Lexar Professional 633x 200GB microSDXC UHS-I U1 Memory Card Review
Introduction
Lexar Professional 633x microSD cards offer UHS-I performance for action cameras, phones and tablets. The 633x card offers up to 95MB/s read speed according to Lexar. Although no write speed is not quoted, the UHS Speed Class 1 (U1) card rating means the card will support at least 10MB/s continuous write speed making it suitable for HD video recording. The largest capacity card is the 200GB (LSDMI200BBNL633R) which was tested for this review. Additional 633x microSD cards are available in 16, 32, 64 and 128GB capacities.
Lexar Professional 633x series memory cards are covered by a limited lifetime warranty. The 200GB microSDXC card tested was made in Korea.
Included microSD Memory Card Reader
Lexar Professional 633x microSD cards are sold with a microSD memory card reader. This compact reader supports UHS-I microSD cards. A separate test of the included Lexar LRWM03U-7000 microSD card reader can be found in the card reader reviews.
Performance
In card reader benchmark tests the 200GB 633x microSD card measured up to 91.5 MB/s sequential read speed. This is slightly below the 95MB/s speed rating quoted by Lexar. The write speed reached the highest squential read speed of 37.4 MB/s in the included LRWM03U-7000 UHS-I microSD card reader.
With 200GB capacity, the Lexar 633x microSD card can hold tens of thousands of images, or hours of HD video. The card was tested in GoPro HERO4 Black and supported all video modes including 4K 30p recording.
