microSDXC Memory Card with Full Size Adapter, A2, U3, Read Speed up to 100 MB/s, 512GB, Black

Great card--plugged it right into our UniFi Dream Machine 7 to upgrade the storage and it booted right up no problem. Quick, easy and affordable.

Came exactly as described worked perfectly no issues, storage is legitimate and fast.

Picked this up to expand storage and it's been rock solid. Fast read/write speeds, recognized instantly by every device I've tried it in, and the price point is hard to beat for 512GB. Amazon Basics doesn't mess around with their storage products — this is the same quality you'd expect from a name brand at a fraction of the cost. Would buy again without hesitation.

Still working.

I went to a micro SD chip for my phone one because I do a lot of writing in areas not accessible to internet. I needed about 400gb of storage. I decided to try the Basics 512 micro chip. I tried to download as much as I could as fast as I could. After a medium period I kept getting no chip chip available. At first I thought that it was my phone, but every thing checked out okay. Then I thought that the chip was defective. After a cooldown everything worked just fine and I could down load again. What I figured out was that I was downloading too much to fast. The download was creating too much heat for the tiny chip. I am not sure if some of the big name chips would do better. I ended up using 395 GB of storage. Retrieval is lightening fast under normal use. What really fries my mind is that my moto g 5g and a basic chip can really hold 760 gigs of information in my pocket.

I own 4 vantrue dashcams of 3 different models, and this product fits every one of them (with the exception of size fit sometimes 512GB does not work on older models with max 256GB). For comparison, I had to return the Sandisk one even if it has v30 too, because it gives error on all my dashcams even after multiple formatting on my desktop. No observable lag during recording.

Bought this 512GB card 10 months ago for IP camera. It records 24/7 recodings last about 14 days at full 3K HD settings still working fine. If I would have known that this would go up in price I would have bought like 6 of them...I bought it for $26 back in September 2026....now it's almost $100 😮

Excelente calidad y mejor el precio. amazon basics es igual a la calidad de las marcas mas reconocidas

Estaba buscando una tarjeta SD para mi Nintendo Switch y no quería gastar demasiado, pero tampoco comprar algo de mala calidad. Encontré esta opción en Amazon y, por el precio y los 512 GB, me pareció una buena elección. La compré y hasta ahora va muy bien. No me ha dado ningún fallo, funciona correctamente y llegó bien protegida. La capacidad es más que suficiente para tener bastantes juegos instalados sin preocuparse demasiado por el espacio, así que en ese sentido cumple perfectamente.En general, estoy contento con la compra y la recomendaría si buscas algo económico pero fiable para la Switch.

Ich bin sehr angenehm überrascht von der Karte. Zunächst: Die Karte hat 512 GB. Ich lese hier in manchen Rezensionen, dass sie nur 476 GB hat. Das stimmt aber nicht, sondern das ist ein Darstellungsfehler in Windows. Sie hat 476 GiB. Das wäre richtig. Windows lässt das "i" aber weg und schreibt 476 GB, was falsch ist (und auch in Windows schon immer falsch dargestellt wurde). Wer sich über die Unterschiede und die Historie informieren möchte, empfehle ich einen Blick in den Wikipedia-Artikel "Binärpräfix". Nun zum Speicher an sich: Nachdem Speicher meiner Meinung nach aktuell überteuert, habe ich nach Alternativen zu meinem "Haus- und Hoflieferant" (bisher immer SanDisk) geschaut und bin hier fündig geworden. Die Karte von Amazon Basics (ich habe "nur" die "Normal Speed") genommen, muss sich überhaupt nicht hinter einer SanDisk Extreme Pro verstecken. Siehe Screenshot. Und ich habe die Einstellungen in CrystalDiskMark 9.0.2 angepasst, so dass die Testzeit 30 Sekunden (statt der üblichen 1 Sekunde) beträgt, um thermische Effekte (thermal Throttling) mit einzubeziehen. Aber auch da gibt es mit der Karte von Amazon Basics keinerlei Probleme. Daher: 100% Empfehlung! Meines Erachtens aktuell bestes Preis-Leistungs-Verhältnis am Markt.

Ce n'est sans doute pas le top du top de la technologie mais pour un prix raisonnable on a une bonne capacité et une rapidité correcte. Option à examiner avant de faire un achat qui risque d'être bien plus onéreux sans offrir de meilleurs résultats

Till this date i have only purchased Sandisk memory cards as it is the most recognized & reliable brand name.So far they have all performed as expected however the price had been on the higher side which remains the same today.While ordering this was bit hesitant about it's genuineness & Performance however after getting to use it for more than 2 months still i can't believe my luck for getting 512gb for just 2,500 Inr during diwali sale.The only negative is that they don't have 1 Tb card available as that's not been listed on the website.Even if it's for 5,000 Inr i don't think anyone would mind paying for as the rest are double the price i quoted.

​"Ho acquistato la MicroSDXC Amazon Basics da 512 GB specificamente per la mia Insta360 X4 e sono rimasto molto soddisfatto. ​La X4 richiede una scheda molto veloce per gestire il bitrate elevato delle sue riprese a 360 gradi. Questa scheda, con specifiche A2 e U3, ha superato la prova: ​Registrazione Perfetta: Ho registrato sessioni prolungate in 5.7k e non ho riscontrato alcun errore, interruzione o frame perso a causa della lentezza della scheda. Questo dimostra che la velocità di scrittura è adeguata. ​Affidabilità: Non ho avuto problemi di surriscaldamento o corruzione dei file, un aspetto cruciale quando si usano action cam. ​Ottimo Prezzo: Considerando le prestazioni di alto livello necessarie per la X4, il rapporto qualità-prezzo di questa Amazon Basics è davvero imbattibile rispetto ad altre marche più costose.
