Professional reviewers praise the Ultra Flair for its near-advertised read speeds, solid metal construction and useful security features, but criticize its slow sustained write speeds, limited cache and the fact that its performance falls short of newer SSD-based USB drives.
Everyday users love the drive's fast reads, durable metal look and cross-platform plug-and-play convenience, but many complain about heating, occasional failures after a year, the tiny form factor leading to loss, and write speeds that don't match advertised claims.
“Great for video projects”
“Works perfectly with MacBook and Windows”
“Durable and stylish”
Professional reviewers praise the promised read speeds and ultra-small form factor but criticize the plastic build and throttling of write performance under load.
