Today was a continuation of the lab assignment we did yesterday with a twist. Alex asked us to benchmark all the classroom computers as well as the lab area. The purpose of which was to find out which hard drive is failing in the computers so that we can replace them with ones that are good. Afterwards, we segregated promising hard disks from the lab area which we are going as replacements. This was a group effort which everybody participated in. We put the information in a google sheet. When we were done, Alex showed us how to color code the information using conditional formatting with the use of color scales.
Alex also discussed the difference speeds for USB 2.0, 3.0 and 3.1 being 480 Mbps (60 MBps), 5 Gbs (625 MBps) and 10 Gbps (1250 MBps) respectively. However, these are ideal speeds which must be confused with the actual transfer rate which depends on the port and the device used.
