64 micro SD Card U3/V30/A1 with Adapter Pack of 2 Memory Cards for Home Surveillance Cameras, Hunting Cameras and Dash Cams

The K&F Concept microSDXC UHS-I memory card 64GB is supplied together with an SD card adapter in a blister pack that can be opened without frustration. In the item description, it is advertised as a UHS-I U3 card, which means it should have a write speed of at least 30 Mbytes/s.

The card and the adapter are well made, and the contacts also make a solid impression.
The card is recognized immediately by my devices and the available storage space is indicated correctly.

I ran the "H2testw" memory card test tool twice on the memory card: The card is 100 percent correct and shows no weaknesses when writing and reading the test data blocks. H2testw has a writing speed of 43.4 Mbytes/s and a reading speed of 79.3 Mbytes/s. The SpeedOut tool determined a write speed of almost 52 MB/s and a read speed of a good 84 MB/s with my Thinkpad E 15 Gen2. This means that this no-name card is extremely fast.

For further tests, I put the card in my GoPro: 4K videos are possible without restrictions and jerks. This card is more than fast enough for use in a surveillance camera or dashcam!

Considering the good writing performance, give this card 5 stars.

Conclusion:
The SD card is of high quality and for the current price of €18.99 it is okay. I am happy with it and give it a full 5 stars ⭐⭐⭐⭐⭐ for the quality.
I can only recommend it.

Before there is any confusion, I would like to point out that I only tested the memory card, not the complete camera.

Nevertheless, I installed the card in an existing camera and it works perfectly. The recordings were saved reliably and in decent quality. The capacity is very good with 64GB anyway. There are 5 stars in front of me.

The 64 GB micro SD card is supplied in the usual blister packaging, including the SD card adapter.
The promised speeds are also achieved depending on the card reader used. Of course, if you only have a USB 2.0 card reader, you won't be able to reach the specified maximum speeds. But the card can't do anything about it!
With my USB 2.0 card reader I get about 25MB/s write speed and 35MB/s read speed. Write at 45MB/s with an external USB-C 3.0 card reader and read at almost 80MB/s. (see photos)
So absolutely solid values, with which you can work quickly and reliably.
There were also no problems with the card as a recording memory in my action cams/surveillance cams. Was recognized everywhere and the recordings were clean and error-free.

Conclusion: The card does what it is supposed to do and is absolutely reliable. I've been using the card every day for 2 weeks now and haven't had any problems. A recommendation from me. In terms of price, the card is in the lower midfield.

K&F Concept microSDXC UHS-I memory card 64GB SD card + adapter (U3, V30, A1, Class 10, 4K Full HD videos, for surveillance cameras, wildlife cameras and dashcams) The micro SD card comes with an adapter packed in a blister

. The Micro SD is clean processed. The card is for use in e.g. one fast enough in a 4K wildlife camera, but not necessarily the best choice for more intense devices. Because the speed that is promised is not quite kept here. With various tests, we didn't get over 43 MB/s when writing and 81 MB/s when reading, which is not bad, but is beaten by brand manufacturers. With the currently called price of only €18.99, we only deduct one star and remain with four stars.

4 stars - the micro SD is okay, but does not quite meet the specified performance. Since the price performance is still okay, we deduct a star for the performance.

The micro SD card is supplied together with an adapter in a sturdy blister pack. The card makes a very neatly processed impression and is recognized by the PC immediately and without any problems. The memory capacity that the PC read was 62,527,176,704 B = 58.2 GB - a fairly normal value. The card is formatted in FAT32 format and can therefore be read by most devices.

With this card I'll beef up the memory of my cell phone "a little bit" - I'm satisfied...

The K&F concept micro SD memory card with 64GB memory comes in a small blister and contains an adapter for SD size in addition to the card. Of course, the card does not have a native 64GB memory formatted, but around 58GB memory. This is due to the binary conversion of the memory.

I used the memory card with a USB adapter on the PC, so it may be that other devices achieve a higher data transfer rate. In my test, I was able to transfer files to the memory card at speeds of up to 20MB/s, which is very decent. My old SanDisk Ultra brand memory card only achieves 7-8MB/s here. So that already shows that this Micro SD card is significantly faster than my SanDisk, which I didn't expect.

I am therefore very satisfied with the card and can definitely recommend it!

» I was allowed to test both the 32 GB and the 64 GB versions and noticed differences.

While the 32GB version didn't run reliably in my Mac at all, the 64GB version did so without any problems.
Unfortunately, the speed that is promised is not quite achieved. In various tests, even with H2testw, I did not get over 42 MB/s when writing and 82 MB/s when reading, which is not bad, but it is promised much more, which costs one star.

The SD cards are in a higher price range, which in my opinion they are not necessarily worth, since the quality is sometimes problematic in connection with other platforms. They are certainly interesting cards for a simple surveillance camera, but I wouldn't trust the cards with important data because I could use cheap cards right away.

The K&F Concept microSDXC UHS-I memory card 64GB is delivered together with an SD card adapter in a transparent packaging and can be removed relatively easily from the same. According to the manufacturer, it is advertised as a UHS-I U3 card, so it should have a write speed of at least 30 Mbytes/s.

Like the manufacturer, I used the "H2testw" tool to test the SD card's speed. For the test, I had a 1GB file written and read via a 3.0 USB interface with a USB 3.0 card reader. H2testw achieves a write speed of 42.0 Mbyte/s (23s), the read speed is 77.7 Mbyte/s (12s).

Conclusion: The card and the adapter are well made, and the contacts also make a solid impression. This card is more than fast enough for use in a 4K trail camera, action cam, surveillance camera or dashcam!

As usual, the microSD comes with an SD card adapter.

I tested the memory card with CrystalDiskMark 8 and also achieved maximum values ​​of 95 MB/s when reading and almost 50 MB/s when writing (mean values ​​from 5 runs).
This fully covers the manufacturer specifications and this is very satisfactory.
Technically there is nothing to complain about, but the price bothers me.
At currently €19 or €20, the card is simply too expensive.

A SanDisk Extreme with partially better data and faster writing speed, also with the included adapter, currently costs €10.99, a little more than half that.

So: The card is great but the price is just too high.
