SAMSUNG EVO Select microSDMemory Card + Adapter, 512GB microSDXC, Up-to 160 MB/s, 4K UHD, UHS-I, C10, U3, V30, A2, for Mobile Phone, Smartphones, Nintendo-Switch, and Tablets (MB-ME512SA/AM)

I bought this Samsung EVO Select 128GB microSDXC card to replace an older SanDisk card I had been using — one that originally came from a Nintendo Switch. I was using it in a modded iPod, and I kept running into freezing or lag whenever I skipped songs or moved quickly through menus. Super frustrating.Since switching to this Samsung card, the difference has been night and day. Everything is smooth now — no more freezing, no lag, just fast and reliable performance. Song changes are instant, and the iPod feels snappy again.The card came with an adapter, which worked flawlessly. It was plug-and-play, and my iPod recognized it right away after formatting. I’ve been using it several times a day for a week now, and it’s been rock-solid.If you're using flash storage in a music player or similar device and running into issues with an older or slower card, this Samsung EVO Select is 100% worth the upgrade. It solved all my problems. Highly recommended.

I’ve been using the SAMSUNG EVO Select microSD card for a few months now, and it has exceeded all my expectations. I bought it for my GoPro 11 to record YouTube videos and no issues at all.What I love:✅ Speed – Transfers are lightning-fast. I move large video files and high-res photos all the time, and this card handles them without breaking a sweat. Apps also load quickly when stored on the card.✅ Reliability – No data corruption, no glitches, and it’s been through a lot—heat, travel, and even a bit of water. Still going strong.✅ Capacity – Tons of space. I’ve loaded movies, music, photos, and games and haven’t come close to filling it up.✅ Price – For the performance and capacity, this card is a steal. I’ve paid more in the past for cards that didn’t perform half as well.If you need dependable, high-performance storage for your phone, camera, or console, look no further. Samsung nailed it with this one. Highly recommended!

I've used and tested several brands, and my personal opinion is that this SAMSUNG, although more expensive, is best for massive storage.....again, in MY opinion. Good luck to you.Like all memory products, it starts out expensive (~$50+), and just keeps getting cheaper.....and that's great for all of us. But I also like the many bytes I can record or transfer very quickly. That pertains to all manner of stuff, including 4K video. That's what I use it for, and so far I've acquired more than six of these 512 Gb USB's and I can't blame a single one for causing a major error. I keep looking for them, but there's been nothing that I can blame the device for. Knock on wood....and the fact they keep getting cheaper is pretty good too. When you duplicate as many bytes as I have, back and forth sometimes (I don't like fragmented files), and the byte count is still always exact -- for half a Terabyte, that's really good. I'm old school....but ain't digital great? I remember trying to do this 50 years ago (YES!) with analog.....and I was consequently very sad, a lot.NOTE: All's good, but to be specific, I really like the PRO version with the connected USB. That's great. And, I also re-format in NTFS...all I want is the memory for remote portable drive use. That's ME. That's all I want to say.--> all for NOW, that is. I have finally noticed how HOT these little 1 Tb guys really are......can't keep your finger on them when they're working and recording so fastI'm not saying this as a FINAL condemnation, because it MIGHT even be within tolerance for this thing. However, if it's ONE thing that I've learned after 38 years experience in electronics, it's that HEAT ultimately kills most failed electrical devices, big & small. I started with audio repair, and ended with programming excalibur and other fuze stuff for ARL. HEAT kills, sure, but I still will admit that it may not be so conclusive, after all. I've gotten more than 10 of these things and so far, they've worked very well, even ALMOST perfect, I must admit....NO MORE than a few bytes altered during transfer, with absolutely NO failure noted (I'm told by a computer repair owner that the memory will work flawlessly for a time, and ultimately will just give out all of a sudden--answer, use BACKUP! ).....but, I'm still thinking of clip-leading a little fan to come on every time I apply power to a circuit, or, maybe even getting a tiny little heat sink. I don't know. But I'm sure going to continue testing these things out......just be aware that 'heat kills', period. (I have to concede one thing....I haven't seen a failure yet, hot or not)MORE....Oct 24, 2024.....yes, it's more. And not a single failure with many hours of transferring, reading & writing ---with over a dozen of these big memories (1/2 & ONE Terabytes) being used a great deal, I cannot recall a single failure that was the chip's doing. Hot, yes, but NO failures. And, at most, while transferring a TeraByte of data, fragmented or otherwise, the most difference in the whole lot was no more a few bytes....and I kinda laughed that off. No problem. Also, last year I mentioned the 'defragging' of the memory during a 1Tb-to-1Tb session. I had a terribly fragmented chip that I transferred (yesterday), and it took about 3 1/2 hours, give or take, and AGAIN showed about 25 GigaBytes MORE memory available after the transfer for the new chip, with identical memory capacities on both. This is about what I reported before, so with the accuracy & acceptable speed (for me) the de-fragging effect made the copy faster by reading/writing faster afterwards, along with greater accuracy, now being sequencial..... if you can believe that. Thank progress for digital technology, because I remember the analog days very well. Same data, but much, much different results.By the way, the KEY to digital accuracy is called 'handshaking'', whereby at the eol (end-of-line) the byte-count is compared before advancing and denoting an ERROR if it is not the same. Other than that, it's just SPEED, which just keeps going up and up……the Japanese have affirmed, with cost no issue, that the internet could transfer 1000 movies per second, if they are correct, and I believe they are.FINAL edit....Dec 22, 2024.....This is so long now, I might as well add something I left out......the reason digital is mostly 'more accurate' than analog is primarily due to something called 'handshaking'', whereby at the eol (end-of-line) the byte-count is compared before advancing and denoting an ERROR if it is not identical. Other than that, it's just SPEED, which just keeps going up and up in digital land……the Japanese have affirmed, with COST no issue for conductors, that the INTERNET could transfer in the neighborhood of ~1000 movies per second, if they are correct, and I believe they are. Have you ever wondered why streaming seems to work so well?

Every SD card I tried wouldn't allow me to store everything I have on my phone and I tried every size there was, trying to save money (when I would've saved a lot more if I had just bought this one in the first place). This card cost the least for the 1TB and everything went onto it without a problem. I'm happy with the purchase and would recommend anyone wrestling with sizes that are smaller in SD cards to just go and buy this one and get stuff stored and not have to concern themselves with files being to big and get it done hassle free.

In the previous year, I ordered one of these thinking it was official (no it wasn't) probably because I was on the wrong page. I ordered this one (from the correct page) back in November, and I'm glad to say it actually worked. Good storage and speed for my Nintendo Switch. It is also normal for larger capacity storage devices to have a few gigs knocked down, nothing to tweak about. If memory serves right, the 512GB card came at around 450-480GB, which at that point I didn't mind, since Nintendo Switch games don't take much storage anyway. Mine didn't arrive broken either, and it's still kicking.Overall, a great MicroSD card that can do what its supposed to do.

Galaxy A15 5g did NOT recognize the micro SD card when it was first inserted. I tried restarting the phone several times. A15 still did not recognize it. So I inserted the SD card into an external card reader and connected it to the phone, using USB -C cable. A15 recognized the card, and asked if I wanted to format it, which I did. Afterwards, I re-inserted it into a SIM card slot, and everything worked just fine. Very fast access time. So, format it somehow before inserting it into the SIM card slot.
