PNY 256GB Elite-X Class 10 U3 V30 microSDXC Flash Memory Card - 100MB/s, Class 10, U3, V30, A1, 4K UHD, Full HD, UHS-I, Micro SD

This SDXC card really scared me at first. I bought it to use with Arduino and Raspberry PI projects. I switched my computers over to Linux Mint XFCE lately, and am mostly loving the difference! When I went to format these SDXC cards, they were not showing up as 64GB. They were showing up as like 1GB best I can remember. I though maybe it was a problem with my Linux setup. After several hours of trial and error, it turns out that the SD reader in my computer was too old to read SDXC cards. I had a new SD reader on a computer in my shop with the same Linux Mint XFCE set up. It worked flawlessly with the new reader. So to sum things up, If you have an old SD card reader, you may need to get a newer one if yours is having problems supporting these newer SD cards. The old reader I had was probably 25 years old and did not support newer SD card formats. Other than all that, I have always bought the PNY brand due to good service, reliability and price! PNY beats them all for quality and value! I don't even consider no name brands or over priced name brands anymore! I filter my searches to only show PNY. Off brands are not much cheaper if any. Other big name brands want to charge double for a product that isn't any better! Stick with PNY! You won't be sorry!

Reliable 4K recording and fast transfers ✔️ Smooth 4K video recording ✔️ Fast, consistent file transfers ✔️ Class 10 / U3 / V30 / A1 rated ✔️ Works across multiple devices ✔️ Includes adapter ✔️ Strong price‑to‑performance I’m using this in an AKASO Brave 4 Pro and it’s been flawless. It formatted quickly, records 4K video without buffering or dropped frames, and has plenty of space for long sessions without swapping cards. Transfers to my PC are fast and consistent. I tested the card through my normal setup, an Anker 675 dock connected through an 8‑foot USB‑C extension, and it still delivered the expected UHS‑I speeds (around 79 MB/s read and 49 MB/s write). Since SSDs hit full speed on the same setup, it confirms there’s no bottleneck in the hub or cable; the card is simply performing exactly where a V30 microSD should. The included adapter makes it easy to use in standard SD slots, and the card’s ratings (U3, V30, A1) make it suitable not just for action cams, but also for phones, drones, and dashcams. For the price, it performs just as well as more expensive brands. A solid, reliable card for any device that needs smooth 4K recording.

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.

I bought these to use with my Wyze security cameras. Works well with my units and easy to install. So far, no complaints.

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

Produto ok

Great SD, it lasted 2 years before it started having issues with my dashcam
