I’m not sure what makes this an SD card for a spy camera, it’s just a standard SD card. Not massively fast, but plenty quick enough for 64GB, happily takes photos and videos and is instantly recognised when plugged into a Windows 10 computer, no additional formatting etc. required.
In my opinion, as someone who uses a digital camera, you can never have enough SD Cards – keeping track of what is on them is another matter!
I have several spare SD Card adapters, so I just slotted this microcard into an adapter and it was ready to go in my Canon EOS camera. The only caveat is that I am not familiar with the manufacturer’s name, so it is only kept for those occasions when I run out of well-known, branded cards.
The micro format allows the card to be used in a variety of other devices, such as mobile phones, to add extra storage.
Transfer rates to/from the card are adequate and are close to the aforementioned branded cards.
I have only tested it with photos and have not tried video clips.
Please note that this is a review of the 64GB microSD card and not the camera currently displayed in the advert.
The unbranded card is supplied in a cardboard and plastic holder. The holder can be clicked open to remove the card. This is much easier than most microSD card packaging. Its even possible to retain the packaging for later storage if required.
No SD card adapter is included, but most people will probably have several of these already.
Many cards available online are either faulty, lower capacity than advertised or slower speed, so I put this one through its paces.
Plugging it into a USB 3.0 port on a computer using a microSD to USB A (2.0) adaptor showed it as having a usable capacity of 58.24 GB and it was pre-formatted to FAT 32. The usable capacity is correct for a formatted 64GB microSD card.
Using partition manager software, I did an in-depth scan of the cards ‘surface’ (actually a test of individual solid state transistors for a microSD card). This identified a total of 2251 bad sectors. If the microSD card were used “as is” these could lead to data loss or corruption. Luckily it can be easily “fixed” from Drive>Properties>Tools>Check. I would always recommend doing this on any new microSD card.
The same software was used to test sequential read and write speeds using the above connection method:-
sequential read = 18.21 MB/s
sequential write = 13.70 MB/s
Overall, this card performs reasonably well but loses a star due to being supplied with bad sectors. If you are not aware of it, this could lead to corrupt data.
This 64GB Micro SD-Card is marketed for use with a mini spy camera and when delivered it contains a folder labelled “VIDEO” and a text file called “time” waiting for the files. Other than that is appears to be a standard Micro SD-Card labelled with the symbols “U3”, “C10” and “I”, symbolising; U3 ultra high speed class 30MB/s sequential write speed for video recording, C10 minimum write speed 10MB/s – which is not as much information as many other Micro SD-Cards.
I ran a CrystalDisKMark test on the card and the results are shown in the attached pictures. I ran the same test immediately afterwards on the same PC with a Sandisk “Extreme Pro” Micro SD-Card with the following symbols; “64GB”, “U3”, “A2”, “V30”, “XC I”
Comparing the results there seems to be close correlation between them (all MB/s) – review card quoted first in each pair:
SEQ1M Q8T1, Read: 36.91 36.07, Write 23.28 34.39
SEQ1M Q1T1, Read: 36.91 36.08, Write 22.64 33.35
RND4K Q32T16, Read: 5.62 5.98, Write 1.33 2.28
RND4K Q1T1, Read: 5.07 5.78, Write 1.08 2.02
The Sandisk cards is supposed to be one of their best, so this is a harsh comparison!
The numbers printed in faint text on the back of the card did not flag up any further information when I searched for them on the Internet.
The card does not come in a storage case, nor is it supplied with an adapter to turn it into a full size SD-Card. This makes it vulnerable to getting lost. This can be mitigated to some extent as the packaging can be reused if you open it carefully.
I have put the card into an Owltron security camera that records 24/7 on a rolling basis. If it fails I will update this review – until then it is five stars.
I requested this for use in other than the mini spy camera which I dont have. The card was formatted fat32 on 1/1/2020 so is quite old stock or the date was fudged for some reason. It came with a single file called time and a folder named Video. I checked the cards capacity, its reported at 64GB so no problem with size, I transferred files to and from it without error or delay so I am pleased with the card.
