Kingston Class 10 UHS-I 64GB SDXC Memory Card Review 90MB/s 45MB/s

Kingston UHS-I 64GB SDXC Memory Card Front

Introduction

The Kingston Class 10 UHS-I 64GB SDXC card is the workhorse of the Kingston Secure Digital card line. Its label includes various logos that describe its capabilities: 64GB (total capacity), Class 10 (SD Class 10), SDXC (Secure Digital eXtended Capacity using exFAT file system), U1 (UHS Speed Class 1), the Roman numberal "I" (UHS-I) and the card model number SDA10/64GB. The Class 10 UHS-I card offers a combination of performace and value that will appeal to a wide range of users, both enthusiast and professional. This card is available in 16, 32, 64, 128, 256 and 512 GB capacities. Here we review the 64GB size.

The Class 10 UHS-I card was previously labeled "Ultimate." Older Ultimate cards were rated 60MB/s read, 35MB/s write. These were subsequently replaced by a 90 MB/s read and 45 MB/s version. The most recent cards seem to have dropped Ultimate from the name. All versions of the card share the same model number, SDA10.

The card displays a brushed gold picture on the label along with the anti-counterfeit Kingston head logo that changes in appearance depending on viewing angle. The design is complemented by a yellow card lock slider. The bottom of the card has Kingston's lot and batch numbers and designates the card origin, Taiwan.

Performance

In benchmark testing with UBS 3.0 card readers, this Kingston Class 10 UHS-I card provided impressive performance. Maximum sequential read speed measured up to 98.5 MB/s, while write speed reached 81.2 MB/s. Both numbers are well above specification (90 MB/s read, 45 MB/s write), with the write speed over 58% higher than specified. Discovering a write speed that far above than specification feels like finding an extra $20 in your pocket. Its performance surpasses the 32GB Ultimate which tested much closer to specification.
