SAMSUNG EVO Select microSD Memory Card + Adapter, 64GB microSDXC, Up to 160 MB/s, UHS I, C10, U1, V10, A1, for Mobile Phone, Smartphones, Nintendo-Switch, and Tablets (MB-ME64SA/AM)

I liked that the micro-drive holds a lot of information and fit perfectly on the s9 tray. No fumbling around. It also was a good value price for Samsung quality.

I bought this for my new dash cam. It did come with a 64gb micro sd card , not a quality item. I wanted a quality card to keep these videos for posterity. Great price for 256gb for a Samsung memory card. My camera is complaining about the card being too slow for it to access. Got it to work by reformatting, losing the last week’s videos but no complaints now.

Price, capacity, and speed. These cards have worked well so far used exclusively with an Insta360 x4. There’s enough capacity for hours of recording and hundreds of photos. No issues with write speeds for 8k recording.

High performance works extremely well. Use it for expanded storage in my steam deck. Excellent easy upgrade for the cost. Asking for another for Christmas! I’m a huge fan of Samsung storage all my SSDs and microSDs are Samsung. Never any issues. High quality and the best speeds. Note for SD they limit the speeds natively but for most applications this is not the case therefore top performance metrics for Samsung are consistent across applications.

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 fast I'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.
