Apacer Technology Inc. has introduced two USB 2.0 flash drives. The AH521 and AH522 USB drives provide high-quality in both materials and design, including zinc alloy and electro-polished components, a retractable USB connector in a translucent casing, and a blue LED. The metal frame protects the retractable USB connector while making the drive easy to carry on a strap. When the drive is in operation, the hidden LED emits a lustrous blue light.

The AH521 and AH522 differ in color scheme, and performance. The AH522 comes in a golden metallic frame with black translucent casing. With a read access speed of up to 30MB/sec and a write access speed of up to 12 MB/sec, AH522 is also a time-saving tool for large-sized digital file. The AH521 offers a silver metallic frame with black translucent casing and a read/write speed is up to 17/6 MB/sec.
