UHS Speed Class 1 (U1) minimum of 10MB/s. In practice, actual write throughput under sustained camera workloads will fall between those two values depending on file type and camera buffer management.
