Lexar 256GB High-Performance 633x UHS-I microSDXC Memory Card with SD Adapter

Seems to work great, I have had no issues with it since installation. It was slightly difficult to install it into the space provided in my phone, even though this was done by the store "expert," and it took 3 attempts. The total time was only 5 minutes maybe though, so no big deal really, but a novice might have had a harder time. This could have been due to the design of my phone though, I'm not certain. Otherwise, completely happy with it so far.

So far, so good. My phone was being wonky. Russell and William at the Newton "Connect Store" were terrific. Got my phone back and running in tiptop shape. Can't say enough about how Great it is to have Russell and William on the Job. Thank-You.

into our Tapo H200 storage hub which quickly formatted the disc for picture storage.I would not have been able to complete this purchase without the great help I always get from the Bellevue, WA store. Thanks!
I've tested 2 of these cards. My computer reads the card at ~460 GB. This translates to ~482 GB if you're using the 1000000 bytes is a gigabyte. Either way it's 30GB less than 512GB (about 5%) what you're paying for. It's effective read and write speeds are significantly slower than cards that are advertised even slower. For larger 5GB file writes expect failures (mostly video). Reads are just as bad. It is super cheap $75 at the time and the next 512gb card is $100. Expect to get what you pay for.
Walked into the store in a hurry. Needed portable storage of 256. Manager recognized me. Led me right to it. We thanked each other and parted ways. Happens all the time.
I had and older laptop and it was beginning tp fail.I'm 78 and I have pictures going all the way back to 1942 that I've spent countlesshundred's of hours scanning and touching up adding times names and dates. I evenhave a picture of my loving wife of 56 years on the night we first met July 10th 1957.They require a lot of storage space and I have eight USD sticks full. It was difficultwith the old laptop hanging up but I stuck with it and with the high capacity "Lexar"chips I was able to load everything on to a single chip and make a second chip back-up.There are other back-up sites but I would highly recommend "Lexar" for reliablestorage of irreplaceable family photo files as they require a lot of storage space.
I bought 2 of these cards a little over 2 years ago. Each went into a Galaxy S10 phone, mine and my wife's phones. With hers, we had a mysterious disappearance of her entire photo album about 12-18 months later. I pulled the card, bought recovery software and managed to recover some photos. We thought it was a fluke, maybe the toddler accidentally deleted the entire album or something. Today, about 26 months after purchase, my card in my phone did the same thing. 2 cards, 2 devices, 2 failures, in 2 years. Absolutely unacceptable. I may never buy Lexar again.
I've used this brand before. At first I was sceptical. I've been using San Disk for years. I'm glad I tried Lexar. As far as I'm concerned it's a toss up between both cards. Thank you Lexar. Thank you B&H.
I know the tech was injured and working hard, and Daniel is very good, he cares, and helps. He tried to transfer all my existing pictures/videos to the new SD card, but only a few copied over. I hope the originals are still on the old, full card. I will bring it and let them try again
