Lexar 2000x UHS-II V90 128GB SD Card
The Lexar Professional 2000x UHS-II SDXC memory card comes in sizes from 32GB to 256GB.
Tested Write Speed: 228MB/s

Rated Sustain: 90MB/s
Warranty: Limited 10-Year Manufacturer Warranty
With a maximum rated read speed of up to 300MB/s and a write speed that tops out at 260MB/s, the Lexar 2000x cards are some of the top-of-the-line UHS-II V90 cards. They are capable of handling 4K and even some 8K video recordings, as well as capturing high-resolution stills at rapid frame rates. This makes them an excellent choice for those who need to record without concerns about lag or interruptions.
With its v90 rating, the Lexar 2000x is guaranteed for any video recording with a bitrate up to 720Mbps.
Real-World Memory Card Performance
Using the AJA System Test with the Prograde UHS-II + CFeB Reader, the Lexar 2000x UHS-II performs well with USB-C memory card readers in Windows 10, but I’ve yet to see it perform at its rated speeds, and cards like the Sandisk Extreme Pro UHS-II are slightly faster. However, when looking at compatibility and in-camera performance, the Lexar cards always come out as some of the top performers.
| Memory Card Name | USB-C Write | USB-C Read |
| Lexar 2000x UHS-II 128GB | 228 MB/S | 256 MB/S |
Here is a Disk Write Capture taken with a 64GB test.
When looking at the sustained disk writes, the speed starts a little slower at first but then hits its top speed of around 244 MB/s giving us an average of around 228MB/s.
Compatibility
The Lexar 2000x comes in three sizes with two file systems. The 32GB cards are SDHC cards and operate with a 32-bit file structure. The 64GB cards are SDXC and function with a 64-bit file structure. With SDHC cards, because of the 32-bit file structure, they will limit video recordings to 4GB before chaptering and breaking the recordings into separate clips.
UHS-I / UHS-II devices
Speed Class: V90
Reliability
The cards come with the standard dimensions of SD cards but are immediately recognizable by the gold accent on their label, indicative of their premium status within the Lexar lineup. They are constructed with the same robust plastic and feature two rows of connections on the rear, signaling their UHS-II status.
When testing in different cameras the Lexar 2000x rarely has problems and Lexar as a brand makes some of the most camera-friendly cards out there.
