Western Digital is launching the SD Association’s Secure Digital Ultra Capacity (SDUC) SD card under the “SanDisk” brand to support multimedia and entertainment workflows, such as high-definition, high-frame-rate video, cameras and laptops, reported in the ad.
The card uses the Ultra High Speed-1 (UHS-1) bus interface, which supports a minimum speed of 10 MB/s with a theoretical maximum transfer speed of up to 104 MB/s, reported. AnandTech. The minimum sequential write speed is expected to reach 30 MB/s, the publication says.
Is 8K recording coming?
With these specifications, the upcoming SD card should be able to support storage-intensive video formats, including 8K, although the card won’t be fast enough to support 8K RAW video recording. That explains why Western Digital first unveiled the offer at the National Association of Broadcasters’ annual event for broadcast and media professionals.
“Attendees will get a preview of the full capacity of the 4TB SD card and learn more about how to expand the creative capabilities of cameras and laptops,”
Western Digital said.
The announcement did not include more information, such as what type of NAND the card uses or whether it supports the DDR200 / DDR208 SanDisk mode, which could allow data transfer speeds of up to 170MB / per license. Western Digital didn’t say how much the SD card will cost either, but given the advanced capabilities and target audience of professional creators, the range is likely to be high-priced.
Six years after the first
WD’s announcement comes six years after the SD Association, which writes SD standards, announced the SDUC standard, which raised the maximum theoretical capacity of SD cards from 2TB to 128TB. As with the many releases of new standards, some enthusiastically believed that SD cards could soon hold 128 TB of storage. But since 4TB isn’t expected to arrive until 2025, “soon” isn’t quite right.
The maximum theoretical capacity of SD cards was 2 TB 9 years ago, but the largest SD cards you could buy at the time were only 512 GB. Today, the largest capacity SD cards are 1 TB (Western Digital also announced plans to release a 2 TB SanDisk Extreme Pro SDXC UHS-I memory card at an undisclosed date), while ‘ s the 2 TB microSD cards were only available this year.
However, SanDisk’s reputation as a reliable storage device is highly questioned among professional and long-term customers. Several lawsuits have been filed over these SanDisk Extreme portable SSDs they are said to have failed unexpectedly. These alleged failures, along with Western Digital’s stiff response to reported data loss, may prompt work-critical storage professionals to consider switching to a 4TB drive.
