SanDisk plans to launch high-capacity SDUC storage cards that break the initial 4 TB barrier. The company targets both standard SD and microSD form factors with capacities up to 8 TB. These new cards require entirely new card readers because current hardware cannot support them.
New storage options require dedicated card readers for immediate use
The Ultra series will include a microSDUC card with 4 TB capacity and a standard SDUC card reaching 8 TB. SanDisk also announced an Extreme Pro series featuring a 4 TB SDUC card. The SD Association confirmed these specifications at Computex.
- SDUC Ultra microSD capacity: 4 TB
- SDUC Ultra SD capacity: 8 TB
- SDUC Extreme Pro capacity: 4 TB
SDUC cards strictly require new card readers to function. Existing SD Express readers cannot handle the new format even if they are brand new models. Users must purchase dedicated hardware to access the expanded storage tiers.
Multiple companies at the SD Association booth confirmed an imminent launch for these products. The cards are set to hit the market shortly, though exact dates remain unconfirmed. SanDisk representatives declined to provide specific details when asked about pricing or release windows.
The company stated it cannot make a statement on current inquiries regarding the new cards. This silence leaves both pricing and specific availability dates unknown at this time. Buyers will need to wait for official retailer listings before purchasing.
SanDisk now offers SDUC storage options that exceed previous capacity limits while demanding updated reader hardware. The Ultra series provides up to 8 TB of space, and the Extreme Pro line delivers 4 TB in standard format.
