PNY 128GB Elite-X Class 10 U3 V30 microSDXC Flash Memory Card - 100MB/s, Class 10, U3, V30, A1, 4K UHD, Full HD, UHS-I, microSD

MicroSD cards are one of those components where going cheap has a way of costing you more in the long run, either through data loss, slow transfer speeds that bottleneck your workflow, or cards that fail prematurely under write intensive use like continuous recording. The PNY 64GB Elite-X Class 10 U3 V30 microSDXC 3 pack hit the right balance of specs, reliability, and price for my use case and I have been running these cards across multiple devices without any performance or reliability issues. The spec sheet on these cards is worth unpacking because the rating system for microSD cards can be confusing. Class 10 indicates a minimum write speed of 10MB per second, U3 indicates a minimum sequential write speed of 30MB per second for UHS applications, and V30 is the video speed class rating that also ensures a minimum 30MB per second sustained write performance during video recording. That V30 rating is the critical one for anyone planning to record 4K video because 4K footage generates sustained write demands that slower cards simply cannot keep up with. Dropped frames, recording interruptions, and corrupt video files are the failure modes you get with underspecified cards in demanding recording applications. I deployed these cards in a mix of applications including a dash cam running continuous recording cycles, a security camera that writes consistently over extended periods, and a tablet as expanded storage for media and app data. All three use cases have run without interruption and the cards have not generated any error messages or performance warnings across weeks of continuous operation. Transfer speeds when moving files to a computer via a USB 3 card reader are fast enough to handle batch transfers of large video files without becoming a bottleneck in the workflow. Reading through hundreds of photos or moving multi gigabyte video files completes in reasonable time and the rated 100MB per second read speed translates into real world performance that matches the specification. The 3 pack format is the most practical way to buy these for anyone who needs cards for multiple devices. Having three matched cards means you know the performance characteristics are consistent across all three and you have a spare ready if one card needs to be replaced or is in use for file transfer. Buying one card at a time for multiple devices adds up quickly and the 3 pack pricing represents meaningful savings. For high capacity, high speed microSD storage at a price point that makes it practical to equip multiple devices simultaneously, the PNY 64GB Elite-X 3 pack delivers exactly what the specifications promise and the reliability over extended use has been solid. These cards are performing exactly as expected across demanding continuous recording and general storage applications.

cartão muito bom, produto original, o meu não bateu uma velocidade tão alta creio que por conta do meu leitor de cartão, no celular deve bater a velocidade descrita

Not much to say about this except that it has given no problems yet. I've been running a few of these in 4K cameras to act as a DVR cache, and a few weeks in, no problems yet. If I have a problem, I'll be sure to report back.

Aucun souci, matériel reconnu, pour l'instant je l'utilise quotidiennement sans ennui particulier depuis des semaines.

Gut und sehr zufrieden
