What we found
A cheap category with an expensive tail
microSD cards are, by the numbers, an inexpensive purchase. The median price of $43.99 means half the priced listings in our sample cost less than roughly $44. But the average price of $58.29 runs about $14 higher than the median, and the distribution explains why: the bulk of the market is compressed into the low end, while a thin upper tail stretches to $259.99.
| Price band | Listings | Share |
|---|---|---|
| $10–$72 | 29 | 81% |
| $72–$135 | 3 | 8% |
| $135–$197 | 3 | 8% |
| $197–$260 | 1 | 3% |
Put differently: four out of five listings cluster in a single band under $72, and just seven listings — 19% of the priced sample — account for the entire range above it. For shoppers, the practical implication is that the "typical" microSD decision happens within a narrow $10–$72 window, and stepping outside it generally means buying into high-capacity or specialty territory rather than paying for incremental quality.
| Price statistic | Value |

Brand concentration is unusually high
Among the 37 listings analyzed, SanDisk appears under two capitalizations in the marketplace data — SANDISK with 9 listings (24%) and SanDisk with 7 listings (19%). Treated as one brand, that is 16 of 37 listings, or 43% of the sample. No other brand reaches double digits in share.
| Brand | Listings | Share |
|---|---|---|
| SANDISK | 9 | 24% |
| SanDisk | 7 | 19% |
| Patriot | 3 | 8% |
| PNY | 3 | 8% |
| KEXIN | 2 | 5% |
| GIGASTONE | 2 | 5% |
The remaining listings are spread across smaller or single-listing brands. That long tail matters: it means a shopper scrolling search results encounters one dominant name repeatedly, interleaved with a rotating cast of lesser-known labels.
Ratings are high — and nearly uniform
All 37 listings in the sample carry a rating, and the average is 4.67★. In a category where ratings sit this high and this tightly, star score alone does relatively little to separate products. Review volume is a more useful signal of market traction: the median listing has 10,209 reviews, and the 37 listings together represent 1,379,020 reviews. That volume suggests a mature, heavily-purchased category rather than one with many new or untested entrants.
Finally, 16% of the listings we captured were sponsored, a reminder that a meaningful slice of what appears in a default search is paid placement rather than organic ranking.

Methodology
- Sample: 37 current Amazon listings returned for the search term "microsd card."
- Priced listings: 36 of 37 displayed a price; price statistics are computed on those 36.
- Ratings: all 37 listings displayed a rating; the 4.67★ average is computed across all 37.
- Source: analysis of current Amazon marketplace listings. Prices, star ratings, review counts, brand labels, and sponsored flags were recorded exactly as listed at the time of capture.
- Date: analyzed by BytePlaza on 2026-10-18.
- Limitations: no physical testing, benchmarking, or verification of advertised read/write speeds or capacities was performed. Amazon prices and search results change frequently and vary by region, so figures represent a single point in time. Brand names are reported as they appear in listing data, which is why "SANDISK" and "SanDisk" are counted separately in the raw brand table.
