Great Cards
Nice cards. Very fast and test put great. While I have had them only for a few days, they are better than other small 32 Gen cards

Lexar Storage Is Reliable
I've used Lexar micro SD cards without failure. They are reliable and compatible for all my cameras. The transfer speed is optimal and storage capacity is sufficient my use. They are easy to install because they always fit properly. Recommended.

512GB at a great price, some compromises
The 512GB can't be beat on price. There are some caveats. 1) Windows 7 hated the card but Windows 11 was OK with it. Been writing to it for about 3 hours straight now. 2) The advertised write speed is for small files. Anything substantial in size writes no faster than 36MB/s and that was achieved in bursts of up and down. 3) Many hours later, this card is very slow towards the end of its capacity. I'm close to the 468GB and it's dog slow now on the writes. It caused Windows Explorer to crash. Now Windows wants to constantly fix the card. I won't be writing that often so it's not a huge deal breaker.

Good for dahscam
I installed this Lexar microSD card in my dash cam and it has been working great. It is fast enough for continuous recording and handles video without any issues. Setup was easy and it worked right away. For the price, this card offers very good performance and reliability. Overall, it does exactly what I need it to do and I would recommend it for dash cams or similar devices.

Worked great
I needed to replace the micro sd cards in my GPS and an internet radio. I popped the cards, redownloaded the maps, and updated the firmware on the internet radio. The Lexar cards worked perfectly.

I have been using Lexar SD cards for awhile now, in cellphones, GoPro and SLR cameras as well as media players and have to say I am very happy with the performance. As long as you can get - or make sure - it's a true, legitimate Lexar card, you really can't go wrong with the brand. This was a very good price for a 256GB microSD card, and now half loaded with media and such in my phone, I won't be worrying about storage for time to come. Card is fairly fast - moving large files and music will always take more time no matter the rated speeds - but doesn't heat up, and am expecting the same longevity out of it as I have found with previous Lexar cards. I would definitely recommend the card and brand to anyone wanting some good, reliable bulk storage in any of their electronics. If I run into any problems or cause to change this opinion, I will update this review at that time.

輸入ものなので信用している風見鶏さんで購入しました。 初期不良もなく、メモリカード間のファイル移動もエラーなしで終了しています。 耐久性はまだ2ヶ月足らずなので未評価ですが、速度とコスパは非常に満足です。 SwitchはソフトをほとんどDLで購入しているので512GBの容量は頼もしいですね。 ベンチの結果は以下の通りでした。 Sequential Read (Q= 32,T= 1) : 92.443 MB/s Sequential Write (Q= 32,T= 1) : 75.810 MB/s Random Read 4KiB (Q= 32,T= 1) : 9.319 MB/s [ 2275.1 IOPS] Random Write 4KiB (Q= 32,T= 1) : 3.937 MB/s [ 961.2 IOPS] Sequential Read (T= 1) : 91.657 MB/s Sequential Write (T= 1) : 75.922 MB/s Random Read 4KiB (Q= 1,T= 1) : 8.907 MB/s [ 2174.6 IOPS] Random Write 4KiB (Q= 1,T= 1) : 3.673 MB/s [ 896.7 IOPS]

Presa per il registratore audio, non ho fatto prove di velocità ma fa egreggiamente il suo dovere. Per il 2025 il prezzo è eccessivo ma è nell' elenco di quelle ufficialmente supportate dal registratore, perciò l' ho presa comunque.
