Have a BlackVue dash cam but wish to run a non-BlackVue SD card? Not all SD cards are compatible with BlackVue dash cams - some perform better than others while others may lead to freezing, buffering, or corruption issues. BlackVue recommends BlackVue brand SD Cards for their dash cams. However, not all users will wish to use the BlackVue brand card. For those users, please see below for a post published on the BlackVue UK Forums regarding which memory cards have performed the best.
Note: The post below belongs to BlackVue UK on the BlackVueShop UK Forums. Their opinions and reviews does not represent the view of DashCam Bros. BlackVue recommends using BlackVue brand memory cards with their products. Proceed with caution with using non-BlackVue memory cards.
General considerations for Micro SD cards are the type of memory used (MLC, SLC, TLC) which will limit the number of write cycles. MLC is the most expensive and best.
SanDisk, Samsung, Transcend and the newer Blackvue supplied cards all have MLC (Multi-Level Cell) technology so we are unsure why some perform better. The new Blackvue cards even have MLC on them
The only difference is Read /Write speed and we find the faster the card the more macro blocking and pixilation occurs.
Most of these cards perform well in the Blackvue camera but others can cause issues with quality of footage. It is so important to get the correct 64GB micro SD to optimise the performance of your Blackvue DR650GW-2CH, DR750LW-2CH and DR600GW In Car Dashcams.
Our conclusions are that superfast cards like the SanDisk 64GB SanDisk Extreme Plus 80MB/s and Samsung 64GB Pro 80MB/s need to be avoided, these cards are simply just too fast and are the worst offenders for macro blocking or pixilation on Blackvue Cameras.
These superfast cards also tend to make the Blackvue overheat more as well, although the Blackvue Camera can cope with operating temperatures of up to 60℃. Despite the Blackvue Dashcams operating temperature being high, in a hot summer it could be an issue in many countries.
Both the SanDisk 64GB Ultra and Samsung 64GB EVO which are the next series down also overheat the Blackvue more than other brands we tested.
The SanDisk 64GB SanDisk Extreme Plus 80MB/s states as a title on the SanDisk website "Great Choice for Your Android™ Smartphone or Tablet". The Samsung 64GB Pro 80MB/s states "Compatible Device Smartphone, Tablet" and for use in high-end Smart phones and Tablet PCs."
So from the above we can only assume the Samsung and SanDisk are optimised for Smartphones or Tablets although the SanDisk Extreme Plus is highly recommended by GoPro.
So avoid these superfast cards and look for lower read/write speed Micro SDs , 64GB Micro SDs that run between 20MB/s -45MB/s are perfect for the Blackvue Car Cameras and perform the best.
We tested 6 64GB Micro SD cards in total over a period of a few months in all Blackvue 64GB compatible models , the following information is our ratings from our testing.
This information is our findings and opinion only on branded non Blackvue cards, this does not necessarily represent the opinion of everyone so please bear this in mind 
.
We are not saying none of these cards are no good, they all work well and do the job. We are rating the 64GB Micro SD cards out of 10 in terms of their performance and the quality of recorded footage upon playback which we think is important overall.
6. SanDisk 64GB Ultra Class 10 UHS-1 Micro SDXC Card
The SanDisk 64GB Ultra with a read speed of up to 30MB/s and a lower write speed is nowhere near as fast as the 64GB SanDisk Extreme Plus 80mb/s we mentioned above to avoid.
SanDisk has known performance issues on many Dashcams products in terms of the way Dashcams write data. SanDisk works perfectly fine in most digital cameras or other products but not Dashcams unfortunately, this is because it uses a non-standard chip controller inside the card.
On the manufacturers website it states the following "Ideal for compact to mid-range point-and-shoot cameras".
Do we class the Blackvue Dashcams has a mid-range point-and-shoot camera?
We at Official Blackvue Shop UK certainly class them has premium Dashcams especially with the higher pricing compared to other cheaper Car Camera brands. Maybe that's why they don't perform as good as the other 64GB Micro SDXC cards we have tested.
Although it also states "This memory card features Class 10 video rating for high-quality video recording, so you can capture cinema quality 3D, Full HD and HD video without dropouts and stuttering. Support may vary based upon host device, file size, resolution, compression, bit rate, content and other factors.
So it seems from the above statement it ultimately depends on the device, file size, resolution compression and bite rate, factors which are important and relevant to the use of Blackvue Cameras.
It’s still a great card and more than adequate for the job but we are rating on performance in Blackvue Dashcams only while comparing it to other Micro SD brands which we feel are better performing.
This is why we have it at number 6 , if we were to rate this card performance in a Blackvue Dashcam compared to the other 64GB Micro SDs we tested we would give it a 7 out of 10.
5. Samsung 64GB EVO UHS-1 Grade1 Class 10 Micro SDXC Card
Samsung uses fine-quality NAND flash memory chips, they have been the market leader and number one in memory since 1993. Samsung has a solid reputation for manufacturing high-performance, top-quality, premium-designed products.
Without doubt these cards perform outstanding in mobile devices with transfer speeds of up to 48 MB/s. That is probably the issue in terms of performance in Dashcams.
It does state on manufacturer’s webpage “The EVO model boasts ultra-high-speed performance and is the preferred memory card for your smartphones, tablets, full HD (FHD) camcorders and digital single-lens reflex (DSLR) cameras."
So it seems they are not optimised for Dashcams or in this case Blackvue although it does state “full HD (FHD) camcorders”. Again the Blackvue overheats more with this card installed like the SanDisk and more than the other cards we tested.
Samsung 64GB EVO UHS-1 Grade1 Class 10 Micro SDXC cards are still not perfect but are better . Again we are not 100% happy with performance but they are better than the SanDisk.
As regards rating we would give it a 7.5 out of 10.
4. Kingston 64GB Class 10 UHS-I Advanced SDXC Memory Card
Kingston Technology is one of world's largest independent manufacturer of memory products since 1987. They produce reliable memory cards offering the consumer a lifetime warranty as well.
This Kingston 64GB Micro SDXC is the only 64GB memory card in this post that uses TLC NAND chips, this is why it’s probably mid table in terms of performance and rating when we tested in a Blackvue.
Although unrelated to this post most 128 GB Micro SDXC cards like SanDisk and Lexar still use TLC NAND and so far there is not one 128GB MLC Micro SD Card on the market that we know off.
Apple also uses Samsung TLC chips in the iPhone 6 Plus but looks like a recall may be pending, due to the cheaper TLC flash as quoted-
“Reports are circulating that the recent failures of 128 GB iPhone 6 Plus models are due to the use of TLC NAND. Apple is the world's largest flash consumer, and has made a concerted effort to utilize technology to expand their use of less-desirable flash (i.e. 'cheap'). TLC NAND, which holds more bits per cell than MLC NAND, has a higher capacity than other types of NAND"
The above is just to give you an idea of the differences between MLC and the cheaper TLC NAND.
Again as per Manufacturers description we have no mention of any use in Dashcams, this will become apparent in our top 3 Micro SD cards. It does state about HD video but nothing more -
"This Kingston Class 10 UHS-I micro SD is perfect for apps, music, photos and videos that take up significant space on a smartphone or tablet. Compatible with micro SDHC and micro SDXC devices, its fast UHS-I speed allows users to capture photos and HD videos without interruption"
Overall the card is not the fastest in terms of read or write speeds which is not a bad thing in terms of a Blackvue Car Cameras performance with faster Micro SD cards.
What was interesting it recorded longer than any other card we tested before rewriting over the older recordings, this is the TLC NAND probably holding more bits per cell.
Everything about its performance in Blackvue Cameras was average and neither good or bad, its offers good reliable performance.
In terms of rating we would give it an 8.0 out of 10.
The Top 3
The following is what we rate as the top 3 64GB Micro SD cards for the Blackvue DR650GW-2CH, DR600GW and DR750LW-2CH Vehicle Drive Recorders.
This is where things start to change in terms of what the manufacturer states in their description, like what devices the 64GB Micro SD card can be used in which just happens to include tablets, sports camcorders, and smartphones with support for 1080p Full-HD, 3D, and 4K video.
Is this a coincidence that these 3 cards are the best performers in the Blackvue Cameras?
We don't think so, especially when In Car Cameras and action cameras are becoming a growing market that need good performing memory to optimise their performance.
It seems our recommended top 3 Blackvue 64GB Micro SDXC cards have no issue stating on packaging or description about compatibility with action or Dashcams, something the first 3 Micro SDs didn’t.
Clearly they have been tested for this use as well along with smartphones and tablets, 2 of the cards are actually recommended for use in the GoPro, the world’s best action camera brand.
3. Transcend 64GB Micro SDXC Class 10 UHS-I 300x Premium
Transcend like Kingston specialise in memory products and carry over 2000 products, including all types of memory modules, flash memory cards, USB flash drives, digital music players, card readers, external hard drives, solid state drives and industrial-grade products, to satisfy virtually every possible memory-related requirement.
We originally had this in our number 1 position before we tested other 64GB Micro SDXC cards with the Blackvue Car Cameras. The Premium Transcend 64GB Micro SDXC Class 10 UHS-I 300x offers read/write speeds of up to 45 MB/s read and 25MB/s write, these read/write speeds which we discussed before are perfect for Blackvue Dashcams.
Transcend's 64GB Micro SD Class 10 UHS-I cards are optimised to meet the rigorous demands of high-resolution image capture and smooth Full HD 1080p, 3D and even next-generation 4K video recording.
It is an ideal upgrade for smartphones, tablets, digital cameras and camcorder offering smooth Full HD, 3D, and 4K Video Recording Capabilities and performance needed in Blackvue 64GB compatible Dashcams.
The manufacturer quotes the following below in description and finally mentions Car Driving Recorders-
"Easy-to-use, Plug & Play Operation
Transcend’s Micro SDHC/SDXC Class 10 UHS-I 300X cards are perfect for today’s high-end mobile devices, including smartphones, eBook readers, portable games consoles, driving recorders, and the increasingly popular tablet PCs
Overall Transcend's 64GB Micro SD offers smooth Full HD video footage at high-speed in Blackvue Car Cameras. It is a great overall performer and recommended by many Dashcam enthusiasts everywhere has the card of choice, we have read about reliability issues but the Transcend memory cards come with a limited lifetime warranty anyway.
It states on the manufacturer’s page under compatibility tab that it is in incompatible with the GoPro HD HERO3 Black, Silver and White Edition. The top 2 cards come highly recommended by GoPro which maybe proves significant in their position has the top 2 64GB Micro SDs from our testing.
The Blackvue Dashcams do not overheat as much with this card installed compared to cards above, recording times before overwriting are normal and what we would expect in a Blackvue Dashcam using a 64GB Micro SDXC (about 12-16 hours).
For the overall rating we would give the Transcend a 9.0 out of 10, it was originally number 1 before we tested the last 2 cards.
2. Lexar High-Performance Micro SDXC Class 10 UHS-I 300x
Lexar is an American manufacturer of digital media products and has been trusted as a leading global brand of memory solutions for more than 15 years.
As a brand of Micron they offer a full range of memory products through consumer brands, Crucial and Lexar. Micron is one of the largest memory manufacturers in the world, their award-winning line-up includes memory cards, USB flash drives, readers, and storage drives for retail and OEM customers.

The Lexar High-Performance Micro SDXC Class 10 UHS-I 300x is the first 64GB Micro SD in this list to state MOBILE/SPORT and Sports Camcorder on actual product packaging. As per picture below -
Blackvue In Car cameras might not be classed has Sport Camcorders but the fundamentals are same, to record crystal clear footage in Full HD 1080p at high speed.
In our opinion Blackvue cameras are Action Cameras for vehicles, high quality footage is really important which this Lexar 64GB Micro SD delivers when used in compatible Blackvue Car Cameras.
Macro blocking, stuttering and pixilation is minimal, the Blackvue also runs at what we class has average temperatures for these devices under normal circumstances (about 25˚C to 35˚C).
Performance is well above the standard of any of the above 64GB Micro SDs listed.
Why isn't it number 1?
Plain and simple, we just thought the next 64GB Micro SD was slightly better overall in performance, we give this Lexar card a truly deserved 9.5 out of 10.
At last we introduce the 64GB Micro SD in 1st place below. Most people reading this post will probably find our choices for the top 2 64GB Micro SD's unusual, some probably have never heard of the Micro SD brands.
Most people who buy memory for their Blackvue Dashcams will buy Samsung or SanDisk, these brands are well established Micro SD brands so you would 100% expect these to be the most popular purchases.
We at the Official Blackvue Shop UK have even sold these cards in the past without any issues.
This does not necessarily mean they are the best for use in every device like Dashcams. Only the top 3 memory cards made any reference to Sport Camcorders, Action Cameras or Dashcams in the manufacturer’s description, the top 2 actually advertise it on the product packaging.
This is probably because they are tried and tested in these devices, GoPro recommends both the Lexar and Delkin brands in their Action Cameras.
We at the Official Blackvue Shop UK who run this forum are Dashcam geeks and look into every detail, based on the data we collected during extensive testing periods we have rated the 64GB Micro SDXC cards overall performance in Blackvue Cameras only.
Also we are not saying the other cards at the top of this list are no good either for Blackvue In Car Cameras, they do a great job but some just simply outperform others in many different ways. We have just posted our results from testing for you guys to make your own decision based on your specific requirements.
We hope the information helps, below is our number 1 64GB card for the Blackvue DR650GW-2CH, DR600GW and DR750LW Car Cameras.
1. Delkin 64GB Micro SDXC 375X UHS-I (Speed Class 1) Memory Card
Delkin Devices, Inc. is an independently owned business and the largest US memory card manufacturer in San Diego, CA. Today the Delkin name is associated with paramount quality, professionalism and most importantly innovation, serving both industrial and consumer markets worldwide.
In the past decade, the company has paid particular attention to the professional photography industry, but manufactures accessories to be used across digital SLR and point and shoot cameras, mobile phones, PCs, notebooks, music players, and even gaming consoles.
A lot of people will probably have never heard of this brand, like us until it landed on our desk as a sample we had never heard of this brand either or would have even considered it for use in any Blackvue car camera or Dashcam.
Like all the sample stuff that we get sent we are always open to trying new brands and thoroughly testing in the devices we sell.
As stated previously before the Lexar and the Delkin branded cards were tested by us we had Transcend at number 1.
Our logic has always been "the faster the card the better the performance", surprisingly this is not the case and it is against our intuition to what we always thought or believed.
All Micro SD cards will only perform to the device capabilities that they are used in, it will bottle neck and in a Blackvue the card can only go so fast. You will never get a superfast card fulfilling its maximum read/write speed in a Blackvue Dashcam.
We think the logic is the data rate input to output as this can be the only explanation. The 2 main components that make this work in the Blackvue are the CPU (Central Processing Unit) and the Micro SD.
The CPUs used in Blackvues Car Cameras are as follows-
TI DM367 (Texas Instrument ) - DR600GW and DR3500-FHD
HI3516 (High Silicon ) - DR650GW-2CH and DR530W-2CH
TI DM385 (Texas Instrument ) - DR750LW
The CPU would control the data to/from the Blackvue car camera like what to do (read) and checks if the task is done (write), the Micro SD card would perform the actual operation like pixels to screen, bits to/from Micro SD.
The Blackvue CPU must synchronize with the Micro SD so that it doesn’t miss data or write too quickly. The Blackvue CPU at the same time is performing other tasks in background but the Micro SD card is sending the data to the CPU.
The data being transferred via the Blackvue Micro SD is waiting on the CPU asking "are you ready yet", if it’s not then this causes a small delay causing the macroblocking, pixilation and stuttering which affects performance in terms of the actual recorded footage quality.
This would also explain why the Blackvue overheats as well with these high speed cards because it’s having to work harder and is under pressure to process the data it is receiving from the Micro SD.
Although only a theory if you take into consideration that the guys who done a custom firmware removed all the unnecessary tasks the Blackvue camera performs with the CPU and managed to increase the bitrate to 17kps, nearly double the bitrate. This actually makes total sense why a high speed card does not perform well in the Blackvue.
In short the Micro SD card is waiting on the Blackvue CPU to complete its other tasks which causes the delay albeit milliseconds only but enough to affect the overall footage quality on playback. You will find this happens more at high speed and low lit areas especially when the CMOS sensor is working overtime.
As regards the Delkin 64GB Micro SDXC 375X UHS-I performance.
The Delkin 64GB card runs at about 22MB/s Read & 20MB/s Write in Class 10 mode in a Blackvue Car camera, just slightly more than the Blackvue MLC supplied Micro SD card, this is all you need for high quality footage.
Like the Lexar operating temperatures are about 25˚C to 35˚C so everything is how it should be. Again like the Lexar 64GB Micro SD card brand before it, the Delkin 64GB Micro SD comes highly recommended by GoPro for use in their premium sports camera range, so clearly it’s not that much of an unknown brand.
Again on the packaging it states "Action Camera Approved" with support for HD, 3D and 4K video, it also comes with a lifetime warranty which is always a bonus for any memory card purchase.
Recorded footage is very smooth like the Lexar, so why did we put it at number 1?
Overall we just thought that everything from performance to footage with this Delkin 64GB Micro SD card installed in a Blackvue DR650GW-2CH, DR600GW and DR750LW-2CH was perfect and how it should be.
We can’t fault the card in anyway and although slightly more expensive than the above cards, you get what you pay for and that is high quality build, performance and reliability.
Taking everything on board from all our extensive testing we rate this Delkin 64GB Micro SDXC card a 10/10 which is why its number 1 and the best 64GB card for Blackvue In Car Cameras, recommended by the Official Blackvue Shop UK.
Again we must point out this is a review on other branded 64GB Micro SD cards only and their performance, we always recommend to use official branded Blackvue merchandise in Blackvue Dashcams.
So there you have it folks and again don't take our word as gospel, this is just our opinion.
