Navigating the vast selection of microSD cards on AliExpress can feel like a gamble. With prices often significantly lower than retail, it's tempting to grab a deal, but the risk of receiving counterfeit cards with fake capacities or abysmal performance is real. Understanding which brands offer genuine value and reliability is crucial. This analysis synthesizes user reviews, expert testing, and forum discussions up to April 20, 2025, to provide clarity on the trustworthiness of various brands available on the platform.
AliExpress hosts a massive array of microSD cards, ranging from internationally recognized brands to obscure Chinese manufacturers. The primary challenge lies in distinguishing genuine products from fakes. Counterfeit cards often report inflated storage capacities (e.g., a card showing 1TB might only hold 32GB) and exhibit extremely slow read/write speeds, leading to data corruption and loss. While significant savings are possible, due diligence is required.
User reports and tests reveal a pattern: established brands with official storefronts on AliExpress, like Lexar, tend to offer more reliable products. However, even well-known names like SanDisk and Samsung are frequently counterfeited on the platform, making seller reputation and user reviews (especially those with test results) critical evaluation points.

Here's an analysis of the specific brands you inquired about, based on synthesized information from user experiences and available tests:
Consistently ranked as one of the most reliable options on AliExpress. Lexar, now owned by the Chinese memory manufacturer Longsys, benefits from a strong international reputation and manufacturing oversight. Users widely report receiving genuine cards that pass capacity and speed tests (often meeting or exceeding Class 10 / UHS-I specifications). The presence of official Lexar stores on AliExpress adds a layer of trust. It's frequently recommended for demanding applications like cameras and handheld gaming devices.
Example of a Lexar microSD card, known for reliability.
An internationally recognized Taiwanese brand with a solid reputation for memory products. Adata cards purchased on AliExpress are generally considered reliable, offering consistent performance and good value. While perhaps not as frequently highlighted as Lexar *specifically for AliExpress purchases* in some discussions, its overall brand trustworthiness makes it a strong contender. Users report good real-world performance and reliability for everyday use.
A well-regarded Chinese flash memory manufacturer. Netac cards are frequently cited alongside Lexar and Kodak as reliable and affordable choices on AliExpress. User tests confirm they typically deliver the advertised capacity and speeds (meeting V30/U3 standards where applicable). It's a popular choice for budget-conscious buyers seeking dependable performance without paying a premium for Western brands.

While historically known for photography, Kodak-branded microSD cards on AliExpress have a somewhat mixed reputation, though often positive *within the context of AliExpress*. Many users report positive experiences when buying from official Kodak stores or high-volume sellers, with cards passing tests for capacity and speed (sometimes reaching ~98MB/s read). However, some sources note these might be OEM products with variable underlying quality. It's seen as a relatively safe bet *on AliExpress* compared to unknown brands, but perhaps not a top-tier choice for critical data compared to Lexar or Adata.
This lesser-known brand has garnered some positive attention. Specific tests reported online found XrayDisk cards purchased on AliExpress to be legitimate, offering accurate capacity and respectable read/write speeds for the price. They are often recommended as a decent option for non-critical, short-term storage. However, long-term reliability data is scarcer compared to more established brands, warranting some caution.
More known for tablets, Teclast also offers microSD cards. Reviews are sparse, but suggest average or moderate reliability. They might suffice for general use, but aren't typically highlighted for high performance or exceptional durability. Information is limited compared to other brands.
While Lenovo is a major global brand, its microSD cards are less common and discussed. Information suggests performance and legitimacy can be mixed, potentially depending heavily on the specific seller and whether the product is genuinely sourced. Reliability is uncertain specifically for their microSD line on AliExpress.
Associated with Hikvision (known for surveillance), Hiksemi memory products exist but have limited independent reviews in the context of AliExpress microSD cards. Some sources mention inconsistent performance or concerns about authenticity, suggesting lower reliability or insufficient data to recommend.
Very limited reliable information exists for this brand. One mention of a "microdata" card test was positive for a small capacity, but "Microdrive" itself lacks verification. Due to the lack of data, it's considered a risky choice.
Explicitly flagged in multiple sources as being associated with fake cards. Users report KRY cards advertised with large capacities (e.g., 256GB/512GB) often having much smaller real capacities and very poor performance. This brand appears highly unreliable and should likely be avoided.
Minimal information or user testimonials are available for Fanxiang. The lack of data and anecdotal mentions of potential counterfeits make it a high-risk purchase.
This name doesn't correspond to a well-known, verified brand in the search results. It might be a misspelling, a very obscure brand, or potentially associated with low-quality/fake products. It's unranked due to lack of information.
"TF Card" (TransFlash) is simply the older name for microSD. "TFMicroSD" is not a brand name but a generic descriptor. Cards sold under such generic labels vary wildly in quality and are often associated with fakes.
This mindmap categorizes the discussed brands based on the synthesized reliability analysis, helping visualize the landscape from trustworthy options to those best avoided.
Based on the synthesis of available reviews, tests, and user reports specific to AliExpress purchases, here is a ranked list of the brands you inquired about, from most to least reliable. Brands with insufficient data are noted.

9 | Microdrive | Very limited data, considered risky due to lack of verification. High Risk / Limited Data. |
10 | KRY | Explicitly associated with fake capacities and poor performance. Very High Risk / Avoid. |
11 | Fanxiang | Minimal information, anecdotal risk of fakes. Very High Risk / Avoid. |
- | Sandian | Unknown brand, insufficient information for ranking. Avoid. |
- | TFMicroSD | Generic term, not a brand, cannot be ranked. Avoid generic labels. |
Based on the available evidence and consensus across multiple sources, Lexar (including its Foresee line by parent company Longsys) emerges as the most reliable brand among those listed for purchasing microSD cards on AliExpress.
