Superfast and works in a nikon Z63
This is my third next storage CF express card works perfectly in my Nikon Z63
Greg Kanyicska –
Speedy memory card
This is not a technical analysis regarding Nextorage’s write speed, but it feels fast.
Bob H. –
Well designed card. Stays cool.
Works perfectly in my Nikon Z8. Tolerates the high volume dump from the camera shooting raw at 20fps.
Kevin –
My new favorite card.
So far so Good! Blazing fast for stills work. Seems very stable for 4k 120 video and 8K 60. Mainly used in a Z9. Bought it mainly for video work

For fast sustained speeds buy the 1TB works with Nikon zr
It works really well with the new Nikon zr. It unlocks raw codecs. I haven’t had overheating problems at all! Do not buy the yellow expensive version of this card because this 1tb blue version has the same sustained speeds of the other yellow version. Be aware only the 1tb version of this card has over 1,000 of sustained speed. The lower capacities do not have it.

easy to get and works well
Easy getting it and tested well on my camera

Good bang for the buck.
The cards have been great in terms of write speed and build. No issues at all. Best deal out of all I could find on Amazon.

Writes barely faster than B2 SE, doesn’t meet expectations
Purchased the higher tier upgraded NX-B3SE512G expecting it to do what it says on the tin (3,900 MB/s read and 3,400 MB/s write) , but surprise surprise, you better read the fine print. Sticking the card in my Z6 III, trying to record ProRes RAW or N-RAW led to the camera stopping the recording after about 10 seconds.Doing some testing with my M4 Max and a ASM2464PD USB4 40 Gbps CFe reader, the card tests pretty slow. QD1 write speed is around 800 MB/s, and write performance drops off a cliff as the queue depth increases.Reading the fine print on the listing calls out that this 512 GB card has a “sustained write” speed of 850 MB/s, which is potentially not fast enough for 6k RAW. Looks like the 1TB card is supposed to have double the minimum “sustained write” speed. For what it’s worth I couldn’t get any write to the card faster than 840 MB/s, sustained or otherwise.Save your pennies and buy the B2-SE card series. In the B2 SE line, the 512 GB card listing says it’s sustained write speed is 800 MB/s. Why pay double for less than 50 MB/s more?

品質よさそうですね、スピードも満足、今のところ不具合もなし。キヤノンの1Dx3で活用、全く問題なし最大連射でずっととってもバッファ切れしなく好きなだけ連射できる凄く書き込み速度が速くてSDカードとかとは比べ物にならないですね最高ですね。

Acheté la version 1024 en promo.Utilisée sur un Nikon Z8 pour de la photo.Fonctionnement parfait en particulier pour les rafales (buffer infini en raw he*). Ne chauffe pas.Je ne fais pas de video.

Bien reçu dans le delai

Die Speicherkarte ist für meine Fuji GFX 100 ii. Funktioniert tadellos. Geschwindigkeit ist mehr als OK. Im Vergleich zur ebenfalls genutzten UHS-II SD Karte „gefühlt“ schneller. Der Preis war für die Größe der Karte relativ gut (Cyber). Auf lange Sicht wird sich zeigen, wie sie sich verhält. Momentan würde ich sie wieder kaufen!
