Silicon Power 64GB Superior Pro Micro SDXC UHS-II (U3) - High Speed 8K Compatible SD Card for GoPro 8/9 Review

I have several NVME and other memory cards from Silicon Power, they are reliable and fast (my NVME Silicon Power is even slightly faster than my Samsung 970s). This SD card is a real V90 card (90 MB/s guaranteed = 720 Mbit/s minimum) and handles the high bit rate codecs of my cameras perfectly (GH5 at 400 Mbit/s, Eos R 4k ALL-I at 480 Mbit /s and only the tested R5 8k IPB with 680 Mbit/s). .

This brand meets the V90 8k requirements and has proven reliable after 2 weeks. 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!

I use this micro SD card on my Android smartphone "Asus Zenfone 5z ZS620KL". (It also works on my Ubuntu Linux and is formatted exfat). 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 for…

The maximum storage capacity is not very large, but the speed is definitely noticeable. I have used this card in a 4k 60hz drone and the read speed will definitely come in handy. I wish they had a budget version of 256MB or more, but other than that I have no complaints.

Tested multiple times and this is the average: Sequential Write (4MB): 30.43MB/s Sequential Read (4MB): 75.87MB/ s Random Write (4 KB): 53.01 KB/s Random Read (4 KB): 3.76 MB/s Memory Copy (4 MB): 8.72 GB/s I have 64 and 128 GB cards Bought, tested both

Problem: Force the new Samsung Galaxy S20 Note 5G to write directly to the micro SD card. I tried 4 high quality micro SD cards and they all submitted for 8k recording. Too bad I had to change my report about the chip not recording 8k on the new Galaxy S20note ultra 5g. It looks like this phone isn't designed to be written to an SD card.

I tested this card's UHS-I speeds on USB 3.0 with AJA and CrystalDiskMark - it was a horrible 34MB/s write and 36MB/s read. This is rubbish, not recommended, will crash any device that requires UHD, 4K, etc.

I wrote a bad review and wanted to return it, but it turned out that 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: Read 240MB/s, Write 135MB/s, which is very close at the specified speeds. Speed may increase/decrease depending on the device and type of files being transferred. There are slower cards with more memory 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…
