Transcend's microSDXC/SDHC 300S cards are the right choice!

Review: Works good so far - I only just got this and haven't used it much yet, so I'll update my review if anything changes but it works as expected so far. I'm happy to see it's made in Taiwan and not China like the SanDisk microSD cards that I was looking at prior to this one. Seems to have better read and write speeds than the Samsung Evo ones. It also came in a plastic case to store the card when not in use which is nice.

I'm happy to see it's made in Taiwan and not China like the SanDisk microSD cards that I was looking at prior to this one. Seems to have better read and write speeds than the Samsung Evo ones. It also came in a plastic case to store the card when not in use which is nice. ### ⭐⭐⭐⭐ Good product! *by K***R on August 25, 2018* Working well so far! ### ⭐⭐⭐⭐⭐ Pretty Live. *by S***A on May 9, 2022* It was like ok. I wouldn't ultimately reccomend it as a product, but it is very niche. The back of the card is vaguely ordinary appearing-ish. ## Frequently Bought Together - Transcend 512GB 300S, Memory Card, microSD, U3, A1, Up to 100 MB/s, for Mobile Devices, with Adapter - TS512GUSD300S-AE - USB3.0 Micro SD Card Reader, 5Gbps 2-in-1 SD Card Reader to USB Adapter, Wansurs Memory Card Reader for SDXC, SDHC, MMC, RS-MMC, Micro SDXC, Micro SD, Micro SDHC and UHS-I Cards (1Pack Black) - SanDisk Ultra SDSQUNS-016G-GN3MN 16GB 80MB/s UHS-I Class 10 microSDHC Card --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/266436710-transcend-usd300-512gb-microsdxc-micro-sd-card-a1-v30-uhs](https://www.desertcart.ec/products/266436710-transcend-usd300-512gb-microsdxc-micro-sd-card-a1-v30-uhs) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-16*
