When it comes to choosing the right sd memory cards for your camera or other devices, two popular options stand out: the SanDisk Extreme PRO SDXC UHS-I and the Lexar Professional 2000x SDXC UHS-II. Both of these high-performance cards are designed to provide fast read and write speeds, making them ideal for applications such as photography, videography, and data storage. However, there are some key differences between them that set them apart.

Speed Comparison

The SanDisk Extreme PRO SDXC UHS-I card offers read speeds of up to 95MB/s and write speeds of up to 90MB/s. While these speeds are certainly fast, they are outpaced by the Lexar Professional 2000x SDXC UHS-II card, which boasts read speeds of up to 300MB/s and write speeds of up to 260MB/s. This significant difference in speed makes the Lexar card a better choice for demanding applications such as 4K video recording or high-speed burst mode photography.

UHS-I vs UHS-II

One of the main reasons for the speed difference between these two cards is the underlying technology. The SanDisk Extreme PRO uses the older UHS-I (Ultra High Speed) interface, which has a maximum theoretical speed of 104MB/s. In contrast, the Lexar Professional 2000x uses the newer UHS-II interface, which has a maximum theoretical speed of 312MB/s. This means that the Lexar card is capable of taking full advantage of the faster speeds offered by UHS-II, making it a better choice for devices that support this interface.

Capacity and Compatibility

Both cards are available in a range of capacities, from 32GB to 512GB, making them suitable for a wide range of applications. In terms of compatibility, both cards are designed to work with sd memory cards slots found in most cameras, camcorders, and other devices. However, it's worth noting that the Lexar Professional 2000x requires a UHS-II compatible device to take full advantage of its faster speeds.

Durability and Reliability

Both cards are built to be durable and reliable, with features such as shock resistance, temperature resistance, and protection against extreme environments. The SanDisk Extreme PRO is also resistant to X-rays and has a lifetime warranty, while the Lexar Professional 2000x has a limited lifetime warranty.

Price Comparison

In terms of pricing, the SanDisk Extreme PRO SDXC UHS-I card is generally more affordable than the Lexar Professional 2000x SDXC UHS-II card, especially at lower capacities. However, the price difference narrows as you move to higher capacities, and the Lexar card may be worth the extra cost for its significantly faster speeds.

Conclusion

In conclusion, when it comes to choosing between the SanDisk Extreme PRO SDXC UHS-I and the Lexar Professional 2000x SDXC UHS-II, the decision ultimately depends on your specific needs and budget. If you're looking for fast read and write speeds and have a device that supports UHS-II, the Lexar card is the clear winner. However, if you're on a tighter budget or don't need the absolute fastest speeds, the SanDisk Extreme PRO may be a more affordable option. Regardless of which card you choose, sd memory cards from reputable manufacturers like SanDisk and Lexar are sure to provide reliable performance and help you capture your memories with confidence.
