Amazon Basics microSDXC Memory Card 128GB with Full Size Adapter A2 U3 Read Speed up to 100MB/s Black

全く問題なく使えます！コスパ良し♡

スマホのアプリストレージ用に購入しました。 問題なく作動してます。 これを買う前に買った安いものが容量詐欺のメモリーカードだったので不安でしたが、これはちゃんと容量も記載の通りで速度も速く申し分ないです! このスペックでこの価格なら買いです!

アクションカメラ用に購入しました。Amazonベーシック製は初めてでしたが、結果的にとても満足しています。 まず、読み取り速度がしっかり出ます。公式の「最大200MB/s」には届かないものの、実測で170MB/s前後と十分に高速。4K動画の保存や転送もスムーズで、動作の引っかかりは感じませんでした。 1TBという大容量なので、長時間の動画撮影や写真データの一括保存にも余裕があります。旅行先でGoProやOsmoなどを使う際にも、容量を気にせず撮影できるのは本当に助かります。 付属のSDカードアダプターもしっかりしており、PCへのデータ移行もスムーズ。差し込み時の緩さや接触不良もなく安心感があります。 気になった点を挙げるとすれば、フォーマット時に少し時間がかかることと、初回使用時に一度エラーチェックをした方が安心という程度です。 全体として、信頼性・スピード・コストのバランスが非常に優れていると感じました。ブランドにこだわらず、実用的でコスパの良いmicroSDを探している方には、間違いなくおすすめです。

一定のクオリティは担保されており、動作不良も現在ありまさん。コストパフォーマンスも高いため、スマートフォンにしよつしております。

PCでは問題なく使えましたが、iPhoneでは認識しなかったので一応書いておきます。

Amazonの偽物Micro SDXCの多さに辟易してたところにAmazon Basicで中身が保証されたものが登場したので 同時販売中のAmazon Basic USB-Cカードリーダーとセットで注文。価格は18136円でちょっと割高。 ・H2testwは１TB問題なし。 ・カードリーダーによって速度差がかなり出るので別売りAmazonベーシック microSD カードリーダー USB C 3.0がおすすめ。（1009円）手持ち環境ではW:186MB/s R:206MB/s ランダムライト4k:7.7MB/sと優秀 ・書き込み中はかなり熱くなる（触り続けられないレベル）読み取り時は問題なし ・1年保証付 SanDiskや東芝以外で新たな良い選択肢が出てきたと思います。

オズモポケット３用に買いました。問題なく作用しています。値段も手頃でよい買い物をしたと思います。

プライベートブランドとはいえ他のメーカー品と遜色ない物です。ちゃんと高速で読み書きしています。

Ok

Chegou em otimas condições, não tive como testar muito mas consegui saber que funciona.

Fast micro sd card. Uses for video surveyance.

Been using it for 2 months now, have not faced any issue, looks good, nice quality, have not faced any data loss, supports most android phones that can support high memory.

This is a fairly (and surprisingly) decent Micro SD/uSD card reader from Amazon Basics that's reasonably well-made and for the most part works as expected without issues. It's reasonably small and compact although far from the slimmest that I've come across and tested due to its odd and slanted shape that's just weird. It has a typical plastic shell that's certainly not something to write home about; however, it does have a spring-loaded card slot, which is a surprise to me (and indeed a pleasant one at that). As for its dimension, it's about 25 mm in length at the shortest side and 29 mm at the longest. As for width, it's about 18 mm at the shortest and 23 mm at the widest. Finally, the thickness is about 11 mm; however, the slanted side has a length of 12 mm measured at the surface. As far as data transmission is concerned, it's able to provide the [nearly] max speed supported by the various Micro SD cards that I've tested and the best result is about 175.25 MB/s for read and 155.85 MB/s for write, which is again fairly good. This particular card reader also supports OTG that many others don't, so that's certainly a point in its favor. Before purchasing this, I tried about half a dozen UHS-I card readers from various well-known brands including Kingston, UGREEN, and TP-Link etc. just to name a few. However, most of them weren't able to achieve speeds faster than 104 MB/s (which is the max speed for UHS-I), and for the few that could go beyond 104 MB/s, they were capped at roughly 150 MB/s, which was weird. The max speed for UHS-I is 104 MB/s and that limit is increased to 156 MB/s (full-duplex) or 312 MB/s (half-duplex) for UHS-II; however that requires the use of an additional row of connectors on the cards as well as the card readers that relatively few have adopted even today. ★ In the meantime, proprietary technologies have been developed by SanDisk and others to bump up the existing 104 MB/s limit to something much higher, including DDR200 (170 MB/s) and DDR225 (200 MB/s) and so on. This is the ONLY card reader that I've tested in the last month that's actually able to achieve 175.25 MB/s (max 180 MB/s for the card in question) via UHS-I interface. Kingston used to have one that actually worked (from about 3+ yrs) but that's no longer the case with the new version that's available at the moment, so if you need a UHS-I card reader that actually works to go beyond 104 MB/s at the moment, this is THE card to get. ≡ Value All things considered, this is a fairly decent uSD/Micro SD card reader that's fairly small/compact and works as expected without issues. It's the ONLY UHS-I card reader (out of the half a dozen or so cards tried) that's able to go beyond 104 MB/s (max 200 MB/s claimed) imposed by the standard. I just wish that it has a slimmer and rectangular shell instead of one that's oval and slanted at the rear, which is just odd and weird. It's reasonably priced at $10 for what it provides and its overall build quality, features (i.e. DDR225, 200 MB/s), usability, versatility, and performance.
