Our Verdict

Amazon Basics' 256GB card is the budget-brand answer to the 256GB SanDisk Ultra above — same 100MB/s-class speed tier, same general use case, but at $66.49 it actually costs more than SanDisk's own 256GB Ultra at $59.99, which is worth knowing before buying on brand-recognition alone. Where it does make sense is for buyers already satisfied with the 128GB Amazon Basics card in this lineup who want the same warranty terms and support experience at higher capacity — the 1-year warranty is shorter than SanDisk's 10-year coverage, a real trade-off for a card meant to hold years of photos or footage. With over 26,000 reviews at 4.7 stars it's clearly reliable in practice. For this specific capacity tier, the SanDisk Ultra 256GB is the better buy on both price and warranty; choose this only if you specifically want to stay within the Amazon Basics line.
