Patriot LX Series 128GB microSDXC Memory Card Review

Patriot recently released a 128GB capacity of their LX Series microSDXC cards. The LX is intended for use with HD camcorders and mid-range cameras, but can be loaded into SD host devices with its SD adaptor. It has standard Class 10 SD Association compliance, and the same reported transfer speeds as the 64GB model (70MB/s and 20MB/s for read and write, respectively). As with the rest of the LX Series, the card comes with Patriot's 5-year warranty and has an MSRP of $129.99.

Performance

In this review, we include the following comparables from our database of memory card reviews:

Using our HP Z620 Consumer Testing Platform, we measured transfer speeds from the new Patriot LX Series 128GB microSD card with IOMeter. The LX dominated the competition in both read (by a factor of two) and write (81.07MB/s and 20.77MB/s, respectively). The SanDisk Ultra, Samsung EVO, and Toshiba cards posted 44.66MB/s read and 14.29MB/s write, 44.4MB/s read and 19.1MB/s write, and 34.3MB/s read and 12.1MB/s write, respectively.

The LX also outperformed the other cards in random large-block transfers (with the exception of the Samsung EVO in write performance), though not by quite so dramatic a margin; 58.66MB/s vs. 43.98MB/s (SanDisk), 43.9MB/s (Samsung), and 33.1MB/s (Toshiba) read and 6.57MB/s vs. 2.45MB/s (SanDisk), 32.0MB/s (Samsung), and 1.6MB/s (Toshiba) write.

In a random 4K IOPS benchmark, the Patriot posted 982.41 IOPS read and 254.85 IOPS write.

Conclusion

Patriot has expanded the microSD family of their LX Series with the new 128GB card. It can be used with microSD-loading HD cameras (or regular SD via the SD adaptor) or anything leveraging the tiny form factor for high-capacity storage. Thanks to the large capacity, this microSD card could effectively serve media professionals while maintaining its appeal to more entry-level or mobile use cases. It performed extremely well compared to the SanDisk Ultra, Samsung EVO, and Toshiba cards, nearly doubling all of their sequential read performances. With the exception of the Samsung EVO's random write, the Patriot LX outperformed every other card in all of our benchmarks.

Pros

  • Excellent sequential and random performance
  • Large capacity for a microSD

Cons

  • Large block write is the only area it didn't lead

The Bottom Line

The Patriot LX Series 128GB microSD posts impressive numbers overall while still providing large storage capacity for both entry-level users and media professionals.
