The Guru of 3D published a review on the Plextor EX1 Portable USB 3.1 Gen 2 SSD
A quote from the article:
We review the lightweight yet stupendously fast Plextor EX1 Portable USB SSD. It a very fast portable storage unit based on a USB 3.1 Gen 2 connection offering it a full 10 Gbps connection. Basically this product has the DNA of an SSD and can reach over 500 MB/sec on both reads and writes - making this an seriously fast storage unit that is easy to carry around.Plextor EX1 Portable USB 3.1 Gen 2 SSD Review @ Guru3D
