I have a five-year-old LG V60 ThinQ 5G. The best phone ever made. If you know you know. It has an SD card slot, Quad-dac, headphone jack, large screen & does everything I need it to. Mine came with a dual screen case in 2020. I thought I was big time with my 64GB Card but my phone was starting to get cramped. There's a right way & a wrong way copy your phone's SD card, if you are lucky enough to have a phone with an SD card slot. Phone manufacturers are going in the wrong direction I make music for a living and work with a lot of people that are technically savvy and knowledgeable about technology. I can't remember the last time I spoke to someone who was excited about their new phone. If you're upgrading a phone's SD card, Installation isn't hassle free but it's not difficult, just time consuming. Especially if you're moving From a smaller card to a larger one. In my case, I couldn't simply clone the card. I ended up doing a copy/paste transfer using my studios desktop. I'm using the phone now. I was able to free up a bunch of internal storage & have it set to save new files on the new card. I have a ton of space now but the process wasn't painless and it took more time than I would've liked. But that had nothing to do with the card itself. Phone is working great with the new card SanDisk makes high quality SD cards I could have went with an A2 card but I'm not recording 4K video in this particular card worked perfectly for 5 years so why mess with perfection right. This card's design is meant for basic everyday storage and backup it's not the SD card you want if you are shooting high-resolution 4K video and all that. But it's the perfect card for what I needed which is phone storage now I have a lot of it I have a couple dozen of these cards. I use them in my MPC & for transferring files to Serato DJ Pro. If you're looking for a solid SD card that will just work, this is it. This isn't the fastest SD card but it's reliable. I probably have about 20 of these and have never had one fail. 5/5

Very fast read/write speeds. I own several of these for my security cameras and doorbell camera. I've never had any an issue with any of them some of which I have been using for 7 years straight. I'm not sure what the lifespan is on these but I've yet to meet it. Great value for your money and reliable.

This is pretty slow storage in 2025, but it is to be expected as it is the low end class card. No where near the advertised peaks except for brief moments in specific use cases, which I guess allows them to advertise it, but don't expect sustained reads or writes at the advertised speeds. All in all it is functional and a very modest price especially at the 1.5tb size I purchased. Would buy again if I wanted large storage that doesn't require significant speed, which is what I needed it for and am satisfied with the purchase in general.
