Now, you should have an overall understanding of SanDisk vs Lexar. To know a more detailed comparison of the two brands, let’s keep reading the following part.

Lexar vs SanDisk SD Cards: 4 Main Differences

According to the above introduction, we know both Lexar and SanDisk SD cards have similarities like storage capacities (ranging from 32GB to 1TB), U ratings (UHS-I and UHS-2), Usage, and Video speed class.

However, there are 4 main differences between Lexar SD card vs SanDisk, including data transfer speed, marketing, price, and reliability. Let’s start exploring them.

Data Transfer Speed

Data speed is an important factor especially for those who want to store or transfer videos using less time. SanDisk vs Lexar SD cards, which is faster? The answer depends on the U ratings and SD card type. It’s obvious that UHS-11 and SDXC are faster than UHS-1 and SDHC.

Further reading: Do you want to know the differences between SDHC vs. SDXC? This post explained the topic in detail.

According to the comparison of best-selling Lexar and SanDisk SD cards, we can find that the two SD cards have different data speed even with the same U-rating and card type. For example, a Lexar Professional 1667x UHS-II SDXC card has the maximum read and write speeds of 250 MB/s and 120MB/s, while a SanDisk Extreme Pro UHS-II SDXC card has maximum read and write speeds of 300MB/s and 260MB/s.

However, the above data speeds are a theoretical number of the maximum transfer speed. In reality, the actual data transfer speeds depend on specific memory cards. For instance, the form factor, adapter included, and even capacity have an impact on the transfer speed of an SD memory card.

Do you want to get the exact speed of Lexar or SanDisk SD cards? MiniTool Partition Wizard can help you compare SD cards easily like A1 vs A2 SD cards, and U1 vs U3. It is a multiple partition manager that boasts many powerful features such as Disk Benchmark, Convert NTFS to FAT, Migrate OS to SSD/HD, etc. Here we will show you how to test the transfer speed of your SD card using the MiniTool software.

Step 1. Plug your memory card into a card reader and connect it to your computer.

Step 2. Launch MiniTool Partition Wizard to get its main interface and click on the Disk Benchmark feature on the top toolbar.

Step 3. Select the drive letter of your Lexar or SanDisk SD card from the drop-down menu, and then further specify the test parameters based on your demands, and click on the Start button.

Step 4. After a little time, you will see the test results, including random/sequential reading and writing speed.


Another big difference between Lexar SD card vs SanDisk is their marketing strategies. If you are a casual buyer, you may consider these factors like data speed, capacity, price, and whether or not a given memory card is used for video.

However, for those professional consumers like photographers, the biggest difference between memory cards is in marketing. This is because most casual consumers don’t take the card as the most important part they choose for their device, but a photographer will.

According to the above information, we could know both Lexar and SanDisk memory cards have different market positioning. For instance, Lexar Professional 2000x/SanDisk Extreme Pro has good performance on the 4K/8K video and 3D camera, while Lexar Professional 633x/SanDisk Extreme cards fit for 4K video and photography.

Therefore, if you are a normal consumer and don’t use your device frequently, we recommend you choose a relatively cheaper and simpler model like Lexar Professional 633x/SanDisk Extreme. Of course, if you are a professional photographer and get one of the best cameras in the world, you’re probably better off using a more advanced card like Lexar Professional 2000x/SanDisk Extreme Pro.


There is no doubt that reliability is the most important quality of an SD card. This is because if your memory gets damaged or cameras fail accidentally, chances are the videos and pictures in the card lose forever. It is true especially for those who often use the SD camera card in extreme environments.

With the development of technologies, most modern memory cards improve their reliability and perform well in extreme environments. In terms of reliability, the series of SanDisk Extreme should be one of the most reliable cards. They are waterproof, shockproof, magnetic proof, temperature proof, and X-ray proof. In addition, SanDisk is the go-to card manufacturer for GoPro owners due to the guarantee to endure harsh environments.

However, not all Most Lexar memory cards are waterproof and work well in other extreme environments. Most Lexar cards are relatively reliable, but a small number of them are reported to fail within their lifespans. Additionally, SanDisk cards have a longer limited lifetime warranty than Lexar in general. So, SanDisk wins in the category of reliability.


The last difference between Lexar vs SanDisk SD cards is their prices. According to the data we gathered, SanDisk card lineups are slightly expensive than Lexar card lineups. Usually, the larger capacity your memory card holds, the more money you need to pay for. For example, with the same capacity and U-ratings, a 64GB of a Lexar Professional 2000x UHS-II card is sold $89.99, while a SanDisk Extreme Pro UHS-II 64GB SDXC card charges you $139.94.

Lexar vs SanDisk: which is better? According to the comparison, I believe that you already have an answer. Personally, I would prefer to choose a SanDisk memory card because of its overall high quality. Spending a few more dollars for a more reliable one is a good deal.
