To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
I got this for my mom for her birthday. I helped her put music on her cell phone, but ran out of storage from the main phone itself a month or two ago (she isn't tech savvy enough to do streaming music). I was a little leery since this card is a lot less expensive than what I've paid for others in the past, but I checked it on my phone before giving it to her as a present and it worked perfectly in my phone and in hers. I haven't completely filled it up, but it seems to be the genuine amount of storage it claims to be and we haven't had any issues with the phone accessing music or it being slow to transfer files.
I bought it for a game console. Speed is good, price is acceptable, so far no problem. Maybe is not the best choice from memory size, but from the price side, it has a good value. I think the capacity would be enough at least for a couple of years to use moderately. Of course ever onece a while you need to delete your unwanted data or transfer them to another space, which is fine to me.
This device has good performance for the price. gnome-disk reported read speeds up to ~94 MB/s, and write speeds around 22.6 MB/s . When writing the raspberry pi image the card, I saw speeds closer to 5 MB/s writes, your mileage may vary.
I'm attaching the benchmarks from gnome-disks uility. Overall, I'm satisfied with the value.
For safety against malware, I always first format (FAT32) a drive. Initially, both of these cards appeared to 'hang-up', but secondary attempts successfully formatted. Saw a few negative reviews based on device compatibility, but I tested (h2testw) fine on both Lenovo ThinkPad (Win10) and BeeLink GS-1 (Android 7.1): read 24GB/s write 16GB/s.
The amount of memory for 10.99 is very reasonable. My Amazon Fire 8 tablet transferred four apps and other data files amounting to 1 gigabyte. You have to be careful when inserting the card into the sd card slot. The card is offline on my music mp3 files, so I need to find out what offline means. However, the card seems to be compatible with my tablet and Samsung phone.
I’ve bought 7 over the course of 3 months. Comes within 2 days, nice packaging and warranty, used in 5 fire tablets and 2 android phones, great amount of space for the price, no problems mounting any of them.
