Samsung Memory MB-MC512GA 512 GB Evo Plus Micro SD Card with Adapter

Works perfect for my new Samsung S10

Great price for a 512gb micro SD made by Samsung. I have it in my note 10 plus and it works like a charm. Super fast 0 problems. Samsung quality.

Great price for an actual brand!

I never expected this from Amazon, but first of all the package felt a bit weird - there is no usual anti-counterfeit measures on the packaging cardboard - just plain print (its my first Samsung SD card, so Im not sure if its usual). Then I loaded it onto my Surface Pro. The capacity looks alright (doesnt need formating). Then I enabled bitlocker and started copying files onto the drive. The writing speed was poor - it was mostly around 10 MB/sec (not even close to the 90 MB/sec claimed on the package). Then after an hour or two, 50~100 GB into the progress, the speed dropped to near zero (in KB/sec range), and the computer seemed to slow down dramatically (probably waiting for the drive to respond). I tried to close down the file manager and reboot the computer. When it comes back, I can no longer access the drive... Always prompted me to type in password for the bitlocker but then frozen/dead. I tried to re-format it regardless of the encryption, but I/O error came up and prevented the re-formatting. Tried other software, too, but with no success... It was just a nightmare after wasting a whole day on this crap. Sure this is from a third-party seller (with Amazon Prime), but I picked it based on the previous good reviews. Now I dont understand if this is a fake card or just my bad luck... Will never touch this seller or Samsung SD card again. I always had good luck with SanDisk but hope they will sell larger capacity soon (the maximum is 400 GB with SanDisk at this moment).

Its an SD memory card. What more can be said?

Does what its suppose to do. Came in a sealed package reads 512 gigs actually a little less but thats expected

Good quality and nice product from Samsung

Works great i dont regret the purchase

Ive bought other SD cards before this one is one of the best got I highly recommend you to get one.

BUYER BEWARE! Had to return as the SD card was either defective or a counterfit. Kept getting repair message when card was inserted in PC, and could not read file header.
