PNY 64GB EliteX-PRO90 U3 V90 UHS-II SDXC Flash Memory Card, 4K Ultra HD

nice and fast in my camera

Es una memoria súper rápida, buena para sony

Works great

Items can on time and work in my Sony A7, but one came in just a small plastic bag no housing for the card itself so i was wondering if the card was new i don't know i can only trust what Amazon says.

It makes no sense to skimp on what amounts to "digital film" with a high end camera and lens. This card delivers. Grabbed it on sale and it performs well. PNY as a brand always manages to deliver high quality at excellent price... And NOT made in China.

The card works as well as you could hope, my only issue is that I bought merely 64GB cards; you probably want more storage if you do burst shooting/video that needs the speed of this card. I could fill the card in 5 min if I kept burst shooting as fast as it emptied the camera cache to the card. That tracks as at 250MB/s you can transfer 64GB between 4-5min. For my camera, it let me do about 1000 photo's on 64GB. It can do bursts upto 200 photos. Again, you see my mistake. Unless you shoot singles and just need fast exporting, you probably want a larger card.

I don’t doubt that this chip meets its claimed rating but I was curious to see how much that speed meant in my workflow. My attempts to see the difference it’d make in a camera were frustrated because I had no way to conduct tests that I felt were fair. I had on hand a chip that’s rated at almost exactly 50% of this one’s rating so I thought it’d be obvious how long the red/writing light stayed on after a few shutter bursts. I never felt confident that my tests were valid although my sense was that this chip was markedly faster than the one rated at 50%. That may have been hopeful confirmation bias, though. Instead, I conducted a test I could time well. I copied 657 files totaling 18.1 g of data to and from an SSD through a USB 3.1 port. My results are below: From SSD to USB slow chip: 17:28 From SSD to USB this chip: 16:53 From USB to SSD slow chip: 17:24 From USB to SSD this chip: 17:15 The results are minutes:seconds. Since the SSD is a fast one, I’m guessing the disappointing lack of meaningful difference is the poor USB 3.1 port performance. The upshot for me is that where I want faster performance most – moving photos/videos from the card to the SSD, a faster chip doesn’t help me. If I was a sports shooter who needed to write hundreds of snaps quickly, this card would be valuable but for me who rarely shoots more than one image over a five minute period, it’s a bit of a wash.

Fast for cameras that support UHS-II. The read and write speeds are dependent on the speed rating (V90, V60, V30, etc.) The UHS-II form factor makes possible the higher speeds but those super high speeds are still very expensive. An SDXC UHS V90 card is faster than an SDXC UHS-II v60 card.

Ottima scheda utilizzata per sony alpha 7 iii come scheda principale. Efficace e veloce, pagata in offerta ad un prezzo conveniente, consigliato e compatibile per la maggior parte dei device

Good quality - haven't missed a beat.

Works fine

La tarjeta de memoria es buenísima y el costo también, sin embargo, no pude rastrear la compra y apareció perdido durante 15 días y nadie me dió ayuda o asistencia. De pronto llegó.

Diese SD-Karte ist schnell, schneller als meine R5/R6II übertragen können und dabei günstig im Preis. Sie wurde für die Fuji-X Kameras als 3 beste Karte getestet unter 12 und lag nur wenige Punkte hinter den viel tereren Karten von Sony etc. zurück. Über die Haltbarkeit auf längere Sicht kann ich selbstverständlich nach der kurzen Anwendungszeit keine Aussage machen. Bis jetzt hält sie alles was der Hersteller verspricht und noch etwas mehr.
