Samsung EVO 64GB 48/MB/s Micro SDXC Memory Card with Adapter up to (MB-MP64DA/AM)

I tend to do a very large amount of research before I buy anything tech/electronic wise since I not only find it fun but of course helps me end up with the best product for the money, future proofing to the best I can and also not over spending on features that go used(which in the case of SD and memory cards is a big issue)I now have it in my Samsung Galaxy Note 4, and primarily got it because I stream via ChromeCast/Samsung TV 1080p movies frequently approx 2GB each. I want to free as much space on my internal memory as possible so as to not slow the device down with large movie files like I was doing with the old class 2 16GB card I had.Now as this card totes a Class 10 transfer speed rating that is also UHS-1 compatible....the kicker, if your device supports UHS-1 and by the way no smartphones at the moment do...and unless your using your phone as a professional video camera, recording large HD clips it makes no difference really and this is why UHS-1 support if found mainly on high end video recorders. So the advertising for this card boasts a 48m/s transfer speed that sounds pretty good right? (dont forget this says "with UHS-1")....Yes you see where now one can be confused about the real speeds people will see on their smartphones/tablets, which by the way is probably the majority use now of these cards as one can now add double their 32GB internal memory in one fast SD card for about $30...kind of makes you think how much of a rip off Apple is for charging 100 bucks for each additional 16Gbs or 32Gbs, I mean the physical memory isnt costing them that so what is, memory started becoming dirt cheap about 6 years ago but drones still cling onto their iphones like something called Micro SD cards havent been invented. Oh I forgot they have "the clould" because that is like exactly the same thing as having the data on a memory card in your phone, not dependent on Apples servers or data/internet being used or even present . Anyways enough icrap, this is the EVO version, the mid range model, the PRO being the best but also exponentially more expensive...the EVO was only about 10 or 15 bucks more than the baseline card and is about double the speeds. The PRO version had about double the EVO speeds but I was almost sure those added speeds wouldnt get utilized on my phone...I couldn't find anywhere detailing exactly how fast the Note 4s SD hardware/software was capable of transferring but since the Note 4 is essentially the top of the line phone toting the most up to date processor and other specs I figured that it had to at least transfer Class 10 speeds.So far I am extremely happy with the performance of this card. Besides the plethora of great reviews about this card which makes pulling the trigger way easier on the order. I like the Samsung Samsung paring haha as hey it can't only help right?...BUT now let's get down to real stuff...HOW DID THE CARD ACTUALLY PREFORM WHEN TESTED? (Using the A1 SD Bench app which is a great app to test your phones SD card but also see how other phones on the market, tablets, and their specs stack up against each other) This is an awesome app because the data is all sourced from the very large amount of tests that people who run the app submit for all to see, so the numbers are real world sourced, have a large sample size to null any outliers, and doesn't have a bias towards hyping certain features like advertising does.The card averaged over over 10 tests of the long test mode (recommend standard):40.95MB/s Read ------ 20.92 MB/s WriteSo it seems that although the toted 48 mb/s they advertised, with UHS 1 compatible device if you pay attention though...which my Note 4 is not compatible with...still hit consistently at 40/20 read write with the card about 3/4 full of content during testing as to test real life conditions. The Note 4 does appear to support Class 10 transfer speeds on SD cards and this card works great because you are not over spending on anymore than you need, yet your utilizing the cards EVO speeds practically fully when tested in real world conditions.

I have been using this in an LG GPad now for three years without any issues. I wasn't certain that the LG GPad would be compatible with the XC 1 memory but it was not an issue.This is a decent card, though compared with modern options such as the new U3 version of this same card, it falls short in performance. Read speeds were about 42MB/s and writes at 22MB/s. This card works well in my tablet and would do well for most cell phones. Use in cameras should be fine as well as Full HD video. However, performance falls short of the mark needed for recording 4k video.Compared with the Sandisk Extremehttp://amzn.to/2tbR1jgThe Sandisk Extreme has about 2x read speeds, but write speeds 3x faster than the Samsung Evo, bringing it within range for 4k video recording. The SanDisk is a more expensive card, and worth the price. If your are truly on a budget, and do not need to record 4k video, the Samsung may be acceptable.Compared with Sandisk Extreme Pro XC Ihttp://amzn.to/2sad8b7The Samsung Evo half as fast as the Extreme Pro in reads, and does compare when it comes to writes speed. The Sandisk Extreme Pro XC I is 4x as fast, though much more expensive. This Sandisk Extreme Pro is more comparable to the new U3 version of the Samsung Evo, a card with a similar price to this one but much better promised performance.Samsung Evo U3http://amzn.to/2s0xS2tCompared with Sandisk Extreme Pro XC IIhttp://amzn.to/2tb5GedThere is no comparison in performance. The Extreme Pro XC II is rated at 300MB/s vs the 42MB/s read speed for Samsung Evo U1. The read speed difference may be worth the additional money in some situations, but the cost is also about significantly higher.Dumping a large amount of video files off of this card would be a chore. I do recommend removing it from the device for best performance, and using a quality card reader such as.http://amzn.to/2shF9Ouorhttp://amzn.to/2shRWAzI have attached a benchmark using the Saicoo reader above and a generic USB2 card reader. The transfer rates using the Saicoo show this card to operate at specified rates, about 42MB/s read and 22MB/s write. A good card for the money but definitely a budget card. Even when plugged into a USB 2 port, the Saicoo transferred at 40MB/s, a definite improvement over a bundled generic reader.

It works as expected. Placed in my Samsung Galaxy Note 4, came to something like 59GB or something, which is expected, because of formating. Go out and buy a 6TB hard drive, and your not going to get 6TB, not even close. Just saying. As for the speed, I've upgraded from an old SanDisk Class 4, to this MicroSDXC Class 10 Samsung EVO. I was recording 48Mbps 4K videos with my Note 4, and when it came time to end the video, and the phone would process the videos, it would take FOREVER. So I said let me get a new one, they're pretty cheap nowadays, several months latter, I got one.Why several months latter, because I don't really care about getting a memory card. That's why. I have plenty of money, and I honestly didn't really need one. There's needs, then there's wants. This was a want. I wanted a new card, so I purchased one when I felt like it. It does work much better when processing the 48Mbps 4K videos. When I would record a 10 minute video, it would take like 30 minutes to process. Now it takes about a couple minutes, if that. I was thinking of going with an even faster card, but again, it's a want, and this is fine for what I was looking for. It works. I also use it to make back ups of my apk files, and I also use it to do back ups using TWRP Recovery. Yes, my $700 phone is rooted. I also use it with "not available on Google Play" SCN Recorder Pro 1.0.2, which records the phone, for crap like Clash of clans, etc. etc. Records Internal Audio, and records video at 30Mbps. The quality of my videos is probably better than anyone else sharing they're defense and attack videos on Clash of Clans. Clash of clans is a game, but I've spent at least $150 so far on Gems alone, to get a jump on the game. Anyways, it's a decent card, and I gave it five stars.
