External drive reviews are quite simple and straightforward; I ran the test on both USB 3.0 and USB 2.0 ports just to give you an idea of what to expect if your laptop or desktop doesn’t come with USB 3.0 port. I am using CrystalDiskMark X64 as my benchmark, note that the sequential(seq) result is pretty much the same as real life transfer test. The drive is formatted with the NTFS file system so only 931GB is usable.
First, let’s we talk about the performance over USB 2.0, the speed is actually pretty good, 44MBs read and 45MBs write. If you’re copying a 1GB file it will take about 23 second to finish, how about the USB 3.0?
During the test I noticed that the Lenovo F309 have two different LED colours which is Red and Blue. At first I thought the blue is on idle mode while the red LED on load but I was totally wrong. Actually, if you plug the drive into a USB 2.0 port, the blue LED will light up and the red LED indicates that the drive is connected to a USB 3.0 port.
