Im passenden Reader – in meinem Fall der SDDR-A451-GNPNN – liest die Karte mit ca. 600–800 MB/s und schreibt 560–600 MB/s. Soweit wie erwartet. (Die blaue von ADATA schafft 600/260.)In einem herkömmlichen Leser, einem 12 € USB 3.2 von Kingston, sind es ca. 170 MB/s lesend und 154 MB/s schreibend. Super! (Die ADATA nur 100/80.) Schneller sind nur UHS-II die aber hinter SD Express zurückbleiben. (Lexar Gold: 260/180)

It works as it should :p

grossartig gleich schell copiert wie usb sticks am langsamsten copieren die alten festplatten

Schneller geht es nicht mehr

sehr gut

You cannot achieve the advertised speeds without additional hardware. It will be stuck at 90mb/s on standard SD card readers. Kinda of a bait for amateur users who don't know all about the tech. Otherwise solid card though. 1 point redacted cuz of this speed issue and 1 point for it's expensive price... 3/5.

比較的お得に変えました

Utilisé pour transferer mes données de la switch 1 à la switch 2, aucun problème.

Ich glaub, schneller geht es nicht

Premessa: ho acquistato questa SanDisk Express proprio per il mio Nintendo Switch OLED (giacché possiedo parecchi titoli in digitale).Qualcuno mi chiederà: perché hai preso questa così costosa quando avresti potuto prenderne una più capiente ma non "Express"?Risposta semplice: poiché le SD Express saranno le uniche funzionanti anche su Nintendo Switch 2.Tuttavia, siccome conto di rimanere ancora 3-4 anni ancora su Switch 1 e attenderò che esca lo Switch 2 OLED (già rumoreggiato, tra l'altro), ho preferito fare un acquisto del quale posso usufruire sia adesso sia tra 4 anni, senza dover comprare un'altra San Disk.Consigliata.

Update 06/07/2025, Comparing to Onn's Express 256:There is a new budget microSD 256 Express card from Onn that appeared in retail this week coinciding with the launch of the Switch 2. It claims to support up to 800MB/s reads and 600MB/s writes. I picked one up to compare. With larger stress tests (Random reads and writes going up to 5GB instead of the 1GB test I show here), this SanDisk can see its transfer rate drop to a minimum of 400GB/s on writes. For the Onn device, on writes the rate drops to 200MB/s typically, but sometimes as low as 150MB/s as the firmware seems to have trouble keeping up (it stalls completely), nearly 3 times slower on average than the SanDisk. What's worse is that it drops to 400GB/s even for transfers as small as 2GB, 300GB/s for 3GB, and 200GB/s from there on up, while the SanDisk still manages to hold minimum 600GB/s. Keep in mind that most larger games for the Switch 2 are about 20GB or more, and there are a few 64GB or larger. I do not currently own a PNY card to test, but online evidence suggests that it too is slower than the SanDisk, but may be faster than the Onn device. With the way the Onn card stalls on writing, literally stopping occasionally for upwards of a second while testing, I could never recommend it. You get what you pay for with the SanDisk. Full review follows.REVIEW:During play, the Onn express card may be able to keep up due to small transfers and minimal loads, but its stalls will affect things, and during download and game management on the Switch 2, you will definitely see a time impact, probably significant. The good news is that the Onn express card was able to hold up on read tests without stalls, with the same 750MB/s as the SanDisk, but it never really went above 750MB/s for even smaller transfers while the Sandisk peaked at about 990MB/s, above their claimed rate. I am sure some caching was involved in that number, but the system caches the Onn in the same way, so there is a significant difference.Great high-speed card if you have a reader that supports Express. This card also outperforms even on a standard controller due to its rapid response time and excellent IOPs (measure of the number it can handle per second). Does well enough to be considered as an external drive on the Mac, though an M.2 reader enclosure will outperform it on specs. Can't beat it for portability.For sustained throughput on the SanDisk Express reader, this can't be beat, easily outperforming any other card I have from 4X to 20X faster. Camera file transfers happen at about 1GB/s. No drivers needed for any recent OS, though Ubuntu has a recent bug that will prevent those devices from attaining full speed unless an external Express-capable reader is used.

Sd Karte funktioniert einwandfrei

170 MB/s ist die Lesegeschwindigkeit mit dem empfohlenen SanDisk PRO-READER - Kartenleser (SD, microSD) - USB-C 3.2 Gen 1. Ich habe die Karte in den SanDisk PRO-READER gesteckt und mit dem Benchmark Programm DiskMark von EasyUs getestet. Das Ergebnis sind 178 MB/s für sequentielles Lesen und 160 MB/s für zufälliges Lesen UND für sequentielles Schreiben 142 MB/s und für zufälliges Schreiben 85,77 MB/s.Das bestätigt sich auch, wenn ich eine 20 GB große Datei von der Karte auf eine interne m2 SSD mit mehr als 7GB/s Lesegeschwindigkeit (Benchmarkergebnis ist auch als Bild angehängt) kopiere. Dabei erreicht die SanDisk micro SD Express Karte gerade 169 MB/s.Der SanDisk PRO-READER ist an einen 10GB/s USB-C Eingang (siehe Bilder) meines ASUS ROG STRIX B650E-E GAMING WIFI Motherboards angehängt.Keine Rede von "Lesen bis zu 880 MB/s & Schreiben bis zu 650 MB/s"Ich fühle mich um mein Geld betrogen. 66,54 EUR für die Karte und dann 62,92 EUR für den Kartenleser = 129,56 EUR habe ich hergeschenkt. Diese Geschwindigkeiten habe ich auch mit meinen bestehenden SD Karten und Lesern. Wo kann ich das bei Amazon reklamieren??
