Bests & Worsts Reviews from Amazon

I own a bunch of external USB drives from various companies and various speeds. I was so excited to get this drive that promises transfer speeds upto 1000MB/s and when I connected it to my PC and tried copying a few files, I was shocked to see that the copy speeds were close to 30MB/s from my NVMe M.2 hard drive. I tried copying different types of files - photos, videos, movies etc. Same results. To make sure that the problem was with this drive and not the USB port, I tried copying the same files to my Samsung T5, I got my typical speeds of 250-500 MB/s with the T5. As a last resort, tested this Sabrent Drive with Crystal diskmark software and the software too was only getting less than 40MB/s at best. A random 4K read clocked was only 18.65 MB/s. It wouldn't take a genius to guess that I immediately initiated the return of this device. I am not sure if I will go for this brand again.
