The M303's speed rating supports 4K Ultra HD video recording, a prerequisite for the latest action cameras, video recorders, and drones. Smartphones compatible with the microSDXC specification will benefit from the M303's ability to record high-resolution video and images at high speed. With a Video Speed Class 30 (V30) rating, the M303 provides a minimum data transfer rate of 30MB/s with a recommended UHS device under conditions regulated by the SD Association.
Utilizing Toshiba Memory Corporation's 3D Flash memory technology (BiCS FLASH™), the M303 achieves greater storage capacities. As a result, the cards are offered in capacities starting at 64 GB, 128 GB, and 256 GB. The 256 GB card is capable of storing more than 30,000 high-resolution images [4], or more than 5 hours of 4K video [5]. Operating in a temperature range of -25°C to +85°C [6], the M303 is shockproof [7], X-ray resistant [8] , and waterproof [9], combining reliability and high-speed performance even under harsh conditions. M303 cards come with a five-year warranty [10].
"The M303 allows users to store and access large amounts of high-resolution content without having to stop recording videos to change cards or delete files to free up memory. The cards also offer improved performance when writing data from smartphones to microSD cards compared to our previous model [11] ," commented Sandrine Aubert, Product Marketing Manager at Toshiba Memory Europe.
The M303 cards will begin to be offered at the end of Q1 2018. The first samples will be on display at the Toshiba Memory Europe booth (Hall 4, Stand 4A5Ex) at the Mobile World Congress in Barcelona, Spain, between February 26 and March 1, 2018.
Grades:
[1] One Gigabyte (1 GB) means 10⁹ = 1,000,000,000 bytes using powers of 10. However, a computer operating system reports storage capacity using powers of 2, so 1 GB = 2³⁰ = 1,073,741,824 bytes, thus showing less storage capacity. The available storage capacity (including examples of various multimedia files) will vary depending on file size, format, settings, software, and operating system, among other factors.
[2] 1 MB/s is calculated as 1,000,000 bytes/s. These values are the best values obtained in specific test environments at Toshiba Memory Corporation. Toshiba Memory Corporation does not guarantee the use of read or write speeds on individual devices. Read and write speeds may vary depending on user specifications, such as the devices used and the file size read or written.
[3] An SD Video Speed Class 30 (V30) memory card indicates a minimum write speed of 30 MB/s with UHS-I and UHS-II devices. V30 SD memory cards support 4K and Full-HD video recording. 4K video recording functionality may vary depending on the devices used and other factors, such as file attributes and/or size.
[4] Approximate shots at 18MP. Assumed compression rate = 1/4. The number of shots varies depending on the subjects of the photograph, shooting conditions, resolution, and compression rate.
[5] Approximate 4K Movie playback time (100 Mbps). Actual playback time depends on the movie device, resolution, and compression rate. 1 Mbps = 1,000,000 bps.
[6] This is based on test results by Toshiba Memory Corporation. Operation in all situations is not guaranteed.
[7] The product (card only) may function after being dropped by gravity from a height of 5 m (based on test results by Toshiba Memory Corporation).
[8] ISO7816-1 equivalent. In accordance with ISO7816-1, the product may function after exposure to 0.1 Gy of X-rays.
[9] IPX7 equivalent. In accordance with IPX7, the product may function after being submerged for 30 minutes in static water at room temperature (15°C to 35°C) at a depth of 1 m.
