Patriot Memory 64GB EP A1/V30 Micro SD Card,Android Phones,Tablets,4K

Claimed Specs vs. Physical Daily Reality: Advertised as a standard 64GB UHS-I flash memory card. Physical testing on an Ubuntu Linux environment using it on SD card slot on an MS Surface Book 2, reveals a genuine usable formatted capacity of 56.31 GiB with zero corrupted or missing sectors out of the box. 📊 Sustained Write & Read Endurance: Tested under an intensive continuous 24-hour diagnostic soak loop using f3write and f3read. The card successfully completed 45 full write/read passes—transferring over 2.5 TB of aggregate data—with zero dropped blocks, write errors, or controller hangs. ⚡ Bus Saturation & Thermal Behavior: Sequential read performance peaked at 92.95 MB/s, effectively saturating standard UHS-I bus throughput limits. Sustained write speeds held steady between 43 MB/s and 66 MB/s across full capacity fills without severe thermal throttling over extended operations. 🌡️ Operating System Readiness: Ideal for single-board computers (like Raspberry Pi), custom OS builds, and retro emulation setups requiring steady read speeds and consistent thermal endurance. Depeding on the revsion on those devices, this SD card is great fit to match what the device can achive.🖥️ Consistent Cadence: Maintained a remarkably stable execution loop during stress testing, averaging roughly 32 to 33 minutes per full 56.31 GiB cycle. ⏱️ Plug-and-Play Reliability: Formatted without errors and immediately ready for deep diagnostic validation or active deployment as a boot/storage drive. 🔌 UHS-I Write Floor: While perfectly suited for everyday computing, emulation, and OS deployment, the sustained write floor of ~43 MB/s during massive multi-gigabyte transfers sits below high-end V30/U3 rated flash media. 📉 Heavy Sequential Ingestion Limit: Users looking to write massive 4K video feeds directly to the card may find the write ceiling limiting compared to faster specialized cards. 📽️ Workflow Impact: This drive delivers exceptional price-to-performance stability for secondary storage, system backups, and continuous embedded workloads. It withstands continuous thermal cycles without memory degradation, making it a fully qualified, highly dependable choice for active home lab setups and everyday storage expansion. 🎯

bought this Patriot 64GB Micro SD card for expanded storage, and it has performed flawlessly. With its V30 and A1 speed ratings, it handles high-resolution 4K video recording smoothly without any dropping frames or lag, and apps load quickly without freezing. Transferring files to my computer is fast, and the 64GB capacity offers plenty of room for photos, videos, and music. It came formatted and ready to use right out of the packaging. If you need reliable, high-speed performance for your phone, camera, or Nintendo Switch at a fair price, this card is a great choice!

Ordered for my Wyze camera, works great. Good deal and shipped quick.

I have bought several of this micro SD cards. In general, they work well, but when shooting video, they would stop recording several times and it would take a while for the card to store the video properly. Although I properly reformat the cards every single time I load them in the camera again, part of the storage space seems to still have some data which I can't either erase not access to read. This is true with every single one of them. Not sure what is going on.

I've purchased 8 of these. I've had 1 of them fail within the first 30 days. Otherwise, they work great. I like the value for the price so far.

Great for the price. I don't use fancy camera equipment so I had no issues for what I use it for.

dependable

When formatting to use, it would not reach 100%. After 8 tries, I can only get 58GB of the 64GB for use. POOR STORAGE CAPACITY. FAULTY recognition - took 3 tries before device could recognize the card. All round, not impressed. But at the price paid it will have to work.

I bought this 2-pack of Patriot 128GB microSD cards specifically for my CCTV cameras, and so far they’ve been completely reliable. First impressions were good — they feel like decent quality cards, not cheap or flimsy. I’ve had issues in the past with other budget brands where devices wouldn’t even recognise the card, but that wasn’t the case here. Both cards were detected straight away and worked without any problems after a quick format. In terms of performance, they’ve been solid. I haven’t experienced any lag, errors, or data corruption, which is exactly what you want for something like CCTV where reliability is important. Recording has been smooth and consistent with no issues so far. Storage-wise, I got around 116GB usable space, which is pretty normal and expected — you never really get the full advertised capacity, so no surprises there. The fact that it comes as a 2-pack was ideal for me since I needed cards for two cameras, and it works out well in terms of value. For the price, I think they’re definitely worth it. I’ve been using them for about a month now and haven’t come across any downsides so far. Overall, they’ve done exactly what I needed them to do without any hassle.

I received this 128 GB Patriot Micro SDXC card yesterday and then I immediately tested it in my Macbook using h2w test program for checking the storage capacity and average write and read speeds. The test results were all good and the storage capacity is correct as stated (nearly 128 GB as marked on the card, 125.07 GB as reported by Mac Disk Utility and a Free Space of GB 116.48 as reported by h2w test progaram) and is acceptable. The average write speed is 18.9 MB/sec and the average read speed is 90.73 MB/sec. I am using it for Video Storage from a indoor survaillance camara and installed it in a Home Hub. This card is now working good in the Camera / Hub as expected. I chose this Patriot brand after having a bad experience of receiving a fake card of Sandisk brand from CLICKTECH RETAIL PRIVATE LIMITED sold on Amazon.in. The problem of the fake Sandisk card is storage capacity. It is marked as 256GB but is actually only 32GB and that too failed in 6 months of usage. I do not know the longetivity of this card as yet but I can say it is value for money as compared to other brands.

Väldig bra kvalitet.

Just received them. Working great. Let's hope they last.

Amazing memory stick. Transferring datas, pictures and videos very faster, I have used other brands but this tiny stick was fantastic highly recommend for your electronic gagets.
