Western Digital this week is previewing the business’s first four TB SD card. The machine is being showcased on the NAB commerce present for broadcasters and content material creators and shall be launched commercially in 2025.
Western Digital’s SanDisk Extreme Pro SDUC four TB SD card complies with the Secure Digital Ultra Capacity normal (SDUC, which permits as much as 128TB). The card makes use of the Ultra High Speed-I (UHS-I) interface and is rated for velocity Class 10, subsequently supporting a minimal velocity of 10 MB/s and a most information switch charge of 104 MB/s when working in UHS104 (SDR104) mode (there’s a catch about efficiency, however extra on that later). WD’s SD card can also be rated to fulfill Video Speed Class V30, supporting a minimal sequential write velocity of 30 MB/s, which is believed to be adequate for 8K video recording, above and past the 4K video market that Western Digital is primarily aiming the forthcoming card at.
For now, Western Digital will not be disclosing what NAND is within the SanDisk Extreme Pro SDUC four TB SD card. Given the excessive capability and comparatively distant 2025 launch date, WD could also be targetting this as one among their first merchandise to make use of their forthcoming BiCS 9 NAND.
And whereas not listed in WD’s official press launch, we’d be shocked if the forthcoming card did not additionally help the off-spec DDR200/DDR208 mode, which permits for increased switch charges than the usI normal usually permits by way of double information charge signaling. Western Digital’s current-generation SanDisk Extreme Pro SDXC 1 TB SD card already helps that mode, permitting it to achieve learn speeds as excessive as 170 MB/s, so it could be shocking to see the corporate drop it from newer merchandise. That stated, the catch with DDR208 stays the identical as all the time: it is a proprietary mode that requires a appropriate host to utilize.
Western Digital has not disclosed how a lot will its SanDisk Extreme Pro SDUC four TB SD card value. A 1 TB SanDisk Extreme Pro card prices $140, so one could make guesses concerning the value of a four TB SD card that makes use of cutting-edge NAND.
