I don't shoot a lot of video with my DSLR setups, but when I do I don't have any negative impacts when using the Lexar Professional cards. These were purchased to add to my memory card wallet and have performed wonderfully in both a Nikon D500 (sports) and Nikon D800E (landscape and astrophotography). I'm just an advanced enthusiast who loves his gear and do rely on these to also capture family memories together. It's where a lot of the sports shooting comes from (soccer, cross country, track). They've never let me down. These I purchased in 2022, but the last 128GB I bought is about 3 years old and rock solid. I shoot RAW so I can post-process, and these don't slow down the shooting process or transfer from camera to PC via reader.Been using this on my Z7ii since I didn’t want to dish out all the money to upgrade to CFExpress. This has been working fine for my needs, shooting Lossless RAW + JPEG and occasionally recording video on 4K/24p. I mainly use the camera around the house and on trips for family stuff, so I’m not sure how this would hold up for professionals, but for my use-case it works great.SD Cards are notorious for making absurd claims about their read and write speeds. I hold SanDisk Exteme Pro's in the highest regard, but even those come up with a fraction of the stated speed in my hands-on test with Crystal Disk Mark.Happy to see that these Lexar UHS-II cards, tested on a ThinkPad USB-3.0 port, using a "Sony MRW-S1 High Speed UHS-II USB 3.0 Memory Card Reader/Writer for SD Cards" as interface, and on Crystal Disk Mark 8.0.4, reached superb results - see pictured.In fact the read speed is better than the SanDisk Extreme Pro 300 MB/s in my tests. The write speed is just above half of the SanDisk. This is less than half the cost of the Extreme Pro 300's at the time of this review, so I think that's an awesome value for money for the Lexar.Since I just received the cards - the open question is how long they will last.Using these as 2nd-slot cards in my Nikon Z6 II. Formatted fine, took several pix on them, read them in my computer. Much less expensive than when I bought a 128-gig card a couple years ago. Happy so far!This card has NEVER failed me. I have multiple ones. It processes hundreds of photos in 12 fps RAW files like they are nothing which enables me to capture the moments I want to get. Well worth it!So preparing for a big trip to Alaska, and I was dead-set on bringing my DSLR along. Going someplace as gorgeous as Alaska, means a lot of pictures, and I needed storage capacity.So this came up at a relatively great price. They're huge and I've actually switched to shooting in RAW mode. I mean these things are so spacious and fast, it's transformed how I shoot (and edit) pictures. I always shoot in burst mode, and never ran into an issue where writing was delayed.Not sure really what else there is to say. If you need SD cards with a ton of storage, trust a name brand and consider getting these.perfecta cuando necesitas velocidad para grabar una ráfaga de fotografíaI bought the 250MB write speed because there's a serious step up in price for 300MB. The new digital cameras need a lot of write speed on the memory cards and I find this one very satisfying in that regard. I have no basis yet to rate durability, but capacity and speed are all that I paid for.I don’t think these are the fastest SD card you can get, but they are priced well and work perfectly in my cameras. For me, 128Gb is an ideal size or maybe more than enough to be honest as I don’t do a lot of video shooting, mainly stills. It made me laugh when starting this review however - Amazon ask me to rate the picture quality of these. Given we are talking about storing digital data here, how on earth is a storage device going to control the quality of an image? Anyway, they work well and there have been no issues and they’re certainly much faster than normal standard SD card. I’m sure they’re faster in a standard SD card reader, but maybe that’s my imagination.Works well with my Panasonic HC X1 in 4k mode. One of the review features I am asked for is "softness" (I kid you not). Had to give one star as unfortunately this card is too hard to put into the body.We all know how every tablet, laptop and other device comes with about 8-64 gb which is tiny. I use this card everyday to bust up my laptop storage capacity and I had no problem with it❗️Antes que nada tengan en cuenta que esta sección es para calificar el producto, no al envío ni al vendedor, aquí no comenten nada de eso, porque estas reseñas le aparecen a todos los vendedores que vendan el mismo artículo, por lo tanto si comentan "pésimo servicio, no recomiendo al vendedor etc." puede que estén leyendo un comentario que iba dirigido a otro vendedor. Recuerden esta sección es para calificar exclusivamente al producto. Incluso también yo me llegué a confundir porque veía los mismos comentarios en todas las publicaciones de diferentes vendedores. Amazon debería dejar este detalle pero como no es así por eso este mensaje que hago con la intención de ayudarnos a nosotros mismos para ver reseñar claras que califiquen realmente al producto, porque muchas veces los productos están mal calificados o en su defecto bien calificados pero por cosas como el envío, el empaque, etc. y nada tiene que ver con la calidad o el desempeño del producto, cosa que puede influir en nuestra compra!También consideren hacer sus opiniones después de haber probado el producto por lo menos unas semanas, porque muchos apenas lo reciben y reseñan inmediatamente sin haber probado primero el desempeño de este por un tiempo, ya sea días, semanas o meses si es necesario pues obviamente casi todos los productos en los primeros días funcionarán bien pero ya con un poco de uso es que presentan sus deficiencias o fallas y eso es lo que al comprador le interesa saber.Bueno espero les haya servido y reseñen mejor sus productos para así ayudarnos todos!⭕️ SOBRE EL PRODUCTOPues se dicen varios profesionales de la industria, las Lexar están entre las mejores y recomendadas. A mi en lo personal no me ha presentado fallas a más de un año de que la compré.Lo que si es que el plástico se ve como un poquito delgado que si la doblas parece que se va a abrir, como que no esta bien ensamblada supongo, pero creo que estará bien siempre y cuando la cuides y no la traigas en las bolsas del pantalón o algo así.These are not genuine Lexar cards. They are fakes from Taiwan after Lexar sold out to some BS company in Shenzhen. I shot dual slots on 4 cards for a wedding this weekend, the cards are not readable after the fact on my macbook pro, air, imac, or ipad. I had to run file recovery on all 4 cards, then import tethered through Lightroom. Took me 4 hours and I almost lost the entire wedding shoot. Could have cost me 10k in insurance. DO NOT BUY THESE. THEY ARE FAKE!!!!! I SHOULD SUE OVER THIS, I COULD HAVE RUINED A CUSTOMER'S WEDDING AND RUINED MY REPUTATION!!!!
