Lexar vs SanDisk: Speed Comparison


Now, to really identify which memory card brand is better, let us talk about the speed of the memory cards offered by the two brands.

SDHC vs SDXC

SanDisk and Lexar both offer memory cards that are SDHC and SDXC, but what is the difference between the two?

  • SDHC – this are cards with a storage capacity of 16 GB up to 32 GB
  • SDXC – 32 GB and higher memory cards are classified as SDXC

  • Class 10 this SD Cards that are rated at CLASS 10 has a write speed of up to 10 MB/sec. It is designed to record video with a maximum resolution of 1080p.

The number one spot is claimed by SanDisk Extreme Pro’s 128 GB + 64 GB storage bundle. On the other hand, Lexar Professional 633X’s 32 GB + 64 GB storage bundle earned the number two spot.

These cards are catered for completely different memory card user and the price difference is quite huge. SanDisk Extreme Pro’s bundle is priced at $58 compared to Lexar Professional’s $19 price tag.

Lexar vs SanDisk: Reliability


In terms of reliability, SanDisk memory cards are waterproof, shockproof, temperature proof, magnetic proof, and X-ray proof. The cards from SanDisk are guaranteed to endure harsh environments which why they are the go-to card manufacturer for GoPro owners. On the other hand, not all Lexar memory cards offer water and other extreme environment resistance.

SanDisk wins this category by a margin given that all of their cards are designed to perform even on the harshest outdoor conditions. Also, both SanDisk and Lexar memory cards offer lifetime limited manufacturer warranty on most of their memory card models.

 

Lexar vs Sandisk: The Verdict


After comparing the two brands, SanDisk is still at the top of the competition in terms of their memory cards. They have a good lineup of memory cards that cater to different kinds of users. Their cards are also equipped with better all-around performance compared to other memory card brands. Another thing to add up is the reliability of their cards across all models to withstand extreme outdoor conditions.

However, this doesn’t mean that Lexar cards are terrible. They are also great but with a few downsides. If you are willing to sacrifice reliability and some performance in exchange for a cheaper price then you can consider buying Lexar memory cards.

Best SD Card for your Camera

Check out one of  SanDisk’s memory card.  The SanDisk Extreme Pro is a great companion for your professional cameras. It has support for 4k video recording and sequential burst mode photography. It is rated at UHS speed class 3 with write speeds of up to 90 MB per second. In terms of transfer speed, the card is well equipped with 170 MB per second read speed. These features are important for the memory card to keep up with most of your camera’s functions.

For example, a GoPro camera would need to encode 7.5 MB of data per second on your memory card if you are shooting videos at a resolution of 4k and 60 frames per second. Having a memory card that has a write speed lower than 7.5 MB per second would result in memory card errors, frame drops on videos, and file corruption.
