Kingston Technology Corp. Canvas Go! Plus 512 GB SDXC U3 V30 memory card

512 GB SDXC UHS-I card

The Kingston Canvas Go! Plus SDG4/512GB is a 512 GB SDXC memory card built to the UHS-I interface with Class 10, U3 and V30 speed ratings. It targets photographers and videographers who need reliable capacity for 4K UHD video and burst-mode stills on DSLR or mirrorless cameras. The card is supplied new and ready for immediate use in compatible slots.

Sustained write performance

Rated sequential write speed reaches 100 megabytes per second, while the V30 marking guarantees a minimum sustained write of 30 megabytes per second across the full capacity. This allows extended 4K recording sessions and continuous high-resolution bursts without the buffer stalls that slower cards exhibit after a few seconds. Read speeds of up to 160 megabytes per second accelerate offload to a workstation.

Upgrade path and limits

The card replaces lower-capacity or lower-speed SDHC and SDXC cards that cannot maintain V30 sustained write or that lack the 512 GB headroom for long shoots. It is not suited for devices that require UHS-II or UHS-III bus speeds, nor for workflows demanding write throughput above 100 megabytes per second. Buyers needing higher sustained write bandwidth or larger single-card capacity should consider faster bus standards.
