Samsung PRO Ultimate SD card, 128 GB, UHS-I U3, Full HD & 4K UHD, 200 MB/s read, 130 MB/s write, Memory card for smartphone, Drone or action cam, MB-SY128S/WW

Bought this purely for my handheld. Works great with no noticeable loss in performance. Maybe takes a few seconds longer to load games Vs internal SSD but isn’t a huge issue.definitely recommend to expand storage for the Legion Go!

The fastest UHS-I card I have tested - maintained a steady 128MB/sec write speed over 16GB.160MB/sec read speed wasn't quite the 200MB/sec claimed but I'm perfectly satisfied (this was with the 128GB card - maybe the larger cards are faster for reading?)Recommended.I'm planning to use it as the system disk for my Raspberry Pi 5 and will update the review if there are any issues.UPDATE: when installed as the boot disk on the Pi 5 it was about the same speed as my old SanDisk Extreme Pro but its still a good card and recommended

Got this for a Raspberry Pi 5, as early benchmarks put it as among the fastest microSD cards. I wasn't disappointed, benchmarks and real world performance are excellent. The price is excellent. Can't speak for durability yet.

This review is for the 512gb full size SD Ultimate:I have grown to like Samsung cards, I have a few for my DSLR cameras and this one is for my Lenovo x270 Laptop – the x270 was a terrific ‘renewed’ purchase recently and i7 with 16gb ram but with a 256gb SSD, this 512gb pro-ultimate SD card then is to provide some storage to the x270. It offers a good solution as permanent extra storage.Previously, I had a pro-plus 512gb micro-sd card doing that job, which it did just fine, but I want the micro-sd for the Hi-Res DAP. Swapping the two cards over gave me a chance to look at the respective read/write speeds of the two cards in ‘my’ real world situation; that of copying about 100gb of various sized files to the cards.So then, copying identical 100gb various sized files from my x270 SSD to the SD card slot for each revealed that this new 512gb Ultimate full size SD card returned about 10% faster write speed overall that the 512gb Pro-plus micro-sd card [in the supplied Samsung SD adapter].So, same system, same job… the ultimate did 10% better than the pro-plus in my situation; the pro-plus micro-sd card remains an excellent choice and are generally less expensive than the also excellent Sandisk cards, which I have a few of too.On a wider note; the image attached shows the offload speed of the Ultimate using a Lexar (RW316) card reader - writing to my internal SSD. For images it's about 135MB/s, and for video files it pushes just over 150MB/s as in the image; pleasing for a UHS-i card.

Vroeger gebruikte ik vaak andere merken van de kaartjes, maar nu ik deze Samsung pro heb leren kennen wil ik niets anders meer: heel erg snel en betrouwbaar… in ALLE camera’s die ik heb.

I am using this card, I don't have any problem with this. You can go for it.

Veloce in lettura e scrittura

Je l'ai testée avec mon Fujifilm X-S10 et mon Macbook pro M1 max (avec le lecteur SD interne et un lecteur pro externe).J'obtiens un vitesse en écriture et en lecture autour de 90 mo/s ce qui est plutôt bien pour une carte UHS-I, et légèrement mieux que mes Sandisk Extreme Pro en UHS-1 (présentée comme 170M/S et vendues à un prix similaire).On sent de plus qu'elle a une bonne quantité de cache bien rapide qui impacte positivement les performances en écriture.Dans la pratique sur mon appareil photo, le cache de cette carte me permet en rafale de gagner 3 images (RAW + JPEG) par rapport à une carte Extreme Pro UHS-I de Sandisk (19 vs 16 avant ralentissement de la cadence).Aucun souci bien sûr pour enregistrer une video 4k DCI à 30 i/s en H264 avec mon appareil photo.La vitesse mesurée devrait en pratique permettre de la 8k (mon appareil ne propose pas cette résolution, donc je n'ai pas pu tester en conditions réelles).Par ailleurs Samsung est l'un des leaders pour la qualité de ses mémoires donc je n'ai aucun doute sur la fiabilité de cette carte.

Gelijk getest werkt perfect. In dji drone snel en goed. Overdracht naar pc ik mega snel. Aanrader voor dat geld.
