The Apogee Astro Drive Series A101 from Chaintech is apparently the world's smallest USB 3.0 drive
Still, the Astro DRive Series A101 isn’t a slouch. The drive can see read/write speeds of 186MB/s and 130MB/s, respectively. That’s quite a bit faster than the average 30/20 that USB 2.0 generally sees and slightly higher than the speeds I’ve seen on USB 3.0 hard drives.
The series will initially be available in three storage sizes: 32GB, 64GB, and 125GB. No word on when they will be available or how much they’ll sell for, though. Hopefully for the sake of the marketers, the drives will be released soon than later as the World’s Smallest title will likely be stripped away before too long.
