What we found
A cheap category with a long, thin tail
microSD cards are one of the few consumer electronics categories where the entry price and the median price are close together. Our sample's minimum was $12.99 and its median $36.99 — a gap of roughly $24. But the maximum stretched to $169.99, and that single high-end listing is enough to lift the average price to $44.18, about $7.19 above the median.
The banded distribution makes the shape explicit. Twenty-three of 31 listings (74%) sit in the $13–$52 band. Seven (23%) land in $52–$91. The $91–$131 band is completely empty — zero listings. Exactly one card (3%) occupies the $131–$170 band.
| Price band | Listings | Share |
|---|---|---|
| $13–$52 | 23 | 74% |
| $52–$91 | 7 | 23% |
| $91–$131 | 0 | 0% |
| $131–$170 | 1 | 3% |
That empty middle-upper band is the most striking structural feature of the dataset. In this sample there is effectively no $91–$131 microSD market: shoppers encounter a dense mass of sub-$52 cards, a thinner tier of $52–$91 options, and then a single jump to the top of the range.
Brand concentration is unusually high
Of the 31 listings analyzed, SanDisk-branded products appear 12 times once both capitalization variants are counted — 10 listings tagged "SANDISK" (32%) and 2 tagged "SanDisk" (6%). No other brand reaches more than 2 listings.
| Brand | Listings | Share |
|---|---|---|
| SANDISK | 10 | 32% |
| GIGASTONE | 2 | 6% |
| SanDisk | 2 | 6% |
| Patriot | 2 | 6% |
| Lexar | 2 | 6% |
| PNY | 2 | 6% |
The remaining listings are split among brands that each appear too infrequently to register in the top-brand tally. The practical effect for a shopper: roughly one in three microSD listings encountered on a search page carries the SanDisk name, and the runner-up brands — GIGASTONE, Patriot, Lexar and PNY — each hold a 6% slice.
Ratings are high and review counts are deep
Every one of the 31 listings in our sample carried both a price and a rating, giving full coverage with no missing values. The average rating across the sample was 4.64★.
Review depth is the other notable signal. The median listing had 13,868 ratings, and the 31 listings together represent 1,316,798 ratings. For a category where the median product costs $36.99, that is an unusually well-reviewed shelf — a function of both the low price point and the long commercial lifespan of individual SKUs.
Sponsored placements accounted for 10% of the listings captured.

Methodology
- Sample: 31 current Amazon listings returned for the search term "microsd card".
- Source: Analysis of live Amazon marketplace listings. No products were purchased, benchmarked, or physically tested.
- Analyst and date: Compiled by BytePlaza on 2026-09-20.
- Coverage: 31 of 31 listings had a listed price; 31 of 31 had a listed rating.
- Fields: Prices, star ratings, rating counts, brand names and sponsored flags are recorded exactly as displayed on the listing at the time of collection. Brand strings are reported as listed, which is why "SANDISK" and "SanDisk" appear as separate entries.
- Limits: Listing prices fluctuate; figures represent a single point-in-time snapshot. Percentages are rounded, so band shares may not total 100%.
