💾 Silicon Power 128GB Superior Pro Micro SDXC UHS-II (U3) V90 8K High Speed MicroSD Card with Adapter - Compatible with GoPro 8 GoPro 9, R/W up to 290/160MB/s Review

I tested this card's UHS-I speed on USB 3.0 using AJA and CrystalDiskMark. Write speed was a terrible 34MB/s, and read - 36MB/s. This is rubbish, not recommended, will crash any device that needs UHD, 4K, etc.

This brand is V90 8k compliant and has proven reliable after 2 weeks use. I keep wondering why my videos aren't high quality. This high writing speed is essential for 8k video recording and high-resolution still image recording!

Problem: Getting the new Samsung GalaxyS20 Note 5G to record directly to the micro SD card. I tried 4 high quality micro SD cards and they were all registered for 8k recording. I'm sad to have to change my report that the chip didn't record 8k on the new Galaxy S20note ultra 5g. It looks like this phone is not designed to write to the SD card.

I wrote a bad review and was going to return it but it turned out the adapter I was using was defective. I further tested this card on my laptop, which has a direct connection without an adapter. The speeds were MUCH faster. Those weren't quite the speeds promised, but it's definitely close enough to be considered a v90. Hold this card. Thanks also for the great price!

In my Dell 5285 tablet, this 128GB UHS-ii SD card tested the following speeds: 240MB/s read, 135MB/s write, very close to the advertised speeds. Speed may increase/decrease depending on the device and type of files being transferred. There are slower cards with more storage for the same price, but I needed fast read/write speeds to transfer large photo files. This card was cheaper for me than the more expensive v90 cards. I don't make videos so I can't comment on the quality of the video. I've…

I am using this micro SD card on my Asus Zenfone 5z ZS620KL Android smartphone. (It also works on my Ubuntu Linux and is exfat formatted). Good size for the price and speed. When the micro SD card in my phone copies a file from my Linux PC to the phone, the fastest I've seen is 110MB/d, but not often. Most of the time, the speed does not exceed 98 MB/s. Now some of you might think this isn't fast enough. I've learned that if you need speed on a micro SD card, you have to pay for it. Best. As…
