¹ Speed may vary for devices that do not support UHS-I due to different interface requirements. ² The 512, 256, 128 and 64 GB SD memory cards support 4K UHD video recording. Compatibility may vary depending on the host device. ³ The read and write speeds quoted are based on internal tests carried out under controlled conditions. Actual speeds may vary depending on card capacity. The stated performance was achieved by using PRO Ultimate SD memory cards with Samsung readers.

⁵ 1 GB = 1,000,000,000 bytes. Some capacity may be used for system files and maintenance, so actual capacity may vary. ⁵ Test device: Sony Alpha 1.

  1. Peter

    This card fits my camera needs perfectly. Great quality from a trusted brand and fast enough to cope with stills and video.

  2. Andy

    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

  3. Ash

    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!

  4. Richard Stevenson

    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.

    Was opzoek naar een snelle kaart voor in mijn Roland SP 404 MK2 en deze werkt perfect! De samples laden snel en op schrijven de backups snel naar de kaart toe. Ik ben gegaan voor deze kaart omdat hier 10 jaar garantie opzit dus laten we hopen dat het een tijd meegaat.

  7. Attilio

    Veloce , non fa collo di bottiglia negli scatti a raffica in raw , veloce nel trasferire file al pc

  8. Microotje

    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.

  9. Matthieu

    Prix super résonnable, et performances irréprochables qui sont réellement atteintes en écriture (ce qui n’était pas le cas avec mon ancienne sandisk extreme pro, bien en deça des chiffres annoncés).


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