EVO Select Micro SD-Memory-Card + Adapter, 256GB microSDXC 130MB/s Full HD & 4K UHD, UHS-I, U3, A2, V30, Expanded Storage for Android Smartphones, Tablets, Nintendo-Switch (MB-ME256KA/AM)

512GigaBytes & 1-TeraByte SSD -- 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 a dozen of these 512 Gb & 10-1Tb , micro SSD chips and I can't blame a single one for causing a major error, although I did have one 1-Tb destroyed by a crashing hard drive--this was verified by the FORTECT internet company. I keep looking for errors, 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 it's good, not to mention a full Terabyte, extremely 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.....quite a lot. NOTE: All's good, but to be specific up to now, and I do like the PRO version with the connected small USB connector. 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, for now. --> now for an edit, 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. However, they evidently are still in tolerance. No failures. I'm not saying this is a condemnation, because it seems to be well within tolerance for this 1-Tb memory. However, if it's ONE thing that I've learned after 38-1/2 year's experience in electronics, it's that HEAT ultimately kills most failed electrical devices, big & small. I do think they've reached their limit in memory size for this 1-Tb, because the bigger memoryh would just get too hot. 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 many of these micro devices that fit on the tip of your finger and so far, they've worked extremely 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 these memory micro SSDs will work flawlessly for a time, and ultimately will just give out all of a sudden--ANSWER, use BACKUP! )..I backup all my 'valued' videos, etc...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. (however, I have to concede one thing....I haven't seen a failure yet with these micro devices, hot or not) MORE....Oct 24, 2024.....yes, here'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, probably due to late spot-editing. 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, checked by PROPERTIEs function. 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, it NOW being sequencial..... if you can believe that. Thank progress for digital technology, because I remember the analog days so very well. Same data, but much, much different results. FINAL edit....Dec 19, 2025.....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 really believe they really are. Have you ever wondered WHY streaming seems to work so well? 12/28/25: STILL GOOD. NO FAILUREs. NOTE: early 09/25 I must say--I recently GOT a FAILURE......HOWEVER, I could not blame the Samsung for SURE because later that day my hard drive crashed, and it crashed 8 more times next few weeks, and was kept in software perfect operation only by FORTECT internet scan/repair service.....I asked their opinion as to the cause of the SSD failure and their professional opinion was most likely due to the failing hard drive and a 'driver' connection with the memory. I kept the internet and machine memory running during these crashes only due to their online program software-restoration EACH time. My Conclusion: these 1-Tb SSDs are still very reliable. Not cheap, but VERY good. mjm

The EVO microSD cards are always good quality, and generally at a good price!! I usually stick to just a few brands when it comes to microSD memory, and the Samsung cards are one of those brands. They are durable, labeling is easy to read, comes with a card adaptor. They are great for action cameras, tablet memory expansion, cameras, whatever!! Havent had any issues with them. Buy with confidence!

Works perfectly with what I need it for as it works with the MX4ISO for a PS2 it detects the games haven’t had any issues with it so far and good capacity for the price.

I was in need of a large storage card for filming events that were multiple hours long. This was a great value as they are large enough at 512 gb to hold multiple hours of storage for my needs. They film great with my camera and work great. They transfer over to my MacBook with ease and speed.

Amazing product, only issue, shipping. Took a week and a half just to leave the facility. I have 1 of these cards already so I know it works well, I ordered another one and this one has been “shipping” for 2 weeks now.

This card has held up very well. I've been using it in my Samsung Tablet for awhile, and it does have the correct capacity. There were no compatibility issues, and I didn't have any problem formatting it, either. I do not notice any difference in performance when using the apps installed internally or those installed on the card. Granted I'm not doing anything that requires high performance, but it IS a Samsung. They make good products. :)

This is a good micro SD card. I've been using it for a few years in my phone and it does the job. It is pretty fast, reliable, and at the time a good price for the money.

Best card in the market! Great quality! Fast write speed! Works in all cameras and devices always! True example of you get what you pay for! For the extra money, it’s worth it! Compatibility never an issue, no corrupt files!
