NOT CHEAP, but BEST for massive storage, speed & longevity it apparently has — in MY OPINION….
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?

Samsung always pleases with their sim cards!!
I purchased this sim card for my Samsung phone. Excellent quality and great value. I’m able to store my photos on the sim card and the picture quality was not compromised. The sound quality is great as I listen to a lot of dj sets when I’m out and about. Highly recommend this product. Cool design and it’s durable. Cheers!!!

Easy and fast
Got this SD card for my security camera. Love that it has a lot of storage space. I was going to order a generic Amazon brand but was worried the transfer speed wouldn’t be fast enough so I spent the extra couple of dollars to get this one and am absolutely pleased with it. It came with an adapter so I can look up the videos on my computer and haven’t had an issues. Formatting was easy and had no problems at all. I have another one in my switch and works just as good as the other big name brands for a fraction of the price. Do recommend

No problems. Fast and reliable
I purchased this card for use in my dash cam (Peztio Anyski-M5). I wanted enough space to handle 3-channels (front, rear, and interior) for an extended period of time.This card works perfectly. No issues with speed and has been reliable in the camera. Excellent price for 256GB.

I use this permanently in my lenovo laptop as a additional storage to my internal ssd. It’s great. Fast enough for all the downloads and archive pics and documents.

Ya tiene tiempo que la copmre y sigue funcionando perfectamente, tengo una en una consola y otra en una cámara de accion, en ambos casos siguen funcionando sin problemas la recomiendo por completo

Good capacity and quick load
