The claim that "the entire Bitcoin blockchain can fit in this memory card" is currently mostly true for most standard high-capacity memory cards, but let’s clarify with up-to-date numbers:
Bitcoin blockchain size as of June 28, 2025:
668.36 GB (gigabytes)1.Typical memory card capacities:
SDXC or microSDXC cards now commonly reach 512 GB and 1 TB (terabyte) capacities.
Hard drives and SSDs are available in much larger sizes (multi-terabyte), but memory cards are catching up.
Typical memory card capacities:
DXC or microSDXC cards now commonly reach 512 GB and 1 TB (terabyte) capacities.
Hard drives and SSDs are available in much larger sizes (multi-terabyte), but memory cards are catching up.
Analysis:
A standard 512 GB memory card is not large enough to hold the Bitcoin blockchain as of June 2025.
A 1 TB (1,000 GB) memory card is sufficient, as the blockchain is currently about 668 GB1.
If the claim references a 1 TB memory card, it is accurate. If it references a smaller card, it is not.
